Impact of genetic and non-genetic factors on phenotypic diversity in NBAS-associated disease. Mol Genet Metab 2024; 141:108118.

Abstract
Biallelic pathogenic variants in neuroblastoma-amplified sequence (NBAS) cause a pleiotropic multisystem disorder. Three clinical subgroups have been defined correlating with the localisation of pathogenic variants in the NBAS gene: variants affecting the C-terminal region of NBAS result in SOPH syndrome (short stature, optic atrophy, Pelger-Huët anomaly), variants affecting the Sec 39 domain are associated with infantile liver failure syndrome type 2 (ILFS2) and variants affecting the ß-propeller domain give rise to a combined phenotype. However, there is still unexplained phenotypic diversity across the three subgroups, challenging the current concept of genotype-phenotype correlations in NBAS-associated disease. Therefore, besides examining the genetic influence, we aim to elucidate the potential impact of pre-symptomatic diagnosis, emergency management and other modifying variables on the clinical phenotype. We investigated genotype-phenotype correlations in individuals sharing the same genotypes (n = 30 individuals), and in those sharing the same missense variants with a loss-of-function variant in trans (n = 38 individuals). Effects of a pre-symptomatic diagnosis and emergency management on the severity of acute liver failure (ALF) episodes also were analysed, comparing liver function tests (ALAT, ASAT, INR) and mortality. A strong genotype-phenotype correlation was demonstrated in individuals sharing the same genotype; this was especially true for the ILFS2 subgroup. Genotype-phenotype correlation in patients sharing only one missense variant was still high, though at a lower level. Pre-symptomatic diagnosis in combination with an emergency management protocol leads to a trend of reduced severity of ALF. High genetic impact on clinical phenotype in NBAS-associated disease facilitates monitoring and management of affected patients sharing the same genotype. Pre-symptomatic diagnosis and an emergency management protocol do not prevent ALF but may reduce its clinical severity.

Abstract
PURPOSE We used next-generation sequencing (NGS) to investigate the genetic causes of suspected genetic short stature in 37 patients, and we describe their phenotypes and various genetic spectra. METHODS We reviewed the medical records of 50 patients who underwent genetic testing using NGS for suspected genetic short stature from June 2019 to December 2022. Patients with short stature caused by nongenetic factors or common chromosomal abnormalities were excluded. Thirty-seven patients from 35 families were enrolled in this study. We administered one of three genetic tests (2 targeted panel tests or whole exome sequencing) to patients according to their phenotypes. RESULTS Clinical and molecular diagnoses were confirmed in 15 of the 37 patients, for an overall diagnostic yield of 40.5%. Fifteen pathogenic/likely pathogenic variants were identified in 13 genes (ACAN, ANKRD11, ARID1B, CEP152, COL10A1, COL1A2, EXT1, FGFR3, NIPBL, NRAS, PTPN11, SHOX, SLC16A2). The diagnostic rate was highest in patients who were small for their gestational age (7 of 11, 63.6%). CONCLUSION Genetic evaluation using NGS can be helpful in patients with suspected genetic short stature who have clinical and genetic heterogeneity. Further studies are needed to develop patient selection algorithms and panels containing growth-related genes.

Abstract
Intrauterine onset syndromic short stature constitutes a group of diseases that pose challenges in differential diagnosis due to their rarity and clinical as well as molecular heterogeneity. The aim of this study was to investigate the presence of (epi)genetic causes in children born small for gestational age (SGA) and manifesting clinically undiagnosed syndromic short stature. The study group comprised twenty-nine cases selected from the syndromic SGA cohort. Various analyses were performed, including chromosomal microarray (CMA), methylation-specific-multiple ligation probe amplification for chromosomes 6,14 and 20, and whole exome sequencing (WES). Pathogenic copy number variants (CNVs) on chromosomes 2q13, 22q11.3, Xp22.33, 17q21.31, 19p13.13 and 4p16.31 causing syndromic growth disturbance were detected in six patients. Maternal uniparental disomy 14 was identified in a patient. WES was performed in the remaining 22 patients, revealing pathogenic variants in nine cases; six were monoallelic (ACAN, ARID2, NIPBL, PIK3R1, SMAD4, BRIP1), two were biallelic (BRCA2, RFWD3) and one was hemizygous (HUWE1). Seven of these were novel. Craniofacial dysmorphism, which is an important clue for the diagnosis of syndromes, was very mild in all patients. This study unveiled, for the first time, that ARID2 mutatios can cause syndromic SGA. In conclusion, a high (55.2%) diagnosis rate was achieved through the utilization of CMA, epigenetic and WES analyzes; 15 rare syndromes were defined, who were born with SGA and had atypical and/or mild dysmorphic findings. This study not only drew attention to the association of some rare syndromes with SGA, but also introduced novel genes and CNVs as potential contributors to syndromic SGA.

Abstract
The most common causes of short stature (SS) in children are familial short stature (FSS) and idiopathic short stature (ISS). Recently, growth plate dysfunction has been recognized as the genetic cause of FSS or ISS. The aim of this study was to investigate monogenic growth failure in patients with ISS and FSS. Targeted exome sequencing was performed in patients categorized as ISS or FSS and the subsequent response to growth hormone (GH) therapy was analyzed. We found 17 genetic causes involving 12 genes (NPR2, IHH, BBS1, COL1A1, COL2A1, TRPS1, MASP1, SPRED1, PTPTN11, ADNP, NADSYN1, and CERT1) and 2 copy number variants. A genetic cause was found in 45.5% and 35.7% of patients with FSS and ISS, respectively. The genetic yield in patients with syndromic and non-syndromic SS was 90% and 23.1%, respectively. In the 11 genetically confirmed patients, a gain in height from -2.6 to -1.3 standard deviations after 2 years of GH treatment was found. The overall diagnostic yield in this study was 41.7%. We identified several genetic causes involving paracrine signaling, the extracellular matrix, and basic intracellular processes. Identification of the causative gene may provide prognostic evidence for the use of GH therapy in non-SGA children.

Abstract
High-throughput sequencing has become a standard first-tier approach for both diagnostics and research-based genetic testing. Consequently, this hypothesis-free testing manner has revealed the true breadth of clinical features for many established genetic disorders, including Meier-Gorlin syndrome (MGORS). Previously known as ear-patella short stature syndrome, MGORS is characterized by growth delay, microtia, and patella hypo/aplasia, as well as genital abnormalities, and breast agenesis in females. Following the initial identification of genetic causes in 2011, a total of 13 genes have been identified to date associated with MGORS. In this review, we summarise the genetic and clinical findings of each gene associated with MGORS and highlight molecular insights that have been made through studying patient variants. We note interesting observations arising across this group of genes as the number of patients has increased, such as the unusually high number of synonymous variants affecting splicing in CDC45 and a subgroup of genes that also cause craniosynostosis. We focus on the complicated molecular genetics for DONSON, where we examine potential genotype-phenotype patterns using the first 3D structural model of DONSON. The canonical role of all proteins associated with MGORS are involved in different stages of DNA replication and in addition to summarising how patient variants impact on this process, we discuss the potential contribution of non-canonical roles of these proteins to the pathophysiology of MGORS.

Abstract
Since the first report of SOPH syndrome among the Yakut population in 2010, new clinical data of SOPH-like conditions continue to appear. We expand the phenotypic spectrum of SOPH syndrome and perform a comparative analysis of Yakut SOPH patients' clinical data with SOPH-like conditions reported in the world scientific literature to form a foundation for NBAS pathogenesis discussion. Clinical data from the genetic records of 93 patients with SOPH syndrome and global survey data on patients with pathogenic variants of the C-terminal in the NBAS gene were collected. A detailed phenotype description of patients is presented with a total number of 111 individuals. Underweight below the fifth centile and prone to delayed bone age in Yakut SOPH patients are retrospectively observed. We outline the short stature with optic atrophy as the leading phenotyping trait for C-terminal NBAS patients. The pathophysiology and patients management of SOPH-like conditions are discussed.

Wit JM, Joustra SD. Long-acting PEGylated growth hormone in children with idiopathic short stature: time to reconsider our diagnostic and treatment policy? Eur J Endocrinol 2023; 188:6979711.

Abstract
Idiopathic short stature (ISS) is a diagnosis of exclusion, and therefore each child with short stature or slow growth referred to a paediatrician deserves a full medical history and physical examination, as well as radiological and laboratory screening tests. In patients with an increased likelihood of a genetic cause, genetic testing is indicated. Idiopathic short stature is an approved indication for recombinant human growth hormone (rhGH) in the USA but not in most other parts of the world. In a recent article published in this journal, Luo et al reported on the 1-year's results of a multicentre randomized controlled trial (n = 360) on the efficacy and safety of two dosages of long-acting PEGylated rhGH (PEG-rhGH, Jintrolong®) (0.1 or 0.2 mg/kg body weight per week, respectively) in children with ISS compared with an untreated control group. The growth response to the higher dosage was similar to reported data on daily rhGH. In this commentary, we discuss whether the recent data on genetic causes of short stature in children who initially were labelled ISS, and data on the long-term safety of daily rhGH, may influence the balance between risks and benefits of rhGH treatment in children with ISS. We further discuss the pharmacokinetic and -dynamic profile of PEG-rhGH and its potential consequences for long-term safety.

Abstract
We investigated the distribution of short stature-associated mutations in Korean pediatric patients with idiopathic short stature (ISS) and isolated growth hormone deficiency (IGHD) via targeted next-generation sequencing (TNGS). We employed a 96-gene TNGS panel for short stature in a total of 144 patients (5-19 years-old) previously diagnosed with ISS or IGHD and identified heterozygous pathogenic or likely pathogenic genetic variants in 14 (10%) patients. Of the mutated genes, PROKR2 (n = 3) is associated with gonadotropin-releasing hormone deficiency or hypopituitarism, while FGFR1 (n = 1) and NPR2 (n = 3) encode growth plate paracrine factors. FBN1 (n = 1), COL9A1 (n = 1), MATN3 (n = 1), and ACAN (n = 3) regulate the cartilage extracellular matrix, while PTPN11 (n = 1) controls intracellular pathways. Six patients had IGHD, and eight patients had ISS. The current findings highlight the utility of TNGS for determining the genetic etiology in these patients.

Abstract
BACKGROUND Sotos syndrome is an autosomal dominant disorder characterized by overgrowth, macrocephaly, distinctive facial features and learning disabilities. Haploinsufficiency of the nuclear receptor SET domain-containing protein 1 (NSD1) gene located on chromosome 5q35 is the major cause of the syndrome. This syndrome shares characteristics with other overgrowth syndromes, which can complicate the differential diagnosis. METHODS Genomic DNA was extracted from peripheral blood samples of members of the same family and targeted exome analysis was performed. In silico study of the variant found by next-generation sequencing was used to predict disruption/creation of splice sites and the identification of potential cryptic splice sites. RNA was extracted from peripheral blood samples of patients and functional analyses were performed to confirm the pathogenicity. RESULTS We found a novel c.6463 + 5G>A heterozygous NSD1 gene pathogenic variant in a son and his father. Molecular analyses revealed that part of the intron 22 of NSD1 is retained due to the destruction of the splicing donor site, causing the appearance of a premature stop codon in the NSD1 protein. CONCLUSIONS Our findings underline the importance of performing RNA functional assays in order to determine the clinical significance of intronic variants, and contribute to the genetic counseling and clinical management of patients and their relatives. Our work also highlights the relevance of using in silico prediction tools to detect a potential alteration in the splicing process.

Abstract
BACKGROUND Large-scale genomic analyses have provided insight into the genetic complexity of short stature (SS); however, only a portion of genetic causes have been identified. In this study, we identified disease-causing mutations in a cohort of Korean patients with suspected syndromic SS by targeted exome sequencing (TES). METHODS Thirty-four patients in South Korea with suspected syndromic disorders based on abnormal growth and dysmorphic facial features, developmental delay, or accompanying anomalies were enrolled in 2018-2020 and evaluated by TES. RESULTS For 17 of 34 patients with suspected syndromic SS, a genetic diagnosis was obtained by TES. The mean SDS values for height, IGF-1, and IGFBP-3 for these 17 patients were - 3.27 ± 1.25, - 0.42 ± 1.15, and 0.36 ± 1.31, respectively. Most patients displayed distinct facial features (16/17) and developmental delay or intellectual disability (12/17). In 17 patients, 19 genetic variants were identified, including 13 novel heterozygous variants, associated with 15 different genetic diseases, including many inherited rare skeletal disorders and connective tissue diseases (e.g., cleidocranial dysplasia, Hajdu-Cheney syndrome, Sheldon-Hall, acromesomelic dysplasia Maroteaux type, and microcephalic osteodysplastic primordial dwarfism type II). After re-classification by clinical reassessment, including family member testing and segregation studies, 42.1% of variants were pathogenic, 42.1% were likely pathogenic variant, and 15.7% were variants of uncertain significance. Ultra-rare diseases accounted for 12 out of 15 genetic diseases (80%). CONCLUSIONS A high positive result from genetic testing suggests that TES may be an effective diagnostic approach for patients with syndromic SS, with implications for genetic counseling. These results expand the mutation spectrum for rare genetic diseases related to SS in Korea.

Abstract
Next-generation sequencing (NGS) technologies have changed the process of genetic diagnosis from a gene-by-gene approach to syndrome-based diagnostic gene panel sequencing (DPS), diagnostic exome sequencing (DES), and diagnostic genome sequencing (DGS). A priori information on the causative genes that might underlie a genetic condition is a prerequisite for genetic diagnosis before conducting clinical NGS tests. Theoretically, DPS, DES, and DGS do not require any information on specific candidate genes. Therefore, clinical NGS tests sometimes detect disease-related pathogenic variants in genes underlying different conditions from the initial diagnosis. These clinical NGS tests are expensive, but they can be a cost-effective approach for the rapid diagnosis of rare disorders with genetic heterogeneity, such as the glycogen storage disease, familial intrahepatic cholestasis, lysosomal storage disease, and primary immunodeficiency. In addition, DES or DGS may find novel genes that that were previously not linked to human diseases.

Abstract
Biallelic variants in neuroblastoma-amplified sequence (NBAS) cause an extremely broad spectrum of phenotypes. Clinical features range from isolated recurrent episodes of liver failure to multisystemic syndrome including short stature, skeletal osteopenia and dysplasia, optic atrophy, and a variable immunological, cutaneous, muscular, and neurological abnormalities. Hemizygous variants in CUL4B cause syndromic X-linked intellectual disability characterized by limitations in intellectual functions, developmental delays in gait, cognitive, and speech functioning, and other features including short stature, dysmorphism, and cerebral malformations. In this study, we report on a 4.5-month-old preterm infant with a complex phenotype mainly characterized by placental-related severe intrauterine growth restriction, post-natal growth failure with spontaneous bone fractures, which led to a suspicion of osteogenesis imperfecta, and lethal bronchopulmonary dysplasia with pulmonary hypertension. Whole exome sequencing identified compound heterozygosity for a known frameshift and a novel missense variant in NBAS and hemizygosity for a known CUL4B nonsense mutation. In vitro functional studies on the novel NBAS missense substitution demonstrated altered Golgi-to-endoplasmic reticulum retrograde vesicular trafficking and reduced collagen secretion, likely explaining part of the patient's phenotype. We also provided a comprehensive overview of the phenotypic features of NBAS and CUL4B deficiency, thus updating the recently emerging NBAS genotype-phenotype correlations. Our findings highlight the power of a genome-first approach for an early diagnosis of complex phenotypes.

Abstract
AIM Neuroblastoma amplified sequence (NBAS)-associated disease has a wide phenotypic spectrum, including infantile liver failure syndrome type 2 (ILFS2, OMIM #616483), short stature with optic nerve atrophy and Pelger-Huët anomaly (SOPH) syndrome (OMIM #614800), and a combined phenotype overlapping ILFS2 and SOPH syndrome. The mutation spectra of NBAS and its genotype-phenotype correlation among Chinese were not clear. METHODS Clinical and genetic data were retrospectively collected from the medical charts of patients with biallelic NBAS mutations, as well as from Chinese patients in previously published reports. RESULTS Fourteen new patients were identified, including 10 novel mutations: c.648-1G>A, c.2563_c.2577+5del/p.His855_Gln859del, c.3115C>T/p.Gln1039Ter, c.3284G>A/p.Trp1095Ter, c.2570C>T/p.Ala857Val, c.6859G>T/p.Asp2287Tyr, c.1028G>A/p.Ser343Asn, c.1177_1182delinsAGATAGA/p.Val393ArgfsTer2, c.3432_3435dupCAGT/p.Ala1146GlnfsTer14, and c.680_690dupACTGTTTCAGC/p.Phe231ThrfsTer35. All 14 patients presented as fever-triggered liver injury, including nine patients that satisfied the criteria of acute liver failure (ALF) in whom c.3596G>A/p.Cys1199Tyr occurred five times. Nine patients had extrahepatic manifestations including short stature, skeletal abnormalities, intellectual disability, ophthalmic abnormalities, low levels of serum immunoglobulins, facial dysmorphism, and cardiac abnormalities. Ten other Chinese patients were collected through a review of published works. Genotype-phenotype analysis in 24 Chinese patients revealed that the percentage of ALF patients with variants in the Sec39 domain was significantly higher than that in the C-terminal (100% vs. 12.5%, P = 0.000), and the percentage of multi-organ/system involvement in patients with variants in the Sec39 domain was significantly lower than that in the C-terminal (40% vs. 100%, P = 0.0128). CONCLUSIONS We reported 14 new patients, 10 novel mutations, and a unique recurrent mutation. Correlation analysis indicated that the domain of missense and non-frameshift insertion/deletion mutations in NBAS protein is related to phenotype among Chinese patients.

Abstract
BACKGROUND Floating-Harbor syndrome (FHS) is a rare condition characterized by dysmorphic facial features, short stature, and expressive language delay. OBJECTIVE The aim of this study was to describe a cohort of patients with FHS and review the literature about the response to recombinant human growth hormone (rhGH) therapy. METHODS Anthropometric and laboratory data from 7 patients with FHS were described. The molecular diagnosis was established by multigene analysis. Moreover, we reviewed the literature concerning patients with FHS treated with rhGH. RESULTS All 7 patients were born small for gestational age. At first evaluation, 6 patients had a height standard deviation score (SDS) ≤-2 and 1 had short stature in relation to their target height. Bone age was usually delayed, which rapidly advanced during puberty. Nonspecific skeletal abnormalities were frequently noticed, and normal to elevated plasma IGF-I levels were observed in all except 1 patient with growth hormone deficiency. Information about 20 patients with FHS treated with rhGH was analyzed (4 from our cohort and 16 from the literature). The median height changes during the treatment period (approx. 2.9 years) were 1.1 SDS (range from -0.4 to 3.1). Nontreated patients had an adult height SDS of -4.1 ± 1.2 (n = 10) versus -2.6 ± 0.8 SDS (n = 7, p 0.012) for treated patients. CONCLUSION We observed a laboratory profile compatible with IGF-1 insensitivity in some patients with FHS. Nevertheless, our study suggests that children with FHS may be considered as candidates for rhGH therapy. Further studies are necessary to establish the real benefit and safety of rhGH therapy in these patients.

Abstract
Autosomal recessive SOPH syndrome was first described in the Yakuts population of Asia by Maksimova et al. in 2010. It arises from biallelic pathogenic variants in the NBAS gene and is characterized by severe postnatal growth retardation, senile facial appearance, small hands and feet, optic atrophy with loss of visual acuity and color vision, and normal intelligence (OMIM #614800). The presence of Pelger-Hüet anomaly in this disorder led to its name as an acronym for Short stature, Optic nerve atrophy, and Pelger-Hüet anomaly. Recent publications have further contributed to the characterization of this syndrome through additional phenotype-genotype correlations. We review the clinical features described in these publications and report on a 27-year-old woman with dwarfism with osteolysis and multiple skeletal problems, minor anomalies, immunodeficiency, diabetes mellitus, and multiple secondary medical problems. Her condition was considered an unknown autosomal recessive disorder for many years until exome sequencing provided the diagnosis by revealing a founder disease-causing variant that was compound heterozygous with a novel pathogenic variant in NBAS. Based on the major clinical features of this individual and others reported earlier, a revision of the acronym is warranted to facilitate clinical recognition.

Abstract
Disease-causing variants in TGFB3 cause an autosomal dominant connective tissue disorder which is hard to phenotypically delineate because of the small number of identified cases. The purpose of this retrospective cross-sectional multicenter study is to elucidate the genotype and phenotype in an international cohort of TGFB3 patients. Eleven (eight novel) TGFB3 disease-causing variants were identified in 32 patients (17 families). Aortic root dilatation and mitral valve disease represented the most common cardiovascular findings, reported in 29% and 32% of patients, respectively. Dissection involving distal aortic segments occurred in two patients at age 50 and 52 years. A high frequency of systemic features (65% high-arched palate, 63% arachnodactyly, 57% pectus deformity, 52% joint hypermobility) was observed. In familial cases, incomplete penetrance and variable clinical expressivity were noted. Our cohort included the first described homozygous patient, who presented with a more severe phenotype compared to her heterozygous relatives. In conclusion, TGFB3 variants were associated with a high percentage of systemic features and aortic disease (dilatation/dissection) in 35% of patients. No deaths occurred from cardiovascular events or pregnancy-related complications. Nevertheless, homozygosity may be driving a more severe phenotype.

Genetic Disorders in Prenatal Onset Syndromic Short Stature Identified by Exome Sequencing. J Pediatr 2019; 215:192-198. [PMID: 31630891 DOI: 10.1016/j.jpeds.2019.08.024] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2019] [Revised: 06/25/2019] [Accepted: 08/09/2019] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To perform a prospective genetic investigation using whole exome sequencing of a group of patients with syndromic short stature born small for gestational age of unknown cause. STUDY DESIGN For whole exome sequencing analysis, we selected 44 children born small for gestational age with persistent short stature, and additional features, such as dysmorphic face, major malformation, developmental delay, and/or intellectual disability. Seven patients had negative candidate gene testing based on clinical suspicion and 37 patients had syndromic conditions of unknown etiology. RESULTS Of the 44 patients, 15 (34%) had pathogenic/likely pathogenic variants in genes already associated with growth disturbance: COL2A1 (n = 2), SRCAP (n = 2), AFF4, ACTG1, ANKRD11, BCL11B, BRCA1, CDKN1C, GINS1, INPP5K, KIF11, KMT2A, and POC1A (n = 1 each). Most of the genes found to be deleterious participate in fundamental cellular processes, such as cell replication and DNA repair. CONCLUSIONS The rarity and heterogeneity of syndromic short stature make the clinical diagnosis difficult. Whole exome sequencing allows the diagnosis of previously undiagnosed patients with syndromic short stature.

Abstract
Craniosynostosis is a pathologic craniofacial disorder and is defined as the premature fusion of one or more cranial (calvarial) sutures. Cranial sutures are fibrous joints consisting of nonossified mesenchymal cells that play an important role in the development of healthy craniofacial skeletons. Early fusion of these sutures results in incomplete brain development that may lead to complications of several severe medical conditions including seizures, brain damage, mental delay, complex deformities, strabismus, and visual and breathing problems. As a congenital disease, craniosynostosis has a heterogeneous origin that can be affected by genetic and epigenetic alterations, teratogens, and environmental factors and make the syndrome highly complex. To date, approximately 200 syndromes have been linked to craniosynostosis. In addition to being part of a syndrome, craniosynostosis can be nonsyndromic, formed without any additional anomalies. More than 50 nuclear genes that relate to craniosynostosis have been identified. Besides genetic factors, epigenetic factors like microRNAs and mechanical forces also play important roles in suture fusion. As craniosynostosis is a multifactorial disorder, evaluating the craniosynostosis syndrome requires and depends on all the information obtained from clinical findings, genetic analysis, epigenetic or environmental factors, or gene modulators. In this review, we will focus on embryologic and genetic studies, as well as epigenetic and environmental studies. We will discuss published studies and correlate the findings with unknown aspects of craniofacial disorders.

Abstract
CONTEXT Patients born small for gestational age (SGA) who present with persistent short stature could have an underlying genetic etiology that will account for prenatal and postnatal growth impairment. We applied a unique massive parallel sequencing approach in cohort of patients with exclusively nonsyndromic SGA to simultaneously interrogate for clinically substantial genetic variants. OBJECTIVE To perform a genetic investigation of children with isolated short stature born SGA. DESIGN Screening by exome (n = 16) or targeted gene panel (n = 39) sequencing. SETTING Tertiary referral center for growth disorders. PATIENTS AND METHODS We selected 55 patients born SGA with persistent short stature without an identified cause of short stature. MAIN OUTCOME MEASURES Frequency of pathogenic findings. RESULTS We identified heterozygous pathogenic or likely pathogenic genetic variants in 8 of 55 patients, all in genes already associated with growth disorders. Four of the genes are associated with growth plate development, IHH (n = 2), NPR2 (n = 2), SHOX (n = 1), and ACAN (n = 1), and two are involved in the RAS/MAPK pathway, PTPN11 (n = 1) and NF1 (n = 1). None of these patients had clinical findings that allowed for a clinical diagnosis. Seven patients were SGA only for length and one was SGA for both length and weight. CONCLUSION These genomic approaches identified pathogenic or likely pathogenic genetic variants in 8 of 55 patients (15%). Six of the eight patients carried variants in genes associated with growth plate development, indicating that mild forms of skeletal dysplasia could be a cause of growth disorders in this group of patients.

Abstract
The dosage of the serine threonine kinase DYRK1A is critical in the central nervous system (CNS) during development and aging. This review analyzes the functions of this kinase by considering its interacting partners and pathways. The role of DYRK1A in controlling the differentiation of prenatal newly formed neurons is presented separately from its role at the pre- and post-synaptic levels in the adult CNS; its effects on synaptic plasticity are also discussed. Because this kinase is positioned at the crossroads of many important processes, genetic dosage errors in this protein produce devastating effects arising from DYRK1A deficiency, such as in MRD7, an autism spectrum disorder, or from DYRK1A excess, such as in Down syndrome. Effects of these errors have been shown in various animal models including Drosophila, zebrafish, and mice. Dysregulation of DYRK1A levels also occurs in neurodegenerative diseases such as Alzheimer's and Parkinson's diseases. Finally, this review describes inhibitors that have been assessed in vivo. Accurate targeting of DYRK1A levels in the brain, with either inhibitors or activators, is a future research challenge.

Abstract
Male infertility is a complex multifactorial disease affecting approximately 10% of couples who want to have children. Some cases of infertility can be explained by genetic factors. Septins are members of the GTPase superfamily, which are involved in diverse biological processes including morphogenesis, compartmentalization, cytokinesis, and apoptosis. The septin 12 gene, SEPT12, is expressed exclusively in post-meiotic male germ cells and is considered as a critical gene for spermatogenesis. In this study, we evaluated 200 patients with non-obstructive azoospermia and detected mutations of 25 spermatogenesis-associated genes by targeted exome sequencing. We report a missense SEPT12 variant, c.673C>A/p.Gln225Lys, in an infertile man with non-obstructive azoospermia. The variation was located inside the GTPase domain and had a SIFT score of 0.02 (<0.50) and was considered to be 'probably damaging' by PolyPhen. This case may provide clues to help establish the relationship between SEPT12 gene alterations and some cases of idiopathic male infertility. The role of this variant should thus be investigated further.

Abstract
BACKGROUND Nonobstructive azoospermia (NOA) is one of the most severe forms of male infertility because of impaired spermatogenesis with the absence of spermatozoa in the ejaculate. The causes of this disease can be partly attributed to genetic factors. Some common structural variants and single nucleotide polymorphisms (SNPs) were reported to be associated with NOA. However, the underlying etiology and genetic mechanism(s) remain largely unclear. The aim of this study was to investigate the associated mutations of spermatogenic genes in Chinese infertile men with NOA. METHODS The entire coding region of 25 genes associated with spermatogenesis was sequenced from 200 infertile men with NOA. Screening was carried out using the targeted exome sequencing to identify genetic variations and SNPs of the entire coding region of these genes. RESULTS After the targeted exome sequencing data were filtered through several currently existing variation databases, a series of variations were found. In this paper, we report one novel stopgain variation c.G992A (p.W331X) in the exon 4 of TACR3 gene. The variant was heterozygous and categorized as pathogenic. CONCLUSION In conclusion, our study revealed a novel stopgain mutation c.G992A (p.W331X) in TACR3 which expanded the mutation spectrum of TACR3 in Chinese NOA infertile men and advanced our understanding of the genetic susceptibility to NOA.
