Abstract
We are documenting the case of An 11-year-old girl who has been followed up at our out-patient clinic since birth with clinical presentations including intrauterine growth restriction, recurrent periodic fever in infancy, hypotonia, global developmental delay, liver function impairment with cirrhotic changes, and clinodactyly. Congenital abnormalities were suspected but a series of examinations including brain MRI, liver biopsy and muscle biopsy yielded insignificant findings. Whole genome sequencing (WGS) was conducted and revealed three novel mutations (c2T > G, c1826T > C, c.556-560delAGTAAinsCT) of the COG5 gene. A diagnosis of COG5-congenital disorders of glycosylation (COG5-CDG, or CDG IIi), with neurologic presentation was established. Sanger sequencing in the patient and her parents confirmed the compound heterozygous mutation. Upon literature review, we identified the patient as the first case of COG5-CDG in Taiwan. Our study enhances the clarity of the correlation between the mutative genes and the presentation of COG5-CDG.

Abstract
Pontocerebellar Hypoplasia (PCH) is a rare autosomal recessive hereditary neurological degenerative disease. To elaborate upon the clinical phenotypes of PCH and explore the correlation between TOE1 gene mutations and clinical phenotype, we analyze the clinical and genetic features of a Chinese infant afflicted with pontocerebellar dysplasia accompanied by gender reversal with bioinformatics methods. The main clinical features of this infant with TOE1 gene mutation included progressive lateral ventricle widening, hydrocephalus, severe postnatal growth retardation, and hypotonia, and simultaneously being accompanied by 46, XY female sex reversal. Whole exome sequencing revealed a compound heterozygous mutation in the TOE1 gene (c.299T > G, c.1414T > G), with the protein homology modeling-generated structure predicting a pathogenic variation, which is closely related to the clinical manifestations in the patient. The new mutation sites, c.299T > G and c.1414T > G, in the TOE1 gene are pathogenic variants of pontocerebellar hypoplasia type 7.

Abstract
AIM We aim to describe the behavioral phenotype of children and adolescents with the good to intermediate attenuated form of non-ketotic hyperglycinemia (NKH) and to explore associations between the behavioral phenotype and age, sex, plasma glycine levels and drug treatment. METHOD Parents of children with attenuated NKH completed questionnaires assessing maladaptive behavior, adaptive behavior, social communication, speech/language development and motor development in addition to demographic and medical questions. RESULTS AND INTERPRETATION Twelve children, age 6 to 21y, functioned at mild to severe intellectual disability levels. Their speech/language development was in line with their developmental quotient. Relative to their intellectual functioning, their motor development and communication were weaker in comparison to their general development. Their adaptive behavior, however, appeared a relative strength. There was no evidence for autism spectrum disorder occurring more frequently than expected, rather social skills, except for communication, were rated as a relative strength. Maladaptive behaviors with ADHD-like characteristics were present in more than two thirds of children. Maladaptive behaviors were significantly related to female sex and to taking dextromethorphan, but no significant relation between plasma glycine levels and behavior was found. Future studies will need to evaluate causality in the observed relation between dextromethorphan use and maladaptive behaviors. Clinicians should reconsider the benefit of dextromethorphan when presented with disruptive behaviors in children with attenuated NKH.

Abstract
To prospectively investigate associations between the features of gut microbiota at the fourth week after birth in preterm infants and neurodevelopment from 1 month of corrected age to 6 months of corrected age (MCA). Seventy-seven preterm infants were recruited from three NICUs of three tertiary hospitals between Apr 2021 to Sep 2022. Stool samples were collected during the fourth week after birth. Illumina MiSeq high-throughput sequencing technology was used to detect the composition and diversity of gut microbiota. Neurodevelopment assessments of preterm infants were conducted at 1, 3, and 6 MCA using the Ages and Stages Questionnaire, the third edition (ASQ-3). Spearman correlation, a generalized linear mixed model (GLMM), and permutational multivariate analysis of variance (PERMANOVA) analysis were used to horizontally and prospectively explore the associations between gut microbial and ASQ-3 dimension scores at each time point. The GLMM showed no significant associations between the alpha diversity and neurodevelopmental trajectory from 1 to 6 MCA. The beta diversity was significantly associated with gross motor scores at 1, 3, and 6 MCA (R2 = 0.067, p = 0.001; R2 = 0.039, p = 0.020; R2 = 0.031, p = 0.047); communication scores at 3 MCA (R2 = 0.030, p = 0.040); and fine motor scores at 6 MCA (R2 = 0.035, p = 0.022). After adjusting for covariates, the GLMM showed that the relative abundance of Klebsiella was negatively associated with gross motor score trajectory from 1 to 6 MCA (β = - 1.449; 95% CI, - 2.275 to - 0.572; p = 0.001), while the relative abundance of Lactobacillus displayed a positive association (β = 1.421; 95% CI, 0.139 to 2.702; p = 0.030). Moreover, the relative abundance of Streptococcus was negatively associated with fine motor trajectory from 1 to 6 MCA (β = - 1.669; 95% CI, - 3.305 to - 0.033; p = 0.046). CONCLUSION Our results suggest a possible association between the neonatal gut microbial diversity; the relative abundance of Klebsiella, Streptococcus, and Lactobacillus; and neurodevelopment from 1 to 6 MCA. In the future, clinical staff can focus on the window period of gut microbiota colonization, and implement probiotics targeted at the dominant genera to improve the neurodevelopment of preterm infants. WHAT IS KNOWN • In the fields of biology and medicine, current studies suggest that gut microbiota may play an important role in the critical window period of neurodevelopment through the gut-brain axis pathway. • Extensive preclinical research has implied the vital role of the initial gut colonization in the long-term neurodevelopment of children. WHAT IS NEW • The early-life gut microbiota was associated with neurodevelopment in preterm infants within 6 months of corrected age (MCA).

Abstract
BACKGROUND A Suitable environment and proper child nutrition are paramount to a child's physical and mental development. Different environmental factors contribute to proper child development. Breast milk is an important source of nutrition during the early years of life and contains essential nutrients that are the building blocks for growth and development. OBJECTIVE To assess the association between the duration of breastfeeding and fine motor development among children aged 20 to 24 months living in Butajira, southern Ethiopia. METHOD Community-based case-control study design was employed among mother-child dyads of children aged 20 to 24 months in Butajira Southern Ethiopia. Children were screened for fine motor delay using the Denver II developmental screening and identified as cases and controls. A repeated visit was done to gather the rest of the information and 332 samples, 83 cases, and 249 controls were available and assessed. Epi-data version 4.4.2.1 software was used to prepare a data entry template, which was later exported to and analyzed using STATA version 14 statistical software. Finally, a Multivariable logistic regression model was used to adjust for confounders and estimate the independent effect of breastfeeding duration on fine motor development. RESULT We didn't find a significant association between the duration of breastfeeding from 21 to 24 months and fine motor delay compared to children who were breastfed less than 18 months[AOR: 0.86, 95% CI: (0.36, 2.05)]. Children who have mothers > 35 years of age were 78% less likely than children who had mothers younger than 25 years, Children who had mothers in secondary school and above were 77% less likely than mothers who didn't have formal education, Females were 1.86 times more likely than males, and Children who scored 20-29 on the Home score were 51% less likely than Children who scored < 20 to have fine motor delay. CONCLUSION Duration of breastfeeding was not significantly associated with fine motor delay for children aged 20 to 24 months old. The age of the mother, the educational status of the mother, being female, and Home score were identified to have a significant association with fine motor delay. Improving the educational status and empowerment of women is essential. Further work should be done on avoiding gender differences starting from a young age and creating a conducive environment for child development is crucial.

Abstract
PURPOSE To explore the lived experiences of the caregivers of children with developmental delay (DD) on the remote island of Kinmen, Taiwan. DESIGN AND METHODS This descriptive phenomenological study included 14 caregivers of 16 children with DD recruited from Kinmen, Taiwan. Data were collected from September 2020 to February 2021 with face-to-face semi-structured interviews, which were transcribed verbatim and analyzed using thematic analysis. RESULTS Twelve caregivers were mothers; there was one father and one grandmother. Their mean age was 37.93 ± 5.17 years. The mean age of the children was 3.90 ± 1.49 years; 11 were male (69%). As we began our study, the COVID-19 pandemic occurred, which influenced two of the three themes: (1) focusing on their child's delayed development, which involved seeking a diagnosis and blaming themselves; (2) facing barriers to caring a child with DD on a remote island, which included ostracization of their child and limited off-island medical resources, especially during COVID-19; and (3) maintaining a healthy life balance, which involved protecting their child from physical or spiritual harm, including exposure to COVID-19, and reflecting on their strengths. CONCLUSIONS Our findings highlight the challenges of caring for a child with DD in the Kinmen islands of Taiwan, and the impact of the COVID-19 pandemic. PRACTICAL IMPLICATIONS Healthcare professionals are encouraged to provide caregivers of children with DD living in remote, island communities an opportunity to share their caregiving experiences and provide strategies for obtaining medical care, which could help reduce caregiver burden.

Abstract
BACKGROUND There are rising numbers of infants entering out-of-home care due to child protection concerns. Research has found that infants entering care are at higher risk of developmental vulnerability and poor health problems. OBJECTIVES To determine the prevalence of developmental vulnerability for children who entered care as infants, and the extent and likelihood of service provision in relation to their developmental vulnerability. PARTICIPANTS AND SETTING This study includes children who entered care before the age of 1 year for the first time between May 2010 and October 2011 in New South Wales, Australia, and who received final Children's Court care and protection orders by 30 April 2013. METHODS This is a prospective cohort study using interview data from the Pathways of Care Longitudinal Study (POCLS) as well as linked administrative child protection and health data. This study used standardised assessments (Age and Stages Questionnaire and the Brief Infant Toddler Social Emotional Assessment) included in the POCLS. Simple and multiple logistic regression analysis was conducted to investigate the likelihood of infants receiving professional services for developmental delays since placement. FINDINGS A high proportion of children who entered care as infants were identified as developmentally vulnerable through health indicators (36 %) and standardised assessments (70 %). Only 17 % of infants in care received services for developmental delay, with 20 % and 15 % of those identified as developmentally vulnerable through standardised assessments and health-related variables receiving services, respectively. CONCLUSIONS The findings point to the importance of developmental assessment of infants in care and the identification of developmental vulnerability and delays. The provision of early intervention services is essential for this group of high-risk infants and will be important in optimising their health, as well as social and emotional outcomes.

Abstract
PURPOSE Developmental assessment is part of a comprehensive autism evaluation. During in-person evaluations, developmental assessment is completed via direct testing by an examiner. In telehealth evaluations, developmental assessment relies on caregiver-report instruments. This study examined correspondence between caregiver report and direct testing of developmental skills. METHODS Participants were 93 children, aged 18-42 months, undergoing evaluation for possible autism spectrum disorder (ASD). Caregivers were interviewed with the Developmental Profile, 4th edition (DP-4) via telehealth platform and children were tested in person 2-4 weeks later using the Mullen Scales of Early Learning (MSEL). RESULTS Correlations between the DP-4 and MSEL were high (ranging from 0.50 to 0.82) across standard scores, age equivalents, and functional categories, as well as across individual subtests and overall composite scores. CONCLUSION The high convergent validity found in this study suggests that the DP-4 provides a suitable proxy for direct developmental testing using the MSEL in the context of telehealth evaluations for ASD in young children, delivering a good estimate of both developmental functioning and presence of delays. TRIAL REGISTRATION Data were obtained from registered clinical trial NCT05047224, date of registration 2021-09-07.

Abstract
OBJECTIVE This study investigated the clinical, imaging, and electroencephalogram (EEG) characteristics of methylmalonic acidemia (MMA) with nervous system damage as the primary manifestation. METHODS From January 2017 to November 2022, patients with nervous system injury as the main clinical manifestation, diagnosed with methylmalonic acidemia by metabolic and genetic testing, were enrolled and analyzed. Their clinical, imaging, and electroencephalogram data were analyzed. RESULTS A total of 18 patients were enrolled, including 15 males and 3 females. The clinical symptoms were convulsions, poor feeding, growth retardation, disorder of consciousness, developmental delay, hypotonia, and blood system changes. There were 6 cases (33%) of hydrocephalus, 9 (50%) of extracerebral space widened, 5 (27%) of corpus callosum thinning, 3 (17%) of ventricular dilation, 3 (17%) of abnormal signals in the brain parenchyma (frontal lobe, basal ganglia region, and brain stem), and 3 (17%) of abnormal signals in the lateral paraventricular. In addition, there were 3 cases (17%) of cerebral white matter atrophy and 1 (5%) of cytotoxic edema in the basal ganglia and cerebral peduncle. EEG data displayed 2 cases (11%) of hypsarrhythmia, 3 (17%) of voltage reduction, 12(67%) of abnormal discharge, 13 (72%) of abnormal sleep physiological waves or abnormal sleep structure, 1 (5%) of immature (delayed) EEG development, and 8 (44%) of slow background. There were 2 cases (11%) of spasms, 1 (5%) of atonic seizures, and 1 (5%) of myoclonic seizures. There were 16 patients (89%) with hyperhomocysteinemia. During follow-up, 1 patient was lost to follow-up, and 1 died. In total, 87.5% (14/16) of the children had varying developmental delays. EEG was re-examined in 11 cases, of which 8 were normal, and 3 were abnormal. Treatments included intramuscular injections of vitamin B12, L-carnitine, betaine, folic acid, and oral antiepileptic therapy. Acute treatment included anti-infective, blood transfusion, fluid replacement, and correcting acidosis. The other treatments included low-protein diets and special formula milk powder. CONCLUSION Methylmalonic acidemia can affect the central nervous system, leading to structural changes or abnormal signals on brain MRI. Metabolic screening and genetic testing help clarify the diagnosis. EEG can reflect changes in brain waves during the acute phase.

Abstract
OBJECTIVE Aicardi Goutières Syndrome (AGS) is a genetic interferonopathy associated with multisystemic heterogeneous disease and neurologic dysfunction. AGS includes a broad phenotypic spectrum which is only partially explained by genotype. To better characterize this variability, we will perform a systematic analysis of phenotypic variability in familial cases of AGS. METHODS Among thirteen families, twenty-six siblings diagnosed with AGS were identified from the Myelin Disorders and Biorepository Project (MDBP) at the Children's Hospital of Philadelphia. Data were collected on the age of onset, genotype, neurologic impairment, and systemic complications. Neurologic impairment was assessed by a disease-specific scale (AGS Severity Scale) at the last available clinical encounter (range: 0-11 representing severe - attenuated phenotypes). The concordance of clinical severity within sibling pairs was categorized based on the difference in AGS Scale (discordant defined as >2-unit difference). The severity classifications were compared between sibling sets and by genotype. RESULTS Five genotypes were represented: TREX1 (n = 4 subjects), RNASEH2B (n = 8), SAMHD1 (n = 8) ADAR1 (n = 4), and IFIH1 (n = 2). The older sibling was diagnosed later relative to the younger affected sibling (median age 7.32 years [IQR = 14.1] compared to 1.54 years [IQR = 10.3]). Common presenting neurologic symptoms were tone abnormalities (n = 10/26) and gross motor dysfunction (n = 9/26). Common early systemic complications included dysphagia and chilblains. The overall cohort median AGS severity score at the last encounter was 8, while subjects presenting with symptoms before one year had a median score of 5. The TREX1 cohort presented at the youngest age and with the most severe phenotype on average. AGS scores were discordant for 5 of 13 sibling pairs, most commonly in the SAMHD1 pairs. Microcephaly, feeding tube placement, seizures and earlier onset sibling were associated with lower AGS scores (respectively, Wilcoxon rank sum: p = 0.0001, p < 0.0001, p = 0.0426, and Wilcoxon signed rank: p = 0.0239). CONCLUSIONS In this systematic analysis of phenotypic variability in familial cases, we found discordance between siblings affected by AGS. Our results underscore the heterogeneity of AGS and suggest factors beyond AGS genotype may affect phenotype. Understanding the critical variables associated with disease onset and severity can guide future therapeutic interventions and clinical monitoring. This report reinforces the need for further studies to uncover potential factors to better understand this phenotypic variability, and consequently identify potential targets for interventions in attempt to change the natural history of the disease.

Abstract
OBJECTIVE This study aimed to examine the long-term influence of having a child at risk of different developmental delays (communication, mobility, self-care, relating, learning, coping, or behaving) on parental labor force participation as the child grows. METHOD A retrospective cohort was conducted using data from the Longitudinal Study of Australian Children survey, Waves 1-8 covering birth to 15 years of age of children. Multivariable logistic regressions were used to explore the odds ratio of mothers being out of the labor force at different children's ages. Cox proportional hazards models were utilized to identify the 'risk' of mothers returning to the workforce after leaving. All models were adjusted for the mother's age, education attainment, and employment status at time of birth, as well as marital status at the current wave. RESULTS There were 5,107 records of children, and 266 of them were at risk of any developmental delays at age 4-5 years. This sample represents 243, 026 children born in Australia in 2003/04. After adjusting for potential confounders, mothers of children at risk of each type of developmental delay (except mobility and self-care) had greater odds of being out of, and not returning to the labor force from children aged 2-3 to 14-15 years, when compared to mothers of children who are not at risk of developmental delays. Similar differences were found for fathers but were distinctly small and with narrower fluctuations, compared to mothers. CONCLUSION Policies and programs funded by the government are greatly needed to support the mothers of children at risk of developmental delays.

Abstract
BACKGROUND Pitt-Hopkins syndrome (PTHS) is a neurodevelopmental disorder that remains underdiagnosed and its clinical presentations and mutation profiles in a diverse population are yet to be evaluated. This retrospective study aims to investigate the clinical and genetic characteristics of Chinese patients with PTHS. METHODS The clinical, biochemical, genetic, therapeutic, and follow-up data of 47 pediatric patients diagnosed with PTHS between 2018 and 2021 were retrospectively analyzed. RESULTS The Chinese PTHS patients presented with specific facial features and exhibited global developmental delay of wide severity range. The locus heterogeneity of the TCF4 gene in the patients was highlighted, emphasizing the significance of genetic studies for accurate diagnosis, albeit no significant correlations between genotype and phenotype were observed in this cohort. The study also reports the outcomes of patients who underwent therapeutic interventions, such as ketogenic diets and biomedical interventions. CONCLUSIONS The findings of this retrospective analysis expand the phenotypic and molecular spectra of PTHS patients. The study underscores the need for a long-term prospective follow-up study to assess potential therapeutic interventions.

Abstract
BACKGROUND The purpose of surgeries performed for congenital anomalies in children is to increase the survival rates and provide a developmental comparison to that of their peers. AIM The objective of this study was to investigate the development of children following surgery for congenital anomalies and the risk factors affecting their development. METHODS Our study included 33 children who underwent surgery for gastrointestinal anomalies in our clinic between 2011 and 2016, and did not have any syndrome, chromosomal abnormality, or additional abnormality. Developmental levels were evaluated using the Ages and Stages Questionnaire (ASQ) and the ASQ: Social-Emotional (ASQ: SE) scales adapted for the use on Turkish children. Data on patient history were obtained retrospectively from patient files. RESULTS The study included 33 patients, including 11 with esophageal atresia, 6 with intestinal atresia, 11 with anorectal malformation, and 5 with Hirschsprung's disease. Developmental delay was found in the ASQ of 72.7% of the patients and the ASQ: SE tool was 27% of the patients. The rate of patients with scores below the threshold from each parameter of ASQ was higher than that of the normal population (p < 0.05). Development delay was detected using the ASQ scale in 100% of those with microcephaly at birth, in 91% of premature infants born between 1500 and 2500 g, and in 83.3% of those with low birth weight to gestational age. CONCLUSIONS In children who underwent surgery due to congenital anomalies, an evaluation through developmental tests, a post-surgical follow-up process, and a referral to the relevant disciplines when necessary may increase the success of surgery as well as increase the life quality of the patient.

Abstract
OBJECTIVES To determine: i) seizure recurrence; ii) developmental disability; iii) co-morbidities and risk factors in self-limited familial neonatal and/or infantile epilepsy (SeLFE) in a multigenerational study. METHODS Families were retrospectively recruited from epilepsy databases (2021-2022) in 2 paediatric hospitals, Sydney, Australia. Eligible families had 2 first degree relatives with seizures and underwent genetic testing. Demographics/clinical data were collected from interviews and medical records. Vineland Adaptive Behaviour Scales-Third Edition measured adaptive function. RESULTS Fifteen families participated. Fourteen had a genetic diagnosis (93%): 11 pathogenic; PRRT2 (n=4), KCNQ2 (n=3), SCN2A (n=4), 3 likely pathogenic; KCNQ2 (n=1), SCN8A (n=2). Seizures affected 73 individuals (ages 1-76 years); 30 children and 20 adults had in-depth phenotyping. Ten of 50 individuals (20%) had seizure recurrence, aged 8-65 years. Median time from last neonatal/infantile seizure was 11.8/12.8 years. Predictors of recurrence were high seizure number (p=0.05) and longer treatment duration (p=0.03). Seven children had global developmental delay (GDD): mild (n=4), moderate (n=1) and severe (n=2). Vineland-3 identified 3 had low-average and 3 had mild-moderately impaired functioning. The majority (82%) were average. GDD was associated with older age at last seizure (p=0.03), longer epilepsy duration (p=0.02), and higher number of anti-seizure medications (p=0.05). Four children had speech delay, 5 (10%) had Autism Spectrum Disorder. Paroxysmal kinesiogenic dyskinesia (n=5) occurred in 4 families and hemiplegic migraine (n=8) in 3 families. CONCLUSIONS Individuals with SeLFE have a small risk of recurrent seizures (20%) and neurodevelopmental disability. Significant predictors are higher seizure number and longer epilepsy duration. Developmental surveillance is imperative.

Abstract
PURPOSE We sought to delineate a multisystem disorder caused by recessive cysteine-rich with epidermal growth factor-like domains 1 (CRELD1) gene variants. METHODS The impact of CRELD1 variants was characterized through an international collaboration utilizing next-generation DNA sequencing, gene knockdown, and protein overexpression in Xenopus tropicalis, and in vitro analysis of patient immune cells. RESULTS Biallelic variants in CRELD1 were found in 18 participants from 14 families. Affected individuals displayed an array of phenotypes involving developmental delay, early-onset epilepsy, and hypotonia, with about half demonstrating cardiac arrhythmias and some experiencing recurrent infections. Most harbored a frameshift in trans with a missense allele, with 1 recurrent variant, p.(Cys192Tyr), identified in 10 families. X tropicalis tadpoles with creld1 knockdown displayed developmental defects along with increased susceptibility to induced seizures compared with controls. Additionally, human CRELD1 harboring missense variants from affected individuals had reduced protein function, indicated by a diminished ability to induce craniofacial defects when overexpressed in X tropicalis. Finally, baseline analyses of peripheral blood mononuclear cells showed similar proportions of immune cell subtypes in patients compared with healthy donors. CONCLUSION This patient cohort, combined with experimental data, provide evidence of a multisystem clinical syndrome mediated by recessive variants in CRELD1.

Abstract
BACKGROUND Developmental delay (DD) occurs when children fail to reach developmental milestones in comparison to peers of the same age range. However, there are no valuable biomarkers for the early diagnosis of DD. Since there is no specific marker for screening the disease, we evaluated plasma NSE, TNF-α and sIL2-Rα as potential markers for this purpose. METHODS In this cross-sectional randomized case-control study, a total of 174 DD patients and 49 matched elderly controls aged between 2 months and 60 months were recruited. A sensitive enzyme-linked immunosorbent assay and an immunoradiometric assay were used to evaluate the levels of plasma IL-1, IL-6, IL-8, IL-10, sIL2-Rα, TNF-α, and NSE. Statistical analyses using t test, χ2, ANOVA, ROC curves and binary logistic regression models were performed. RESULTS In comparison to the control group, the DD group had greater levels of NSE, TNF-α, and sIL2-Rα(p < 0.05). In the binary logistic regression analysis of DD, NSE had an odds ratio (OR) of 1.783 (95 % CI 1.297 to 2.451, p = 0.000), indicating that NSE was an independent risk factor for DD. The plasma TNF-α level was positively correlated with plasma NSE and sIL2-Rα levels in the DD group (r = 0.366 and 0.433, respectively), and the DQ score and plasma sIL2-Rα level in the DD group were positively correlated. The ROC curve revealed that the respective areas under the NSE, TNF-α, and sIL2-Rα ROC curves were 0.9797, 0.9365, and 0.8533, respectively. Moreover, a significant increase in AUC was observed using combined ROC curve analysis. CONCLUSIONS Children with DD have significantly altered plasma concentrations of sIL2-Rα, NSE, and TNF-α. NSE, TNF-α and sIL2-Rα can be used as DD blood biomarkers. This information may be helpful in early diagnosis and intervention.

Abstract
INTRODUCTION The mechanism of occurrence and complications of asphyxia change in the treatment process and the future prognosis of newborns. One of the discussed mechanisms is the disruption of oxidants to anti-oxidants balance. Therefore, the current study was conducted aiming to systematically review and conduct a meta-analysis on the diagnosis and prognosis of prenatal asphyxia based on oxidant-antioxidant balance. METHODS A comprehensive electronic search was conducted using PubMed, Cochrane Library, Scopus, and Web of Science databases, up to February 2023 to identify relevant studies examining the association between Prooxidant anti-oxidant balance (PAB) and Malondialdehyde 1 levels with the risk of prenatal asphyxia. Only English studies were incorporated. The search terms used included Asphyxia, Diagnosis, Prognosis, Newborns, Prenatal, Oxidant antioxidant balance, and oxidative stress. A total of 13 studies were retrieved. Data regarding the standard mean difference (SMD) were collected, and a pooled SMD with 95%CI was calculated using a random-effect model to determine the strength of the relationship. Furthermore, the risk of publication bias was assessed through funnel plot and Egger's linear regression tests. Inclusion criteria was 1) The studies conducted on neonates, diagnosis and outcomes of prenatal asphyxia, oxidants and antioxidants were included. Research conducted on adults or on animals or review articles, and articles in which only their abstracts were available were excluded. The quality of the reported studies was also assessed. RESULTS Out of 980 searched articles, 13 articles (10 prospective articles and 3 cross-sectional articles) were studied. An increase in antioxidant enzymes (Glutathione peroxidase (GSH-Px), catalase (CAT) and Plasma superoxide dismutase (SOD)) cannot be dealt with excessive oxidants produced in the body (Plasma and cerebrospinal fluid levels of Malondialdehyde (MDA), free radical products (F8-isoprostane and MDA), saturated fatty acids and % CoQ-10). Prooxidant anti-oxidant balance (PAB) levels among neonates who had asphyxia were announced to be two times higher than normal newborns. PAB values in neonates with asphyxia, who had adverse prognosis, were about three times higher than those with favorable prognosis. The sensitivity of PAB in predicting the prognosis of neonates with asphyxia was reported 83- 89% and its specificity was 71- 92%. The pooled SMD analysis revealed a significant association between PAB and MDA levels with the risk of prenatal asphyxia both overall (SMD = 1.447, 95%CI: 0.961-1.934, P < 0.001), as well as separately in subgroups of PAB (SMD = 1.134, 95%CI: 0.623-1.644, P < 0.001) and MDA (SMD = 1.910, 95%CI: 0.916-2.903, P < 0.001). CONCLUSION Our meta-analysis findings revealed the potential of evaluating antioxidant enzymes and oxidant agents, as well as assessing the balance between them (PAB), in diagnosing and predicting the prognosis of neonatal asphyxia. The limitations of the present study included not having access to all related complete articles, lack of quality and usability in reports of some articles, and the different diagnostic methods of prenatal asphyxia in different studies.

Abstract
BACKGROUND Identifying the underlying etiology of developmental delay/intellectual disability (DD/ID) is challenging but important. The genetic diagnosis of unexplained DD/ID helps in the treatment and prognosis of the disability in patients. In this study, we reported our experience of using whole exome sequencing (WES) of children with unexplained DD/ID. METHODS We conducted a retrospective analysis of WES results of children under 19 years of age with unexplained DD/ID between January 2020 and December 2021. The demographic data of all patients and variants identified through WES were evaluated. Furthermore, we evaluated the clinical characteristics that influenced the identification of genetic causes. RESULTS Forty-one patients with DD/ID were included, of whom 21 (51.2 %) were male. The average age at symptom onset was 1.6 ± 1.3 years, and the duration from symptom onset to diagnosis was 3.1 ± 3.7 years. Hypotonia was the most common symptom (17 patients, 41.5 %), and epilepsy was confirmed in 10 patients (24.4 %). Twenty-two pathogenic/likely pathogenic variants were identified in 20 patients, and three variants of uncertain significance were identified in three patients. Family-based trio Sanger sequencing for candidate variants of 12 families was conducted; 10 variants were de novo, one variant paternally inherited, and two variants compound heterozygous. The diagnostic yield of WES for DD/ID was 48.8 % and was significantly high in patients with an early onset of DD/ID and facial dysmorphism. In contrast, patients with autism spectrum disorder (ASD) were more likely to have negative WES results compared with others without ASD. CONCLUSION The diagnostic yield of WES was 48.8 %. We conclude that patients' characteristics, such as dysmorphic features and the age of symptom onset, can predict the likelihood that WES will identify a causal variant of a phenotype.

Abstract
NUDT2 is an enzyme important for maintaining the intracellular level of the diadenosine tetraphosphate (Ap4A). Bi-allelic loss of function variants in NUDT2 has recently been reported as a rare cause of intellectual disability (ID). Herein, we describe a Chinese girl with ID, attention deficit hyperactivity disorder (ADHD), and motor delays with abnormal walking posture and difficulty climbing stairs, who bears compound heterozygous variants c.34 C > T (p.R12*) and c.194T > G (p.I65R) in NUDT2. Homozygous variants c.34 C > T (p.R12*) or c.186del (p.A63Qfs*3) in NUDT2 were previously reported to cause ID. This is the first patient with ID due to compound heterozygous variants in NUDT2 and p.I65R is a novel missense variant. This study enriched the genotype and phenotype of NUDT2-related ID and supported the critical developmental involvement of NUDT2.

Abstract
Lissencephaly is a neurodevelopmental disorder characterized by a loss of brain surface convolutions caused by genetic variants that disrupt neuronal migration. However, the genetic origins of the disorder remain unidentified in nearly one-fifth of people with lissencephaly. Using whole-exome sequencing, we identified a de novo BAIAP2 variant, p.Arg29Trp, in an individual with lissencephaly with a posterior more severe than anterior (P>A) gradient, implicating BAIAP2 as a potential lissencephaly gene. Spatial transcriptome analysis in the developing mouse cortex revealed that Baiap2 is expressed in the cortical plate and intermediate zone in an anterior low to posterior high gradient. We next used in utero electroporation to explore the effects of the Baiap2 variant in the developing mouse cortex. We found that Baiap2 knockdown caused abnormalities in neuronal migration, morphogenesis and differentiation. Expression of the p.Arg29Trp variant failed to rescue the migration defect, suggesting a loss-of-function effect. Mechanistically, the variant interfered with the ability of BAIAP2 to localize to the cell membrane. These results suggest that the functions of BAIAP2 in the cytoskeleton, cell morphogenesis and migration are important for cortical development and for the pathogenesis of lissencephaly in humans.

Abstract
Very preterm (VPT; < 33 weeks' gestation) toddlers screening positively for autism spectrum conditions (ASC) may display heterogenous neurodevelopmental trajectories. Here we studied neonatal brain volumes and childhood ASC traits evaluated with the Social Responsiveness Scale (SRS-2) in VPT-born toddlers (N = 371; median age 20.17 months) sub-divided into three groups based on their Modified-Checklist for Autism in Toddlers scores. These were: those screening positively failing at least 2 critical items (critical-positive); failing any 3 items, but less than 2 critical items (non-critical-positive); and screening negatively. Critical-positive scorers had smaller neonatal cerebellar volumes compared to non-critical-positive and negative scorers. However, both positive screening groups exhibited higher childhood ASC traits compared to the negative screening group, suggesting distinct aetiological trajectories associated with ASC outcomes.

Abstract
BACKGROUND The PACS gene family has been demonstrated to be related to intracellular vesicular trafficking. The phenotypic manifestations caused by the pathogenic variants of PACS include epilepsy, intellectual disability/developmental delay, and malformations, such as facial abnormalities. METHODS We identified seven new cases with pathogenic or likely pathogenic PACS variants using next-generation sequencing. Detailed information obtained from these patients was analyzed along with that obtained from previously reported patients. RESULTS With the inclusion of the newly diagnosed cases in this study, 103 cases with PACS gene family-related neurological diseases were reported, of which 43 were PACS2-related cases and the remaining were PACS1-related cases. Most patients had seizures, which have been reported to be effectively controlled by several types of anti-seizure medications (ASMs). The most efficacious and frequently prescribed ASMs included sodium valproate (43.3%, 13/30), oxcarbazepine/carbamazepine (26.7%, 8/30), and levetiracetam (20%, 6/30). Almost all patients had intellectual disability/developmental delay. The most common pathogenic missense variants were PACS1 p. Arg203Trp and PACS2 p.Glu209Lys. In addition, we report a patient carrying a likely pathogenic copy number variation (CNV) (de novo heterozygous deletion of chr14:105821380-106107443, 286 kilobase, destroyed part of the furin-binding region domain and the protein structure after it) with more severe and refractory late-onset epilepsy. CONCLUSIONS The clinical phenotypes of the different PACS heterozygous missense variants were similar. The pathogenic variant sites of PACS1 and PACS2 were quite limited but located in different regions. A CNV destroying part of the PACS2 gene might also be pathogenic. These findings may provide an important clue for further functional studies on the pathogenic mechanism of neurological disorders related to the PACS gene family. Video Abstract (MP4 65767 kb).

Abstract
PURPOSE This study was designed to assess the developmental outcomes among preschool-aged children and its associated factors in Palestine. METHODS A cross-sectional, descriptive-correlational design involved a representative sample of preschool-aged children from kindergarten in Ramallah governorate. Data were collected using the Ages and Stages Questionnaire, Arabic version-3. Associations between developmental delay (DD), parent, child and family characteristics were analyzed utilizing SPSS-25 version. RESULTS A total of 249 preschoolers participated in the study. The overall rate of children with Global Developmental Delay (GDD) was 23.7%. The most prevalent DD were in gross motor, personal social, and fine motor skills (25.3%, 17.7%, and 16.5%, respectively). Binary logistic regression analysis revealed that the male gender of a child (OR = 2.66, 95% CI [1.37, 5.19]), the mother's part-time work (OR = 6.01, 95% CI [1.68, 21.52]), low family income (OR = 3.67, 95% CI [1.05, 12.73]), and families with three or more children (OR = 1.43, 95% CI [1.15, 1.781]) were statistically significant independent predictors of GDD. CONCLUSION The study findings revealed higher rate of DD among preschoolers in Palestine than regional areas, especially in gross motor, fine motor, and personal social skills, which has consequences for both national and global health. According to the results, factors related to the child, the mother and the family are associated with the cumulative risk of preschoolers having DD. IMPLICATIONS It is a crucial role for pediatric nurses to detect DD early and its related risk factors through screening programs to limit the burden of problems in childhood and later adulthood.

Abstract
BACKGROUND Although the literature suggests a negative association between early childhood development (ECD) and violent disciplinary measures, little is known about the gradient of this relationship. OBJECTIVE This study examined the gradient of the relationship between the number and types of child discipline practices at home and the ECD of children aged from 36-to-59 months. PARTICIPANTS AND SETTING The study used nationally representative data from the Multiple Indicator Cluster Survey Bangladesh 2019. METHODS We analysed secondary data using multivariable logistic regression to examine the relationship between child discipline practices and ECD. The gradients were measured using three sets of summative indexes of disciplinary practices and psychometric approach to the physical, literacy-numeracy, learning and social-emotional domains of ECD. RESULTS About 94 % of children had at least one of the eight violent disciplinary measures during the month preceding the survey. Approximately three-quarters of the children were on track in their ECD. The probability that children were on track in ECD significantly increased with non-violent disciplinary practices and decreased with violent disciplinary practices used. For one unit increase in the overall violent disciplinary index, the odds of children being on track in their ECD was reduced by 12 %, and the reduction was significant (adjusted odds ratio = 0.88; 95%CI: 0.86-0.91). CONCLUSIONS Children who had experienced several forms of violent disciplinary measures were more likely than those who did not to be delayed in their ECD. Banning violent punishments in all settings and positive parenting programs are recommended.

Abstract
The syndrome of megalencephaly, mega corpus callosum (MEG-MegaCC) accompanied by complete lack of motor development is a rare condition with only few sporadic cases having been reported in the literature. In this paper, we describe a child from non-consanguineous parents presenting with MegaCC, psychomotor retardation, and language impairment linked to MEG-MegaCC syndrome. Genetic analysis, radiological findings, and detailed neurological phenotype of MEG-MegaCC syndrome with its overlapping syndromes would allow for a better classification of the disease spectrum.

Abstract
BACKGROUND Infants with complex congenital heart disease are at increased risk of impaired fetal brain growth, brain injury, and developmental impairments. The General Movement Assessment (GMA) is a valid and reliable tool to predict cerebral palsy (CP), especially in preterm infants. Predictive properties of the GMA in infants with complex congenital heart disease (CCHD) are unknown. AIM To evaluate predictive properties of the GMA to predict developmental outcomes, including cerebral palsy (CP), at 18-months corrected age (CA) in children with CCHD undergoing heart surgery in the first month of life. METHODS A prospective cohort of 56 infants with CCHD (35 males, 21 females) was assessed with GMA at writhing age (0-6 weeks CA) and fidgety age (7-17 weeks CA) and the Bayley Scales of Infant Development at 18 months. GMA focused on markedly reduced GM-variation and complexity (definitely abnormal (DA) GM-complexity) and fidgety movements. Predictive values of GMA for specific cognitive, language and motor delay (composite scores <85th percentile) and general developmental delay (delay in all domains) were calculated at 18 months. RESULTS At fidgety age, all infants had fidgety movements and no child was diagnosed with CP. DA GM-complexity at fidgety age predicted general developmental delay at 18 months (71 % sensitivity, 90 % specificity), but predicted specific developmental delay less robustly. DA GM-complexity at writhing age did not predict developmental delay, nor did it improve prediction based on DA GM-complexity at fidgety age. CONCLUSIONS In infants with CCHD and fidgety movements, DA GM-complexity at fidgety age predicted general developmental delay.

Abstract
BACKGROUND Child psychomotor development and factors affecting it today is the subject of interest of many studies, in particular by the experts involved in the protection and improvement of children's health. There is limited evidence on developmental delay among under-five children in low-income countries like Ethiopia. The aim of this study was to assess gross motor developmental delay and associated factors among under-five children attending public health facilities of Dessie city, Ethiopia. METHODS Facility based cross sectional study design was used among under-five children attending under-five OPD in public health facilities of Dessie town from July 1, 2020 to August 15, 2021. A total of, 417 under-five children were systematically selected based on their average number of clients in a month. A pretested structured questionnaire was used for data collection, and data was entered into Epi-data 3.1 version and it was exported to STATA version 14 for analysis. Binary logistic regression analysis was used to identify factors associated with the outcome variable. Odds ratio with 95% confidence interval was used to show the strength and direction of association respectively and P-value less than 0.05 is used to declare statistical significance. RESULTS The overall proportion of gross motor developmental delay among under-five children attending health facilities of Dessie city, Ethiopia was 16.31%, 95% CI: (13.05, 20.19). Increased age of the child [AOR = 0.97, 95% CI: (0.96, 0.99)], increased gestational age during pregnancy [AOR = 0.47, 95% CI: (0.37, 0.65)], being male [AOR = 5.26, 95% CI: (1.76, 15.67)], having history of alcohol intake during pregnancy [AOR = 7.40, 95% CI: (2.36, 23.25)], taking iron during pregnancy [AOR = 0.04, 95% CI: (0.01, 0.15)], facing fetal and/or maternal complication [AOR = 4.98, 95% CI: (1.20, 20.62)], having instrumental delivery [AOR = 9.78, 95% CI: (2.48, 38.60)] were significantly associated with gross motor developmental delay. CONCLUSIONS The gross motor developmental delay among under-five children was higher as compared to other literatures. This study indicated that, age and sex of the child, iron and alcohol intake during pregnancy, gestational age, mode of delivery and any complication to her and or her neonate were independent variables which showed statistical significant association. The physicians should advise mothers to take iron-folic acid supplement properly and to avoid intake of alcohol during pregnancy. In addition, they should focus on those mothers who faced any complication to her and/or her neonate and better to discourage instrumental delivery unless there are no other options.

Abstract
Mutations in PTHLH (PTH-like hormone), cause brachydactyly type E (BDE) characterized by shortening of metacarpals, metatarsals and/or phalanges with short stature. In this report we describe three siblings and their mother with a novel heterozygous mutation c.25 T > C, p.Trp9Arg in exon 2 of the PTHLH gene. Beside the known clinical features of PTHLH mutations all had a delay in speech and language development, unknown if this is related to the mutation. Patients with PTHLH mutation may have a variable phenotypic presentation.

Abstract
BACKGROUND Neurodevelopmental disorders (NDDs) have diverse phenotypes. Their genetic diagnoses are often challenged by difficulties of targeting causative genes due to heterogeneous genetic etiologies. The objective of this study was to perform genetic diagnosis of children with NDDs using whole genome sequencing. METHODS This study included 78 pediatric patients with NDDs and their 152 family members for whole genome sequencing (WGS). All cases except one were families with at least two members. Seventy-five patients had previously undergone other genetic tests besides WGS. Detected variants were classified according to the guidelines of the American College of Medical Genetics and Genomics. RESULTS Among 78 probands, 26 patients were genetically diagnosed with NDDs through WGS, showing a diagnostic rate of 33.3%. Of them, 22 cases had de novo variants (DNVs) identified through trio analysis. Of these DNVs, half were novel variants. Three structural variants, including a multiexon deletion, a contiguous gene deletion involving 13 Mb, and a retrotransposon insertion, were revealed by WGS. All cases except one had defects in different genes, consistent with the phenotypically diverse nature of NDDs. In addition, three patients were inconclusive, two of them had one likely pathogenic variant in a gene associated with autosomal recessive disease and the other one had no clinical phenotypes associated with the detected DNV. CONCLUSIONS Our experience demonstrates the advantage of WGS in the diagnosis of NDDs, including detection of copy number variations and also the advantage of trio sequencing for interpretation of DNVs.

Abstract
In this study, we examined imitation performance, visual attention, and the relationship between imitation and visual attention of children with autism, developmental delay (DD), and typically developing (TD) children. The study findings revealed that children with autism and DD imitated less than TD children in all imitation tasks. Results also showed that children with autism spent less time looking at the model's face and movement area and more time looking at the external area. Lastly, the relationship between imitation and visual attention separated the study groups. The findings of the study provided new evidence that visual attention to movement area in children with autism was positively related to imitation performance in non-meaningful gestures.

Abstract
BACKGROUND The TBL1XR1 gene encodes the protein transducin-beta-like 1 receptor1, widely distributed in the pituitary, hypothalamus, white and brown adipose tissue, muscle, and liver. Current evidence suggests that heterozygous TBL1XR1 pathogenic variants can lead to a wide spectrum of phenotypes. This study aims to reveal the clinical phenotype and genetic profiles of de novo TBL1XR1 variations and summarize the relevant clinical and genetic features. METHODS We analyzed four new cases harboring de novo TBL1XR1 variants and reviewed all reported cases. RESULTS All probands suffered from global developmental delay. Moreover, patient 1 exhibited susceptibility to startle, patient 2 had hypovitaminosis D, short stature and hyponatremia, and patients 3 and 4 both presented with ASD (Autism spectrum disorder) and short stature. They all had a de novo TBL1XR1 variant (NM_024665.7), c.1184A > G (p.Tyr395Cys), c.1108G > A (p.Asp370Asn), c.1047 + 1G > C, and c.1097C > T (p.Ser366Phe) respectively. In addition, pooled analysis of 51 cases showed that they had speech impairment (38/39), intellectual developmental disorder (28/28), global developmental delay (42/42), and hypotonia (24/27), and some of them had epilepsy (10/22), ASD (13/25), and developmental regression (4/13). CONCLUSIONS We report four new patients with de novo TBL1XR1 variants and provide a comprehensive overview of 47 previously reported individuals with TBL1XR1 variants, enriching the genotypic and phenotypic spectrum of TBL1XR1-related disease. This report further validates the pathogenicity de novo TBL1XR1 variants.

Abstract
The transmembrane 63 (TMEM63) family of proteins are originally identified as homologs of the osmosensitive calcium-permeable (OSCA) channels in plants. Mechanosensitivity of OSCA and TMEM63 proteins are recently demonstrated in addition to their proposed activation mechanism by hyper/hypo-osmolarity. TMEM63 proteins exist in all animals, with a single member in Drosophila (TMEM63) and three members in mammals (TMEM63 A/B/C). In humans, monoallelic variants of TMEM63A have been reported to cause transient hypomyelination during infancy, or severe hypomyelination and global developmental delay. Heterozygous variants of TMEM63B are found in patients with intellectual disability and abnormal motor function and brain morphology. Biallelic variants of TMEM63C are associated with hereditary spastic paraplegias accompanied by mild or no intellectual disability. Physiological functions of TMEM63 proteins clearly recognized so far include detecting food grittiness and environmental humidity in Drosophila, and supporting hearing in mice by regulating survival of cochlear hair cells. In this review, we summarize current knowledge about the activation mechanisms and biological functions of TMEM63 channels, and provide a concise reference for researchers interested in investigating more physiological and pathogenic roles of this family of proteins with ubiquitous expression in the body.

Abstract
BACKGROUND Joubert syndrome (JS) is a rare genetically heterogeneous primary ciliopathy characterized by a pathognomonic cerebellar and brainstem malformation, the "molar tooth sign", and variable organ involvement (such as eye, kidney, liver, and skeleton). Here, we present a case of JS in a Chinese boy. CASE PRESENTATION An 11-year-old Chinese boy presented with neonatal asphyxiation and hypoxia, strabismus, subsequent developmental delay, ataxia and end-stage kidney disease (ESKD). Routine blood tests showed severe anemia, increasing blood urea nitrogen and creatinine, elevated parathyroid hormone, hypocalcemia, hypokalemia and metabolic acidosis. Urine tests showed mild proteinuria. Ultrasound showed two small kidneys. Brain magnetic resonance imaging (MRI) showed dysplasia of the cerebellar vermis and extension of the upper cerebellar feet with the "molar tooth sign". Genetic analysis showed novel compound heterozygous mutations in the RPGRIP1L gene [p.L447fs*7(p.Leu447fsTer7) and p.G908V (p.Gly908Val)]. CONCLUSION In the present study, we identified novel compound heterozygous mutations in the RPGRIP1L gene in a Chinese boy. The clinical and genetic findings of this study will expand the understanding of JS.

Abstract
PURPOSE This study reported the first case of Kohlschütter-Tönz syndrome (KTS) in China and reviewed the literature of the reported cases. METHODS This patient was registered at the Children's Hospital of Chongqing Medical University. The patient's symptoms and treatments were recorded in detail, and the patient was monitored for six years. We employed a combination of the following search terms and Boolean operators in our search strategy: Kohlschütter-Tönz syndrome, KTS, and ROGDI. These terms were carefully selected to capture a broad range of relevant publications in PubMed, Web of Science, WHO Global Health Library, and China National Knowledge Infrastructure, including synonyms, variations, and specific terms related to KTS. The pathogenicity of the variants was predicted using SpliceAI and MutationTaster, and the structures of the ROGDI mutations were constructed using I-TASSER. RESULTS This is the first case report of KTS in China. Our patient presented with epilepsy, global developmental delay, and amelogenesis imperfecta. A trio-WES revealed homozygous mutations in ROGDI (c.46-37_46-30del). The brain magnetic resonance imaging (MRI) and video electroencephalogram (VEEG) were normal. The efficacy of perampanel (PMP) in treating seizures and intellectual disability was apparent. Furthermore, 43 cases of ROGDI-related KTS were retrieved. 100% exhibited epilepsy, global developmental delay, and amelogenesis imperfecta. 17.2% received a diagnosis of attention deficit hyperactivity disorder (ADHD), and 3.4% were under suspicion of autism spectrum disorder (ASD). Language disorders were observed in all patients. Emotional disorders, notably self-harm behaviors (9.1%), were also reported. CONCLUSION ROGDI-related KTS is a rare neurodegenerative disorder, characterized by three classic clinical manifestations: epilepsy, global developmental delay, and amelogenesis imperfecta. Moreover, patients could present comorbidities, including ADHD, ASD, emotional disorders, and language disorders. PMP may be a potential drug with relatively good efficacy, but long-term clinical trials are still needed.

Abstract
OBJECTIVES To determine the proportion of children with severe acute malnutrition (SAM) having vitamin B12 deficiency, its clinical predictors, and its association with development. METHODS In this cross-sectional study, 100 children between 1 mo to 59 mo [mean (SD) age 17 (12.75) mo; 55 males], with diagnosis of SAM as per WHO criteria, were included. Serum vitamin B12, serum folate, and serum ferritin levels were measured by chemiluminescence immunometric assay method, while serum Homocysteine (Hcy) level was measured by enzymatic cycling method. Development assessment was done by Denver Development Screening Tool (DDST-II). RESULTS The mean (SD) serum vitamin B12 (cobalamin) levels were 296.52 (246.95) pg/mL; 45% children were vitamin B12 deficient (<203 pg/mL). Hyperhomocysteinemia (>14 µmol/L) was present in 39 (39%), and among these 69% (27/39) children had concomitant low serum vitamin B12 levels. Severe anemia and hypoproteinemia were significantly and independently associated with vitamin B12 deficiency [aOR (95% CI) 3.22 (1.13, 10) and 10 (1.66, 58.82), respectively]. Out of 45 children who were vitamin B12 deficient, 93%, 87%, 62% and 80% had gross motor, fine-motor, language and adaptive-cognitive delay, respectively. Vitamin B12 level was significantly associated (P <0.001) with developmental delay. CONCLUSIONS There is a high prevalence of vitamin B12 deficiency in children with SAM, which is also associated with development delay across all domains (except language) in these children.

Abstract
BACKGROUND Autism spectrum disorder is characterized by deficits in social communication and restricted or repetitive behaviors. Due to the extremely high genetic and phenotypic heterogeneity, it is critical to pinpoint the genetic factors for understanding the pathology of these disorders. METHODS We analyzed the exomes generated by the SPARK (Simons Powering Autism Research) project and performed a meta-analysis with previous data. We then generated 1 zebrafish knockout model and 3 mouse knockout models to examine the function of GIGYF1 in neurodevelopment and behavior. Finally, we performed whole tissue and single-nucleus transcriptome analysis to explore the molecular and cellular function of GIGYF1. RESULTS GIGYF1 variants are significantly associated with various neurodevelopmental disorder phenotypes, including autism, global developmental delay, intellectual disability, and sleep disturbance. Loss of GIGYF1 causes similar behavioral effects in zebrafish and mice, including elevated levels of anxiety and reduced social engagement, which is reminiscent of the behavioral deficits in human patients carrying GIGYF1 variants. Moreover, excitatory neuron-specific Gigyf1 knockout mice recapitulate the increased repetitive behaviors and impaired social memory, suggesting a crucial role of Gigyf1 in excitatory neurons, which correlates with the observations in single-nucleus RNA sequencing. We also identified a series of downstream target genes of GIGYF1 that affect many aspects of the nervous system, especially synaptic transmission. CONCLUSIONS De novo variants of GIGYF1 are associated with neurodevelopmental disorders, including autism spectrum disorder. GIGYF1 is involved in neurodevelopment and animal behavior, potentially through regulating hippocampal CA2 neuronal numbers and disturbing synaptic transmission.

Abstract
BACKGROUND Reasons for undernutrition are food insufficiency, impaired child care, limited access to healthcare, and maternal lack of health literacy. In addition, there are several environmental factors, such as drinking water quality, poor sanitation, and hygienic practices that can lead to poor nutritional status in children. The present study aimed to compare household-associated risk factors, including water, sanitation, and hygiene (WASH) practices of mothers, with children's stunting under the age of five. METHODS A face-to-face cross-sectional survey was conducted with mothers of children under the age of five in the Dera Ghazi Khan district in southern Punjab, Pakistan. World Health Organization criteria for stunting were used to identify the participants. A sociodemographic questionnaire was used to collect information from consented parents/guardians on children's age, feeding, and WASH practices. Pearson's chi-square, simple regression, and hierarchical regression models were applied for data analysis. RESULTS A total of 204 mothers of children of both genders participated in this study. The children's mean (SD) age was 15.67 (± 10.2) months, their weight was 5.44 (± 1.45) kg, their height was 67.69 (± 10.05), and their mid-upper arm circumference was 9.75 (± 1.30) cm. Children's stunting was mild (z-score > -2) at 17.6%, moderate (z-score - 2 to -3) at 16.7%, and severe (z-score < -3) at 65.7% of participants. A simple regression model showed a strong association, r2 = 0.062, p = 0.013, with age as the most significant sociodemographic factor. The hierarchical regression model showed a combined value of r2 = 0.0128, p = 0.027, with hand pump and tank water as the significant source of drinking water that was related to stunting among children. CONCLUSION Stunting can be associated with several risk factors, including WASH parameters. This study concluded that children aged under five years are susceptible to stunting in southern Punjab, Pakistan. The contamination of hand pumps and tank water resources was found to be the major contributing factor to stunting.

Abstract
Neurodevelopmental disorder with spastic diplegia and visual defects (NEDSDV) is a rare autosomal dominant genetic disorder caused by genetic alterations in the CTNNB1 gene. CTNNB1 is a gene that encodes β-catenin, an effector protein in the canonical Wnt pathway involved in stem cell differentiation and proliferation, synaptogenesis, and a wide range of essential cellular mechanisms. Mutations in this gene are also found in specific malignancies as well as exudative vitreoretinopathy. To date, only a limited number of cases of this disease have been reported, and though they share some phenotypic manifestations such as intellectual disability, developmental delay, microcephaly, behavioral abnormalities, and dystonia, the variety of phenotypic traits of these patients shows extreme heterogeneity. In this study, two cases of NEDSDV with de novo CTNNB1 mutations: c.1420C>T(p.R474X) and c.1377_1378Del(p.Ala460Serfs*29), found with whole exome sequencing (WES) have been reported and the clinical and paraclinical characteristics of these patients have been described. Due to such a wide range of clinical characteristics, the identification of new patients and novel variants is of great importance in order to establish a more complete phenotypic spectrum, as well as to conclude the genotype-phenotype correlations in these cases.

Abstract
BACKGROUND Allan-Herndon-Dudley syndrome (MCT 8 deficiency) is an X-linked recessive condition caused by hemizygous pathogenic variants in SLC16A2 encoding the monocarboxylate transporter 8 (MCT8). Patients present with global developmental delay and neurological impairment, and abnormal serum thyroid function tests. The drug, 3,3',5 triiodothyroacetic acid (TRIAC), was recently demonstrated to improve the endocrinological profile. Improvement in diagnostic approach is key to earlier start of treatment. PATIENT FINDINGS We described four Chinese patients with MCT8 deficiency undergoing different diagnostic odysseys. Their initial presentation included global developmental delay and dystonia. Patient 2 also had epilepsy. Patients 1 and 2 presented with two novel variants: (1)hemizygous NM_006517.4(SLC16A2):c.1170 + 2 T > A; p.(?), and (2)hemizygous NM_006517.4(SLC16A2):c.305dupT; p.(Val103GlyfsTer17) respectively. Patients 3 and 4 were biological brothers harboring hemizygous NM_006517.4(SLC16A2):c.305dupT; p.(Val103GlyfsTer17), which was first reported in 2004. We obtained the measurement of triiodothyronine (T3) and reverse T3 (rT3) from dried blood spot samples collected on Day 1 of life from Patient 1 and studied the biomarkers (rT3 and T3/rT3 ratio) proposed by Iwayama et al. for the detection of MCT8 deficiency at birth. Our data verified the significantly reduced rT3 level in Patient 1, compared with healthy newborns, although low T3 level and comparable T3/rT3 ratio with controls were detected. SUMMARY Patients with MCT8 deficiency often undergo diagnostic odysseys. An early diagnosis could be missed by a normal newborn thyroid function screening result based on biochemical measurement of TSH and/or T4/fT4. Early detection of rT3 is key to improving current diagnostic approach. CONCLUSION We recommend that full thyroid function profile (TSH, T4/fT4, T3/fT3, rT3) be considered early for all pediatric patients presenting with unexplained developmental delay and/or dystonia. The potential inclusion of rT3 measurement in newborn screening may prove promising.

Abstract
Coffin-Siris syndrome (CSS) is a rare congenital disorder characterized by coarse facial features, intellectual disability or developmental delay, and aplasia or hypoplasia of the tips of the fifth finger and/or toes. Mutations in genes affecting the switch/sucrose non-fermenting ATP-dependent chromatin remodeling complex are reported to cause CSS. Here, we describe three CSS patients. Two girls aged 3 and 2 years old presented with global developmental delay, poor growth, and a dysmorphic face. Whole-exome sequencing (WES) was performed and they were diagnosed with CSS due to heterozygous frameshift variants (c.3443_3444del, p.Lys1148ArgfsTer9 and c.2869_2890del, p.Pro957CysfsTer20) in ARID1B A 2-year-old girl presented with gross motor delay and dysmorphic face. She was diagnosed with CSS due to a novel heterozygous frameshift variant (c.4942_4943del: p.Gln1648GlyfsTer8) in ARID2.

Abstract
BACKGROUND Systematic or targeted screening for developmental delay (DD) is critical to the early identification of developmental disabilities. With limited available information for urban Rwandan children, this study aimed to determine the prevalence of DD and associated risk factors in infants aged 9 to 16 months living in the urban Rwandan city of Kigali. METHODS A cross-sectional study was conducted in Rwanda from August to November 2019. A convenience sample of 376 Rwandan parents/caregivers and their children attending urban health centers for their routine immunization visits at 9 and 15 months of age was studied. Parents/caregivers completed the official Kinyarwandan version of the Ages and Stages Questionnaire (ASQ-3) and established cutoffs were used to identify DD. Frequency and percentages were used to summarise the data. Logistic regression analysis was used to identify factors associated with DD. RESULTS Of the 358 children screened using the ASQ-3, the overall prevalence of DD was 24.6%, with a 27.2% prevalence among 9-10-month old children and 22.4% prevalence among 15-16-month old children. Delays in the combined group among the domains of gross motor, communication, fine motor, personal social, and problem solving were 12.8%, 2.5%, 8.4%, 1.7% and 7.5%, respectively. Gestational age at delivery and district of origin were most highly associated with DD, with preterm children at significantly higher risk of having DD compared to term children (Adjusted Odd Ratio AOR = 8.3; 95% CI = 2.5-27.4) and children from Nyarugenge District at high risk of DD compared to children from Gasabo district (AOR = 2.15; 95% CI = 1.2-3.9). CONCLUSIONS The prevalence of ASQ-detectable DD among urban Rwandan children between 9 and 16 months of age was 24.6%, with a high correlation to a history of prematurity and district of origin. This study demonstrates the need for thoughtful health planning regarding integrated developmental surveillance for children, particularly those at high risk, to allow for earlier identification and intervention in the urban area of Kigali, Rwanda.

Abstract
BACKGROUND Early childhood life is critical for optimal development and is the foundation of future well-being. Genetic, sociocultural, and environmental factors are important determinants of child development. AIM The objectives were to screen for suspected developmental delays (DDs) among Egyptian preschool children, and to explore the determinants of these delays based on sociodemographic, epidemiological, maternal, and child perinatal risk factors. METHODS A national Egyptian cross-sectional developmental screening of a representative sample of preschool children (21,316 children) aged 12 to 71 months. The Revised Denver Prescreening Developmental Questionnaire (R-PDQ) followed by the Denver Developmental Screening Test, 2nd edition (DDST) was used. RESULTS Each screened child manifested at least one of six developmental categories. Either typical development, gross motor delay (GM), fine motor adaptive delay (FMA), Language delay (L), Personal-social delay (PS), or multiple DDs. The prevalence of preschool children with at least one DD was 6.4%, while 4.5% had multiple DDs. Developmental language delay was the most prevalent, affecting 4.2% of children. The least affected domain was GM (1.9% of children). Boys were more likely to have DD than girls. Children in urban communities were more likely to have at least one DD than those in rural areas (OR = 1.28, 95%CI: 1.14-1.42), and children of middle social class than of low or high social class (OR = 1.49, 95%CI: 1.30-1.70 & OR = 1.40, 95%CI: 1.23-1.59 respectively). The strong perinatal predictors for at least one DD were children with a history of postnatal convulsions (OR = 2.68, 95%CI: 1.97-3.64), low birth weight (OR = 2.06, 95%CI: 1.69-2.52), or history of postnatal cyanosis (OR = 1.77, 95%CI: 1.26-2.49) and mothers had any health problem during pregnancy (OR = 1.73, 95%CI: 1.44-2.07). Higher paternal and maternal education decreased the odds of having any DD by 43% (OR = 0.57, 95% CI: 0.47-0.68) and 31% (OR = 0.69, 95%CI: 0.58-0.82) respectively. CONCLUSION This study demonstrates a considerable attempt to assess the types and the prevalence of DD among preschool children in Egypt. Perinatal factors are among the most common determinants of DD in preschool children and the majority could be preventable risk factors.

Abstract
OBJECTIVES To determine the diagnostic yield of next generation sequencing (NGS) in patients with moderate/severe/profound intellectual disability (ID) unexplained by conventional tests and to assess the impact of definitive diagnosis on the clinical management and genetic counselling of these families. METHODS This was a ambi-directional study conducted at Institute of Medical Genetics and Genomics, Sir Ganga Ram Hospital, New Delhi. The study comprised 227 patients (prospective cohort - 126, retrospective cohort - 101) in whom NGS based tests were performed. RESULTS The mean age of study cohort was 4.5 ± 4.4 y (2.5 mo to 37.3 y). The male: female ratio was 1.6:1. The overall diagnostic yield of NGS was 53.3% (121/227) with causative variants identified in 84 known ID genes. Autosomal recessive intellectual disability (ARID) (23.3%, 53/227) was the most common followed by autosomal dominant intellectual disability (ADID) (20.7%, 47/227) and X-linked intellectual disability (XLID) (9.2%, 21/227). The diagnostic yield was notably higher for ID plus associated condition group (55.6% vs. 20%) (p = 0.0075, Fisher's exact test) compared to isolated ID group. The impact of diagnosis on active or long-term management was observed in 17/121 (14%) and on reproductive outcomes in 26/121 (21.4%) families. CONCLUSIONS There is paucity of data on molecular genetic spectrum of ID from India. The current study identifies extensive genetic heterogeneity and the impact of NGS in patients with ID unexplained by standard genetic tests. The study identified ARID as the most common cause of ID with additional implications for reproductive outcomes. It reiterates the importance of phenotype in genetic testing.

Abstract
The present study aimed to evaluate the ability of the Bayley III screening tool to detect developmental delay in moderate to high-risk preterm children in India. In this cross-sectional study, 94 preterm babies were enrolled. The Bayley III screener (index test) and the gold-standard, Developmental assessment scale for Indian Infants (DASII) test were administered to all the enrolled children. Researchers were blinded while performing the tests. Diagnostic accuracy parameters were compared. The Bayley III screener's sensitivity and specificity for predicting the delay (with a DASII cut-off of <70) were 84.62% and 85.18% in the mental domain and 61.11% and 96.05% in the motor domain, respectively. When the DASII cut-off was raised to 85, the sensitivity and specificity in the mental domain were 60.61% and 95.08%, respectively, whereas they were 36.11% and 98.27%, respectively, in the motor domain. The Bayley III screener is found to have good specificity rather than sensitivity with good predictive values.

Abstract
Purpose To describe the presence of ocular abnormalities in children with developmental delay (DD) and compare with normal children; to analyze associated risk factors, systemic problems, and the possible treatment that can be delivered. Methods This was a cross sectional, observational study. We included children between one and 18 years, diagnosed as developmental delay in DD group, and next immediate age- and sex-matched children without developmental delay on the same day or during the same period in the control group. Detailed history and neuroimaging findings were noted. Uncorrected visual acuity, best-corrected visual acuity for distance and near, cycloplegic refraction, anterior, and posterior segment examination was carried out. Various ocular problems, delayed visual maturation (DVM), and cortical visual impairment (CVI) were diagnosed based on examination. Data were analyzed statistically, and P value <0.05 was considered as statistically significant. Results Ninety-four children were included in each group. Mean age was 4.97 ± 3.84 years, and 64.89% were males. In DD group: Most common abnormal neuroimaging finding was gliotic changes; systemic associations: 39 children; 83 children had ocular problems: refractive error-70, strabismus-39, cataract-five, amblyopia-16; DVM-13; CVI-13 children; glasses and vision stimulation were advised in 39 and 65 children, respectively; whereas, in control group: refractive error-36, strabismus-15, cataract-two; amblyopia-20 children. Conclusion 88.29% of developmental delay children had ocular abnormalities, commonest was refractive error (74.47%); these values were higher than in control group; common risk factors were low birthweight and consanguineous marriage; epilepsy was the most common systemic association.

Abstract
Objectives Congenital heart diseases (CHDs) are one of the most important congenital anomalies in children which have high-risk for neurodevelopment delay. This study was conducted to determine the proportion of developmental delay in children with CHD and comparison of delay between acyanotic and cyanotic heart diseases in children. Materials and Methods A cross-sectional study was conducted on children admitted in pediatric ward of rural hospital from 6 month to 6 years of age who are diagnosed with CHD by 2D ECHO and further classified into acyanotic congenital heart disease (ACHD) and cyanotic congenital heart disease (CCHD). Neurodevelopmental assessment was done using Trivandrum development screening chart (TDSC). Results Out of total 50 children in study population, 24 children had TDSC delay, distribution as 11 (22%) ACHD and 13 (26%) CCHD. Out of 24 children in the age group of 0-3 years, 13 (54.2%) were ACHD and 11 (45.8%) were CCHD. Out of 26 children in the age group of 3-6 years, 15 (57.7%) were ACHD and 11 (42.3%) were CCHD. Among different ACHD included in the study population (0-3 years) children with ventricular septal defect (VSD) were maximum (n = 5) next in the decreasing order was atrial septal defect (ASD) (n = 3). ACHD included in the study population (3-6 years) children with VSD was maximum (n = 6) next in the order was ASD (n = 4). Proportion of delay in children with ACHD was 22% as compared to 26% in children with CCHD. Conclusion There is a high proportion of neurodevelopmental delay in children with CHD which can be detected using TDSC which is a simple screening tool and can be used by any health-care professional without training for the assessment of neurodevelopmental outcome in these children. Delay was more in children with CCHD than ACHD.

Abstract
Pathogenic germline DICER1 variants are associated with pleuropulmonary blastoma, multinodular goiter, embryonal rhabdomyosarcoma and other tumour types, while mosaic missense DICER1 variants in the RNase IIIb domain are linked to cause GLOW (global developmental delay, lung cysts, overgrowth, and Wilms' tumor) syndrome. Here, we report four families with germline DICER1 pathogenic variants in which one member in each family had a more complex phenotype, including skeletal findings, facial dysmorphism and developmental abnormalities. The developmental features occur with a variable expressivity and incomplete penetrance as also described for the neoplastic and dysplastic lesions associated with DICER1 variants. Whole exome sequencing (WES) was performed on all four cases and revealed no further pathogenic or likely pathogenic dominant, homozygous or compound heterozygous variants in three of them. Notably, a frameshift variant in ARID1B was detected in one patient explaining part of her phenotype. This series of patients shows that pathogenic DICER1 variants may be associated with a broader phenotypic spectrum than initially assumed, including predisposition to different tumours, skeletal findings, dysmorphism and developmental abnormalities, but genetic work up in syndromic patients should be comprehensive in order not to miss additional underlying /modifying causes.

Abstract
CAMK2B encodes the beta-subunit of calcium/calmodulin-dependent protein kinase II (CAMKII), which is expressed mainly in the brain. Variants of CAMK2A and CAMK2B cause neurodevelopmental disorders, and CAMK2B alterations have been described in at least 14 patients with intellectual disability and developmental delay. Here, we describe a novel CAMK2B variant in a patient with tetralogy of Fallot (TOF), developmental delay, and growth retardation. The patient was a 2-year-old female. She was delivered at 36 weeks 6 days gestational age by caesarean section due to non-reassuring fetal status, with birth weight of 1680 g (-2.0 SD), birth length of 43.5 cm (-1.5 SD), and occipital-frontal head circumference (OFC) of 29.4 cm (-1.7 SD). Growth retardation, microcephaly, developmental delay, tetralogy of Fallot, and dysmorphic features were present. The patient controlled her head position at four months, rolled at six months, sat at 13 months, crawled at 18 months, and walked with support at 21 months. She began speaking words at 2 years old. Her dysmorphic features included a wide face, broad forehead, puffy eyelids, broad nasal base, broad and prominent philtrum, pointed chin, full cheeks, and prominent ears. A de novo missense CAMK2B variant (NM_172079.2:c.895A > G (p.Lys299Glu) NC_000007.14:g.44241708T > C (hg38)) was identified by proband exome sequencing and confirmed by Sanger sequencing. The variant was located at an autoregulatory segment and highly conserved among species. This patient displayed many of the physical features of CAMK2B-related neurodevelopmental disorder (NDD), but the TOF present in the current case is not a feature of patients with the NDD. Since a de novo CAMK2B (p.Leu443Val) variant has previously been found in a cohort of TOF, we conclude that CAMK2B variants may be associated with this specific cardiac defect.

Abstract
PURPOSE The "NALCN channelosome" is an ion channel complex that consists of multiple proteins, including NALCN, UNC79, UNC80, and FAM155A. Only a small number of individuals with a neurodevelopmental syndrome have been reported with disease causing variants in NALCN and UNC80. However, no pathogenic UNC79 variants have been reported, and in vivo function of UNC79 in humans is largely unknown. METHODS We used international gene-matching efforts to identify patients harboring ultrarare heterozygous loss-of-function UNC79 variants and no other putative responsible genes. We used genetic manipulations in Drosophila and mice to test potential causal relationships between UNC79 variants and the pathology. RESULTS We found 6 unrelated and affected patients with UNC79 variants. Five patients presented with overlapping neurodevelopmental features, including mild to moderate intellectual disability and a mild developmental delay, whereas a single patient reportedly had normal cognitive and motor development but was diagnosed with epilepsy and autistic features. All displayed behavioral issues and 4 patients had epilepsy. Drosophila with UNC79 knocked down displayed induced seizure-like phenotype. Mice with a heterozygous loss-of-function variant have a developmental delay in body weight compared with wild type. In addition, they have impaired ability in learning and memory. CONCLUSION Our results demonstrate that heterozygous loss-of-function UNC79 variants are associated with neurologic pathologies.

Abstract
Background Vitamin D deficiency is common in pregnant women. Some studies have linked vitamin D deficiency to obstetric complications such as gestational hypertension, gestational diabetes, and preterm birth. Therefore, the objective of this study is to investigate the potential impact of vitamin D deficiency during pregnancy on both perinatal and long-term outcomes. Methods In this retrospective study, conducted between 2017 and 2021, we analyzed the data of 1079 singleton pregnant women with no medical or surgical complications prior to pregnancy. We evaluated obstetric and perinatal outcomes, as well as neurodevelopmental outcomes using Bayley-III tests, Gross Motor Function Measure, or chart review. Results The maternal serum vitamin D level in the first trimester was 18.2 ± 9.0 ng/mL. Vitamin D deficiency (<20 ng/mL) was found in 308 (62.0%) women in the first trimester, of which 288 women (26.7%) were in the very deficient group (<10 ng/mL). There were no differences in maternal age, body mass index, and previous preterm birth between the group with vitamin D < 10 ng/mL and ≥10 ng/mL group. There were also no differences in the rates of gestational hypertension, gestational diabetes, and preterm birth between the two groups, except for the rate of preterm birth before 37 weeks of gestation, which was significantly higher in the very deficient group (adjusted odds ratios [aOR] = 7.78, 95%CI [2.23-27.12], p = 0.001). In the very deficient group, the risk of developmental delay was also higher (aOR = 4.28, 95%CI [1.40-13.05], p = 0.011). Conclusions This is the first study to analyze the effects of maternal vitamin D deficiency during pregnancy on both long-term developmental outcomes and perinatal prognosis. Vitamin D deficiency, defined as a level lower than 10 ng/mL in the first trimester, may increase the risk of preterm birth and developmental delay in children.
