Abstract
Cri-du-chat syndrome is a rare genetic disorder, due to a deletion of the short arm of chromosome 5 (5p-). Its incidence is ranging from 1/15000 to 1/50000 live births. This was a one-day-old male newborn from a non-consanguineous marriage, the first pregnancy uncomplicated and carried to term with a birth weight of 2295g. Clinical examination revealed: craniofacial dysmorphism with hypertelorism and microcephaly, hypotonia, poor suction and clubfoot more marked on the right, the rest of the examination was unremarkable. During hospitalization, a high-pitched monochromatic cry mimicking a cat's meow was observed. The clinical diagnosis was confirmed by fluorescence in situ hybridization, showing a deletion of the short arm of chromosome 5 (5p15.2). The basic malformative work-up came back without any other abnormalities. The association of a high-pitched monochromatic cry with craniofacial dysmorphism in a newborn should indicate the need for cytogenetic study, in particular fluorescence in siti hybridization.

Abstract
Otofaciocervical syndrome (OTFCS) is a rare genetic disorder of both autosomal recessive and autosomal dominant patterns of inheritance. It is caused by biallelic or monoallelic mutations in PAX1 or EYA1 genes, respectively. Here, we report an OTFCS2 female patient of 1st consanguineous healthy parents. She manifested facial dysmorphism, hearing loss, intellectual disability (ID), and delayed language development (DLD) as the main clinical phenotype. The novel homozygous variant c.1212dup (p.Gly405Argfs*51) in the PAX1 gene was identified by whole exome sequencing (WES), and family segregation confirmed the heterozygous status of the mutation in the parents using the Sanger sequencing. The study recorded a novel PAX1 variant representing the sixth report of OTFCS2 worldwide and the first Egyptian study expanding the geographic area where the disorder was confined.

Abstract
Neurodevelopment disorders can result in facial dysmorphisms. Therefore, the analysis of facial images using image processing and machine learning techniques can help construct systems for diagnosing genetic syndromes and neurodevelopmental disorders. The systems offer faster and cost-effective alternatives for genotyping tests, particularly when dealing with large-scale applications. However, there are still challenges to overcome to ensure the accuracy and reliability of computer-aided diagnosis systems. This article presents a systematic review of such initiatives, including 55 articles. The main aspects used to develop these diagnostic systems were discussed, namely datasets - availability, type of image, size, ethnicities and syndromes - types of facial features, techniques used for normalization, dimensionality reduction and classification, deep learning, as well as a discussion related to the main gaps, challenges and opportunities.

Abstract
The 3D prediction of post-operative changes is an inevitable tool for the surgical correction of facial asymmetry. The objective is to execute an evidence-based review answering the following question. Does the 3D virtual prediction planning draw reliable and accurate results in the surgical outcome related to the soft tissues of the face in facial asymmetry? This systematic review of the literature is based on the 3D soft tissue prediction planning of facial asymmetry correction to draw conclusions on the reliability and accuracy of these methods in the surgical outcome related to the soft tissues of the face. PubMed, Web of Science, Cochrane, and Ovid databases were adopted for the literature search. Studies published between years 2000 and 2020, aimed at the assessment of soft tissue predictions using software prediction packages for facial asymmetry, were selected. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) was applied. Quadas-2 tool was used for the qualitative evaluation of selected studies. Initial search yielded 248 articles. Twenty articles fulfilled the inclusion and exclusion criteria and selected for qualitative analysis. Finally, 12 articles were selected for quantitative analysis. The results indicate 3D imaging prediction methods provided more accurate information with less distortion for soft tissue prediction regardless of various softwares currently available. The prediction of soft tissue accuracy in facial asymmetry was less accurate in lower face regardless of the type of surgery for facial asymmetry. The mean prediction error was less than 2 mm.

Abstract
Introduction Partial trisomy 6p is a rare chromosomal anomaly, characterized by low birth weight, developmental delay, craniofacial abnormalities, feeding difficulties, congenital heart defects, and renal abnormalities. Some of the partial trisomy 6p cases reported in the literature included partial monosomy of another chromosome. This is often due to the fact that one of the parents is a balanced translocation carrier, thereby making it difficult to determine the genotype-phenotype relationship. Pure partial trisomy 6p cases are even rarer and may occur as a result of a marker chromosome, tandem or inverted duplication, and interchromosomal insertion. Case Presentation In this study, we evaluated the physical characteristics and genetic data of a 2-year-old girl with developmental delay and facial dysmorphic features. Dysmorphology assessment revealed the presence of a prominent forehead, short and narrow palpebral fissures, blepharoptosis, convex nasal ridge, hemangioma on the left eyelid, high-arched palate, retromicrognathia, and low-set ears. The patient‧s G-banded karyotype was 46,XX,der(2)t(2;6)(q37.3;p22.1). Upon SNP-array analysis, aimed to determine the origin of the extra chromosomal material detected in chromosome 2 of the patient, there was a de novo 27.5-Mb duplication at 6p, arr[GRCh37] 6p25.3p22.1(204,909_27,835,272)×3, interpreted to be pathogenic. Conclusion We present this case report to clarify the clinical findings of a rare chromosomal anomaly, discuss the genes that may be related to the phenotype and contribute to the literature in terms of knowledge regarding genotype-phenotype correlation.

Abstract
PURPOSE We previously defined biallelic HYAL2 variants causing a novel disorder in 2 families, involving orofacial clefting, facial dysmorphism, congenital heart disease, and ocular abnormalities, with Hyal2 knockout mice displaying similar phenotypes. In this study, we better define the phenotype and pathologic disease mechanism. METHODS Clinical and genomic investigations were undertaken alongside molecular studies, including immunoblotting and immunofluorescence analyses of variant/wild-type human HYAL2 expressed in mouse fibroblasts, and in silico modeling of putative pathogenic variants. RESULTS Ten newly identified individuals with this condition were investigated, and they were associated with 9 novel pathogenic variants. Clinical studies defined genotype-phenotype correlations and confirmed a recognizable craniofacial phenotype in addition to myopia, cleft lip/palate, and congenital cardiac anomalies as the most consistent manifestations of the condition. In silico modeling of missense variants identified likely deleterious effects on protein folding. Consistent with this, functional studies indicated that these variants cause protein instability and a concomitant cell surface absence of HYAL2 protein. CONCLUSION These studies confirm an association between HYAL2 alterations and syndromic cleft lip/palate, provide experimental evidence for the pathogenicity of missense alleles, enable further insights into the pathomolecular basis of the disease, and delineate the core and variable clinical outcomes of the condition.

Abstract
Rare deletions and duplications on the long arm of Chromosome 21 have previously been reported in many patients with craniofacial and developmental phenotypes. However, this Down Syndrome Critical Region (DSCR) contains multiple genes, making identifying a single causative gene difficult. Here, we report a case of a boy with bicoronal craniosynostosis, facial dysmorphism, developmental delay, and intellectual impairment who was found by whole genome sequencing to have a homozygous missense mutation in the Single-Minded Homolog 2 (SIM2) gene (c.461 A > G, p.Tyr154Cys) within the DSCR. SIM2 encodes an essential bHLH and PAS domain transcription factor expressed during fetal brain development and acts as a master regulator of neurogenesis. This variant is globally very rare, segregates in the family, and is predicted to be highly deleterious by in silico analysis, 3D molecular modeling of protein structure, and functional analysis of zebrafish models. Zebrafish expressing the human SIM2p.Y154C variant displayed a progressed microcephaly-like phenotype and head shape abnormalities. When combined with careful phenotyping of the patient vis-à-vis previously reported cases harboring structural variants in this critical 21q22 region, the data support a pathogenic role of SIM2 in this complex syndrome and demonstrates the utility of next-generation sequencing in prioritizing genes in contiguous deletions/duplications syndromes and diagnosing microarray-negative patients in the craniofacial clinic.

Abstract
Background Arboleda-Tham syndrome (ARTHS), caused by a pathogenic variant of KAT6A, is an autosomal dominant inherited genetic disorder characterized by various degrees of developmental delay, dysmorphic facial appearance, cardiac anomalies, and gastrointestinal problems.
Case presentation A baby presented multiple facial deformities including a high arched and cleft palate, with philtral ridge and vermilion indentation, a prominent nasal bridge, a thin upper lip, low-set ears, an epicanthal fold, and cardiac malformations. Whole exome sequencing (WES) revealed a heterozygous nonsense mutation in exon 8 of the KAT6A gene (c.1312C>T, p.[Arg438*]) at 2 months of age. After a diagnosis of ARTHS, an expressive language delay was observed during serial assessments of developmental milestones. Conclusions In this study, we describe a case with a novel KAT6A variant first identified in Korea. This case broadens the scope of clinical features of ARTHS and emphasizes that WES is necessary for early diagnosis in patients with dysmorphic facial appearances, developmental delay, and other congenital abnormalities.

Abstract
OBJECTIVE Joubert syndrome (JS) is a rare syndrome characterized by ataxia and the molar tooth sign (MTS) on imaging. The present study aims to explore the clinical and radiological features in a cohort of patients with JS. METHODS This was a retrospective chart review of patients with JS evaluated by movement disorder specialists. RESULTS Nine patients were included in the study. All patients had facial dysmorphism and ocular abnormalities, and 4 patients had dystonia. Ocular tilt reaction and alternate skew deviation (66%) were the most common ocular abnormalities. Horizontally aligned superior cerebellar peduncles were observed in all four patients with diffusion tensor imaging, with a lack of decussation in three. Exome sequencing performed in four patients revealed novel variants in the MKS1, CPLANE1, and PIBF1 genes. CONCLUSION Facial dysmorphism, ocular abnormalities and classical imaging findings were observed in all patients with JS. Apart from ataxia, dystonia and myoclonus are other movement disorders observed in JS.

Abstract
Myhre syndrome (MS) is a rare autosomal-dominant disorder characterized by short stature, intellectual disability, skeletal anomalies, restricted joint mobility, distinctive facial dysmorphism, and deafness. Early diagnosis of MS is difficult because its features progress and become noticeable at school age. Recently, the SMAD4 gene was identified as the major gene responsible for MS. Herein, we report the first Korean case of MS after identification of a SMAD4 mutation by clinical exome sequencing. The patient was born small for gestational age, and she had the typical clinical features of MS, including short stature, characteristic facial appearance, developmental delay, and selective mutism. She was diagnosed with central precocious puberty. Because of the patient's precocious puberty and short stature, we administered combined recombinant human growth hormone and gonadotropin-releasing hormone agonist treatments, which resulted in improved height. While there have been 79 cases of MS reported worldwide, to our knowledge, this is the first case of genetically-confirmed MS in Korea.

Abstract
TRIO is a Dbl family guanine nucleotide exchange factor (GEF) and an important regulator of neuronal development. Most truncating and missense variants affecting the Dbl homology domain of TRIO are associated with a neurodevelopmental disorder with microcephaly (MIM617061). Recently, de novo missense variants affecting the spectrin repeat region of TRIO were associated with a novel phenotype comprising severe developmental delay and macrocephaly (MIM618825). Here, we provide more evidence on this new TRIO-associated phenotype by reporting two severely affected probands with de novo missense variants in TRIO affecting the spectrin repeat region upstream of the typically affected GEF1 domain of the protein.

Abstract
Chromosomal microdeletion syndromes usually present with neurological abnormalities, developmental delays, and various systemic abnormalities. 1p31 microdeletion syndrome is one of the novel microdeletion syndromes that usually presents with developmental delay, intellectual disability, various craniofacial abnormalities, and other systemic abnormalities in a proportion of cases. NEGR1 and NFIA are few of the genes present in this locus responsible for these symptoms. However, none of the reported cases had only isolated intellectual disability. Here, we are reporting a case of 1p31 microdeletion syndrome with isolated moderate intellectual disability and hyperactivity in an 11-year-old boy. It is essential for clinicians to be aware of such an atypical presentation of 1p31.1 microdeletion syndrome, to maintain reasonable clinical suspicion in cases with unexplained intellectual disability.

Abstract
BACKGROUND Recent studies have suggested that two PACS2 pathogenic variants, c.625G > A (p.Glu209Lys) and c.631G > A (p.Glu211Lys), have been causally linked to the characteristic developmental and epileptic encephalopathy, including autistic behaviors, hypotonia, cerebellar dysgenesis and facial dysmorphism. Their seizures appear most difficult to control in neonatal and infant period, but improve after the first year of life. We herein report three patients with the same PACS2 variant, c.625G > A (p.Glu209Lys), showing different characteristics from previous reports. CASE REPORT Case 1, a 2-year-old girl, developed frequent tonic convulsions 2 weeks after birth. Brain magnetic resonance imaging showed a decrease in posterior periventricular white matter volume, an enlargement of the inferior horn of lateral ventricles and old subependymal hemorrhage. Epilepsy is now controlled with antiepileptic drugs. Case 2, a 12-year-old girl, developed generalized tonic convulsions 3 days after birth. Although epilepsy had been controlled since the age of 4, she developed Lennox-Gastaut syndrome at 9 years old. Case 3, a 3-year-old girl, developed tonic convulsions 3 days after birth. She now exhibits normal psychomotor development, and epilepsy is controlled without medicine. CONCLUSION PACS2-related epileptic syndrome presents variable phenotypes than previously reported. We think that our findings expand the clinical spectrum of this disease, and provide important information about the differential diagnosis of neonatal-onset epileptic syndrome.

Abstract
Peroxisomal disorders are a heterogeneous group of inborn errors of metabolism that result in impaired function of the peroxisome. Within this, single enzyme deficiencies are known to cause a constellation of symptoms not very different from the peroxisome biogenesis defects. Thus, there is a need to identify features that differentiate the two. We present 3 molecularly confirmed families: 1 with Acyl CoA oxidase deficiency and 2 with D-bifunctional protein deficiency. The clinical, biochemical, and radiological features of these patients have been discussed. We attempt to highlight the overlap in facial features as well as strikingly similar MRI findings of cerebellar atrophy and white matter hyperintensities. This unique clinical profile will not only help in reaching a quick diagnosis, but in this era of variants of uncertain significance, it will prove as supporting evidence. Finally, we expand the genotypic spectrum with a description of 3 homozygous novel mutations (HSD17B4: c.670C>T, c.1807T>C; ACOX1: 1.03-kb exonic deletion) and discuss the role of protein modeling its establishing pathogenicity.

Abstract
BACKGROUND Wolf-Hirschhorn syndrome is a well-characterized genomic disorder caused by 4p16.3 deletions. Wolf-Hirschhorn syndrome patients exhibit characteristic facial dysmorphism, growth retardation, developmental delay, intellectual disability and seizure disorders. Recently, NSD2 gene located within the 165 kb Wolf-Hirschhorn syndrome critical region was identified as the key causal gene responsible for most if not all phenotypes of Wolf-Hirschhorn syndrome. So far, eight NSD2 loss of function variants have been reported in patients from different parts of the world, all were de novo variants. METHODS In our study, we performed whole exome sequencing for two patients from one family. We also reviewed more NSD2 mutation cases in pervious literature. RESULTS A novel loss of function NSD2 variant, c.1577dupG (p.Asn527Lysfs*14), was identified in a Chinese family in the proband and her father both affected with intellectual disability. After reviewing more NSD2 mutation cases in pervious literature, we found none of them had facial features that can be recognized as Wolf-Hirschhorn syndrome. In addition, we have given our proband growth hormone and followed up with this family for 7.5 years. CONCLUSIONS Here we reported the first familial NSD2 variant and the long-term effect of growth hormone therapy for patients. Our results suggested NSD2 mutation might cause a distinct intellectual disability and short stature syndrome.

Abstract
Mowat-Wilson syndrome (MWS) is a rare autosomal dominant syndrome characterized by distinctive facial features, congenital heart defects, Hirschsprung disease, genitourinary anomalies, various structural brain anomalies, and intellectual disability. Pathogenic mutations that result in haploinsufficiency in the ZEB2 gene cause MWS. In this study, we aimed to evaluate the clinical features and molecular analysis results of 4 MWS patients. All patients were examined by an expert clinical geneticist. Dysmorphological abnormalities were recorded. Data including demographic, clinical, and laboratory findings were obtained from hospital records. ZEB2 gene analysis was performed using a Sanger sequencing method. All patients had typical facial features of MWS such as widely spaced eyes, broad eyebrows with a medial flare, low-hanging columella, prominent or pointed chin, open-mouth expression, and uplifted earlobes. Four different heterozygous mutations were identified; 2 mutations were frameshift (c.246_247delGGinsC, c.980_980delG), 1 was nonsense (c.2083C>T), and 1 was splice site (c.808-2A>G). Two of them (c.246_247delGGinsC, c.980_980delG) have not been previously reported in the literature. By defining 2 novel mutations, this study contributes to the molecular spectrum of MWS, while also providing a further insight for genetic counseling. It also demonstrates the importance of dysmorphological examination in clinical diagnosis.

Abstract
BACKGROUND Agenesis of the corpus callosum (ACC) is a relatively common brain malformation in children with developmental disabilities, caused by mutations in many genes. These genetic causes are characterized by their extreme heterogeneity with more than 300 causative genes identified to date. CASE REPORT We describe two new cases from a three-generation family with ACC and a de novo mutation of the sonic hedgehog (SHH) gene. The affected family members had mild intellectual disability, broad forehead, and widely spaced eyes. A next-generation sequencing (NGS) approach revealed a stop-gain mutation (NM_000193.2:c.1300_1301insA p.Trp434Ter) of the SHH gene; it is the first family to report ACC associated with a single SHH gene mutation. CONCLUSION ACC with mild intellectual disability and facial dysmorphism may be caused by a mutation in SHH, but further research investigating the genotype-phenotype correlation of SHH mutations is required.

Abstract
Background Persistent neonatal hypoglycemia, owing to the possibility of severe neurodevelopmental consequences, is a leading cause of neonatal care admission. Hyperinsulinemic hypoglycemia is often resistant to dextrose infusion and needs rapid diagnosis and treatment. Several congenital conditions, from single gene defects to genetic syndromes should be considered in the diagnostic approach. Kabuki syndrome type 1 (MIM# 147920) and Kabuki syndrome type 2 (MIM# 300867), can be associated with neonatal hyperinsulinemic hypoglycemia. Patient presentation We report a female Italian (Sicilian) child, born preterm at 35 weeks gestation, with persistent hypoglycemia. Peculiar facial dysmorphisms, neonatal hypotonia, and cerebellar vermis hypoplasia raised suspicion of Kabuki syndrome. Hyperinsulinemic hypoglycemia was confirmed with glucagon test and whole-exome sequencing (WES) found a novel heterozygous splicing-site mutation (c.674-1G > A) in KMT2D gene. Hyperinsulinemic hypoglycemia was successfully treated with diazoxide. At 3 months corrected age for prematurity, a mild global neurodevelopmental delay, postnatal weight and occipitofrontal circumference growth failure were reported. Conclusions Kabuki syndrome should be considered when facing neonatal persistent hypoglycemia. Diazoxide may help to improve hyperinsulinemic hypoglycemia. A multidisciplinary and individualized follow-up should be carried out for early diagnosis and treatment of severe pathological associated conditions.

Abstract
The NEXMIF (KIAA2022) gene is located in the X chromosome, and hemizygous mutations in NEXMIF cause X-linked intellectual disability in male patients. Female patients with heterozygous mutations in NEXMIF also show similar, but milder, intellectual disability. Most female patients demonstrate intractable epilepsy compared with male patients, and the treatment strategy for epilepsy is still uncertain. Thus far, 24 female patients with NEXMIF mutations have been reported. Of these 24 patients, 20 also have epilepsy. Until now, epilepsy has been controlled in only 2 of these female patients. We report a female patient with a heterozygous de novo mutation, NM_001008537.2:c.1123del (p.Glu375Argfs*21), in NEXMIF. The patient showed mild intellectual disability, facial dysmorphism, obesity, generalized tonic-clonic seizures, and nonconvulsive status epilepticus. Sodium valproate was effective but caused secondary amenorrhea. We successfully treated her epilepsy with clonazepam without side effects, indicating that clonazepam might be a good choice to treat epilepsy in patients with NEXMIF mutations.

Abstract
The product of the BCL11B (B-Cell Leukemia 11) gene is a bi-functional transcriptional regulator that can act as either a repressor or an activator. It plays an important role in the development of the nervous, immune, and cutaneous systems, and is also involved in dental and craniofacial development. BCL11B-Related Disorder (BCL11BRD) is a novel rare neurodevelopmental disorder associated with mutations in BCL11B. A total of 17 patients have been described in the literature thus far. The main symptoms of BCL11BRD include global developmental delay, speech impairment, dental anomalies, feeding difficulties, refractive errors, dysmorphic features, and immunological abnormalities. In this report, we describe two Canadian girls, with pathogenic de novo BCL11B variants, both diagnosed via exome sequencing. One of the patients had global developmental delay, dental anomalies, dysmorphic features, dyskinesia and hypotonia; the latter two symptoms have not been previously reported in patients with BCL11BRD. She also had dysgenesis of corpus callosum and dilatation of the frontal horns of lateral ventricles, a brain anomaly that has been previously reported in only one other patient. The second patient had developmental delay, dysmorphic features, spasticity in lower limbs and dental anomalies. Our report contributes to the knowledge of the BCL11BRD, expands the clinical phenotype, and can also aid with genetic counseling of newly identified patients.

Abstract
BACKGROUND Congenital ataxias associated with cerebellar atrophy are clinically heterogeneous conditions with a variable age of onset and a diverse molecular basis. The hypothesis-free approach of genomic sequencing has led to the discovery of new genes implicated in these disorders and the identification of unexpected genotype-phenotype correlations. Although a recurrent heterozygous mutation (p.Arg1715His) in CACNA1G is known to cause adult-onset spinocerebellar ataxia 42 (SCA42*616795), gain-of-function mutations in this gene have recently been identified by whole exome sequencing (WES) in four children with cerebellar atrophy and ataxia, psychomotor delay, and other variable features. METHODS We describe four children from unrelated families with cerebellar anomalies on magnetic resonance imaging (atrophy or hypoplasia of the cerebellar vermis), hypertonia, psychomotor and speech delay, severe intellectual disability, ophthalmologic features and peculiar dysmorphic traits. All patients underwent a trio-based WES analysis. Clinical records were used to characterize the clinical profile of this newly recognized disorder. RESULTS Two previously reported de novo disease-causing mutations in CACNA1G (c.2881G>A, p.Ala961Thr and c.4591A>G, p.Met1531Val) were identified in these patients, providing further evidence of the specific impact of these variants. All four patients exhibit distinctive dysmorphic and ectodermal features which overlap those of the previously reported patients, allowing us to define the major features characterizing this homogeneous neurodevelopmental syndromic disorder associated with upregulated CACNA1G function. CONCLUSION Our findings confirm the specific association between a narrow spectrum of missense mutations in CACNA1G and a novel syndrome with infantile-onset cerebellar ataxiaand provide a dysmorphologic delineation of this novel neurodevelopmental trait.

Abstract
PURPOSE To identify and determine variations on eye distance in patients with bilateral nasal polyposis (BNP) compared to a healthy control group. METHODS This is a case-control study that included 20 BNP patients and 40 healthy controls. We included all patients with BNP confirmed by pathology and a computed tomography scan. A healthy control group was admitted, filtered by the exclusion criteria of nasal polyposis, craniofacial malformations, and encephalocele. Paranasal sinus CT scans were performed in all participants, and two measures were evaluated, the interoptic (soft tissue) and the interzygomatic (bone structure) distances. RESULTS A total of 20 BNP subjects, 13 (65%) male and 7 (35%) female, with a mean age of 38.8 years, and 40 healthy controls, 16 (40%) male and 24 (60%) female with a mean age of 43.2 years, were included. The mean interoptic distance was 69.7 mm (71.9 mm men, 66.4 mm women) and interzygomatic distance was 103.1 mm (104.5 mm men, 100.6 mm women). A significant increase of the interoptic (p < 0.001) and interzygomatic (p < 0.002) measurements was found in patients with polyposis compared to the controls. In the receptor operative curve analysis, the interoptic distance had an area under a curve of 96% and the threshold that maximizes the sensitivity and specificity was 59.85 mm (sensitivity 90%, specificity 95%, PPV 90%, NPV 95%). CONCLUSIONS An increase in ocular and orbital distances was identified in patients with BNP. Polyposis may be identified by measuring eye separation. The established cut point distance identifies patients that may benefit from follow-up. Further research in this study line is suggested.

Abstract
BACKGROUND FOXP1 is known as the gene responsible for neurodevelopmental delay associated with language impairment. Broad clinical findings also include feeding difficulty, muscular hypotonia, and distinctive features. These findings are common between patients with loss-of-function mutations in FOXP1 and 3p13 microdeletion involving FOXP1. Thus, "FOXP1-related intellectual disability syndrome" is now recommended. METHODS After obtaining informed consent, chromosomal microarray testing was performed for patients with unknown etiology. RESULTS We identified three Japanese patients with 3p13 microdeletions involving FOXP1. One of the patients showed an additional 1q31.3q32.1 deletion as de novo, which was rather considered as a benign copy number variant. CONCLUSION This is the first report of patients with 3p13 microdeletions from Japan. All patients showed growth delay, moderate to severe developmental delay, hearing loss, and distinctive facial features including prominent forehead and mid facial hypoplasia. In addition, "square shaped face" commonly observed in all three patients may be a characteristic finding undescribed previously. From the obtained findings, "FOXP1-related intellectual disability syndrome" was considered to be clinically recognizable.

Abstract
BACKGROUND Germline mutations of the PTEN gene are responsible for several PTEN hamartoma tumor syndromes. They are also implicated as a cause of macrocephaly and mild to severe developmental delay, regardless of the presence or absence of hamartomas in childhood. Nevertheless, because of limited information, the clinical features present during childhood in patients with a PTEN mutation are yet to be elucidated. METHODS PTEN mutations were investigated by multiplex targeted sequencing of genomic DNA from 33 children with increased head circumference (>+2 SD) and developmental delay. The clinical features of all the patients with a PTEN mutation were abstracted by dysmorphologists. RESULTS We have identified six children with a PTEN mutation. Clinical dissection of these six patients, in addition to patient reports in the literature, revealed distinctive facial features that included frontal bossing, dolichocephaly, horizontal eyebrows, and a depressed nasal bridge. Macrocephaly (+3.2 to +6.0 SD) was noticeable compared to their height (-0.8 to +2.1 SD), and the difference in the SD value of head circumference and height was more than 3 SD in all patients. CONCLUSION The presence of distinctive facies, extreme macrocephaly with normal to mildly high stature, and developmental delay may be useful for identifying patients with a PTEN mutation in childhood. Early identification of patients with a PTEN mutation would help uncover the natural course of tumor development in this group of individuals who have a possible predisposition to cancer, and be important for the development of an optimal surveillance strategy.

Abstract
Proximal deletion of 6q is a relatively rare chromosomal abnormality. Reported patients have deletions of different sizes but share partial overlap and present with similar clinical features, and some of them were described prior to the introduction of chromosome microarrays. We describe a male patient with prenatal sonographic findings of nuchal edema, intrauterine growth restriction, renal pelvis dilatation, and oligohydramnios. At birth, facial dysmorphism, retro/micrognathia, a short and wide neck as well as cardiovascular and renal anomalies were noted. His clinical evolution has been marked by failure to thrive, severe developmental delay, and cognitive impairment. The diagnosis of Toriello-Carey syndrome (TCS) was based on his "gestalt." aCGH identified a de novo proximal deletion of 17 Mb in 6q (6q12q14.3). Deletion 6q13q14 seems to be responsible for the main facial features and should be considered within the differential diagnosis of TCS.

Abstract
We described a 5-year-old male with hypodontia, hypohidrosis, and facial dysmorphisms characterized by a depressed nasal bridge, maxillary hypoplasia, and protuberant lips. Chromosomal analysis revealed a normal 46,XY male karyotype. Due to the presence of clinical features of hypohidrotic ectodermal dysplasia (HED), the EDA gene, located at Xq12q13.1, of the patient and his family was sequenced. Analysis of the proband's sequence revealed a missense mutation (T to A transversion) in hemizygosity state at nucleotide position 158 in exon 1 of the EDA gene, which changes codon 53 from leucine to histidine, while heterozygosity at this position was detected in the slightly affected mother; moreover, this mutation was not found in the publically available Human Gene Mutation Database. To date, our findings indicate that a novel mutation in EDA is associated with X-linked HED, adding it to the repertoire of EDA mutations.

Abstract
X-linked intellectual disability accounts for 10-12% of cases of cognitive impairment in males. Mutations in IL1RAPL1 are an emerging form of apparently non-syndromic X-linked intellectual disability. We report a 8-year-old intellectually disabled boy with speech delay, and unusual facial and digital anomalies who showed a novel and complex IL1RAPL1 rearrangement. It was defined by two intragenic non-contiguous duplications inherited from the unaffected mother. Chromosome X inactivation study on the mother's blood leukocytes, urinary sediment and buccal swab did not show a significant skewed inactivation. Comparison with previously described patients with IL1RAPL1 disruption was carried. Although data on craniofacial features were scanty in many papers, subtle facial dysmorphism with a thin upper lip seemed a quietly represented picture without any other genotype-phenotype correlations. Our study expands the molecular repertoire of IL1RAPL1 mutations in intellectual disability and points out the need of more accurate clinical descriptions to better define the related phenotype.

Abstract
We report two unrelated patients with overlapping chromosome 2q13 deletions (patient 1 in chr2:111415137-113194067 bp and patient 2 in chr2:110980342-113007823 bp, hg 19). Patient 1 presents with developmental delay, microcephaly and mild dysmorphic facial features, and patient 2 with autism spectrum disorder, borderline cognitive abilities, deficits in attention and executive functions and mild dysmorphic facial features. The mother and maternal grandmother of patient 1 were healthy carriers of the deletion. Previously, 2q13 deletions were reported in 27 patients, and the interpretation of its clinical significance varied. Our findings support that the 2q13 deletion is associated with a developmental delay syndrome manifesting with variable expressivity and reduced penetrance which poses a challenge for genetic counselling as well as the clinical recognition of 2q13 deletion patients.

Abstract
We report on a family with a not earlier described multiple congenital malformation. Several male family members suffer from laryngeal obstruction caused by bilateral vocal cord paralysis, outer and middle ear deformity with conductive and sensorineural hearing loss, facial dysmorphisms, and underdeveloped shoulder musculature. The affected female members only have middle ear deformity and hearing loss. The pedigree is suggestive of an X-linked recessive inheritance pattern. SNP-array revealed a deletion and duplication on Xq28 in the affected family members. A possible aetiology is a neurocristopathy with most symptoms expressed in structures derived from branchial arches.

Abstract
We report a 12-year-old boy referred to the Clinical Genetics service in view of facial dysmorphism, learning difficulties and autistic spectrum disorder. 60K arrayCGH revealed an 8.2-Mb duplication on chromosome 13q31.3q32.3, which was paternally inherited. This specific duplication on chromosome 13 has not been previously reported in the medical literature, and there are no familial or de novo patients with the same duplication breakpoints. This region contains 24 OMIM genes, including the glypicans GPC5 and GPC6, and the ZIC2 gene. We discuss the relevance of this chromosome imbalance and discuss the impact of this duplication on our patient's phenotype. Given that the duplication on 13q was paternally inherited, and although initially thought to be of uncertain significance, on exploring the family history further, it became apparent that the father had learning difficulties as a child and previous surgery for congenital diaphragmatic hernia. Here we explore the phenotype in association with this novel duplication on chromosome 13q and add to the existing literature on array findings within this region.

Abstract
We reported a 64-year-old autopsy case, showing a unique combination of disorders in visceral organs and brain. She had developmental delay, microencephaly, and facial dysmorphism. She developed sick sinus syndrome and liver cirrhosis. There were no abnormalities in laboratory tests for congenital metabolic errors or anomaly syndromes, including activities of lysosomal enzymes, isoelectric focusing of serum transferrin or array comparative genomic hybridization. She died of cardiorespiratory failure. At autopsy she showed liver cirrhosis and mesangial proliferation. The brain weighed 710 g. Bizarre putaminal changes were found, in which the size of area of putamen in coronal sections was small, aberrant fiber running was increased, and immunoreactivity for tyrosine hydroxylase was reduced. Loss of Purkinje cells was found throughout the cerebellar cortex. She had unreported combination of developmental delay, facial dysmorphism, small brain, bizarre putaminal lesion, cerebellar atrophy, cardiac disease, liver cirrhosis and renal disease. Although the exact cause of disease still remains to be investigated, it will be a clue for the establishment of new disease entity to accumulate subjects having the similar phenotype.

Abstract
Cold-induced sweating syndrome (CISS) is a rare autosomal recessive disorder characterized by profuse sweating at cold environmental temperatures, facial dysmorphism and skeletal features. The infantile presentation of CISS, referred to as Crisponi syndrome (CS), is characterized by facial muscular contractures in response to slight tactile stimuli or during crying, by life-threatening feeding difficulties caused by suck and swallow inabilities, and by intermittent hyperthermia. High febrile crises can lead to death within the first months of life. In preadolescence, surviving patients develop kyphoscoliosis and abnormal sweating. CISS is a genetically heterogeneous disorder caused by mutations in CRLF1 in more than 90 percent of patients (CISS1) and by mutations in CLCF1 in the remaining patients (CISS2). It is now well demonstrated that all patients with an infantile-onset CS will develop CISS, confirming that CS and CISS are not "allelic disorders" but the same clinical entity described at different ages of affected patients. Here we report on a Turkish patient with a phenotype consistent with CS/CISS1 and a nonsense homozygous mutation (c.829C>T, p.R277X) in the CRLF1 gene. This mutation has already been reported in another Turkish patient with CS/CISS1.
