Abstract: Summary: Histone deacetylases play crucial roles in the regulation of chromatin structure and gene expression in the eukaryotic cell, and disruption of their activity causes a wide range of developmental disorders in humans. Loss-of-function alleles of HDAC4, a founding member of the class IIa deacetylases, have been reported in brachydactyly-mental retardation syndrome (BDMR). However, while disruption of HDAC4 activity and deregulation of its downstream targets may contribute to the BDMR phenotype, loss of HDAC4 function usually occurs as part of larger deletions of chromosome 2q37; BDMR is also known as chromosome 2q37 deletion syndrome, and the precise role of HDAC4 within the phenotype remains uncertain. Thus, identification of missense variants should shed new light on the role of HDAC4 in normal development. Here, we report seven unrelated individuals with a phenotype distinct from that of BDMR, all of whom have heterozygous de novo missense variants that affect a major regulatory site of HDAC4, required for signal-dependent 14-3-3 binding and nucleocytoplasmic shuttling. Two individuals possess variants altering Thr244 or Glu247, whereas the remaining five all carry variants altering Pro248, a key residue for 14-3-3 binding. We propose that the variants in all seven individuals impair 14-3-3 binding (as confirmed for the first two variants by immunoprecipitation assays), thereby identifying deregulation of HDAC4 as a pathological mechanism in a previously uncharacterized developmental disorder.

Abstract: Abstract Background Fumarate hydratase (FH) deficiency is a rare autosomal recessive disorder which results in a major defect in cellular metabolism. It presents in infancy with progressive encephalopathy, hypotonia, seizures and failure to thrive and is often fatal in childhood. It is caused by mutations in the FH gene (1q42.1) that result in deficiency of the citric acid cycle enzyme fumarate hydratase, resulting in accumulation of fumaric acid. Heterozygous germline mutations in the FH gene predispose to an aggressive autosomal dominant inherited early-onset kidney cancer syndrome: hereditary leiomyomatosis and renal cell cancer (HLRCC). Case presentation Cascade FH mutation screening enabled the early diagnosis of a renal tumour in an asymptomatic parent of a child with fumarate hydratase deficiency, resulting in timely and possibly life-saving treatment. Conclusion While the theoretical risk of kidney cancer in parents of children with recessive fumarate hydratase deficiency is well recognized, to our knowledge this is the first report of a kidney tumour being detected in a parent by screening performed for this indication. This underscores the importance of offering lifelong kidney surveillance to such parents and other heterozygous relatives of children born with fumarate hydratase deficiency.

Abstract: Context Differences of sex development (DSD) represent a wide range of conditions presenting at different ages to various health professionals. Establishing a diagnosis, supporting the family, and developing a management plan are important. Objective We aimed to better understand the presentation and prevalence of pediatric DSD. Methods A retrospective, observational cohort study was undertaken in a single tertiary pediatric center of all children and young people (CYP) referred to a DSD multidisciplinary team over 25 years (1995-2019). In total, 607 CYP (520 regional referrals) were included. Data were analyzed for diagnosis, sex-assignment, age and mode of presentation, additional phenotypic features, mortality, and approximate point prevalence. Results Among the 3 major DSD categories, sex chromosome DSD was diagnosed in 11.2% (68/607) (most commonly 45,X/46,XY mosaicism), 46,XY DSD in 61.1% (371/607) (multiple diagnoses often with associated features), while 46,XX DSD occurred in 27.7% (168/607) (often 21-hydroxylase deficiency). Most children (80.1%) presented as neonates, usually with atypical genitalia, adrenal insufficiency, undescended testes or hernias. Those presenting later had diverse features. Rarely, the diagnosis was made antenatally (3.8%, n = 23) or following incidental karyotyping/family history (n = 14). Mortality was surprisingly high in 46,XY children, usually due to complex associated features (46,XY girls, 8.3%; 46,XY boys, 2.7%). The approximate point prevalence of neonatal referrals for investigation of DSD was 1 in 6347 births, and 1 in 5101 overall throughout childhood. Conclusion DSD represent a diverse range of conditions that can present at different ages. Pathways for expert diagnosis and management are important to optimize care.

Abstract: AimsThis study assesses the diagnostic utility of whole genome sequence analysis in a well-characterised research cohort of individuals referred with a clinical suspicion of Cornelia de Lange syndrome (CdLS) in whom prior genetic testing had not identified a causative variant.MethodsShort read, whole genome sequencing was performed in 195 individuals from 105 families, 108 of whom were affected. 100/108 of the affected individuals had prior relevant genetic testing with no pathogenic variant being identified. The study group comprised 42 trios (affected individuals with both unaffected parents), 61 singletons (unrelated affected individuals) and two families with more than one affected individual.Results32/105 (30.5%) unrelated probands had likely causative coding region disrupting variants. 4 loci were identified in >1 proband; NIPBL (10), ANKRD11 (6), EP300 (3), EHMT1 (2). Single alleles were detected in the remaining genes (EBF3, KMT2A, MED13L, NLGN3, NR2F1, PHIP, PUF60, SET, SETD5, SMC1A, TBL1XR1). Possibly causative variants in non-coding regions of NIPBL were identified in four individuals. Single de novo variants were identified in five genes not previously reported to be associated with any developmental disorder: ARID3A, PIK3C3, MCM7, MIS18BP1 and WDR18.ConclusionsClustering of de novo non-coding variants implicate a single uORF and a small region in intron 21 in NIPBL regulation. Causative variants in genes encoding chromatin-associated proteins, with no defined influence on cohesin function, appear to result in CdLS-like clinical features.

7. De Novo PTEN Mutation in a Young Boy with Cutaneous Vasculitis

Author: Angela Mauro, Ebun Omoyinmi, Neil James Sebire, Angela Barnicoat, and Paul Brogan
Subjects: Pediatrics, RJ1-570
Abstract: Phosphatase and tensin homolog (PTEN) is the protein encoded by the PTEN gene (10q23.3). PTEN mutations are related to a variety of rare diseases referred to collectively as PTEN hamartoma tumor syndromes (PHTS), which include Cowden Syndrome, Bannayan-Riley-Ruvalcaba syndrome, Proteus Syndrome, and Proteus-like syndrome. These diseases are associated with an increased risk of malignancy and for this reason an accurate and early diagnosis is essential in order to institute cancer surveillance. PTEN is a regulator of growth and homeostasis in immune system cells, although there are limited data describing immune dysregulation caused by PTEN mutations. We describe a case of PHTS syndrome caused by a de novo mutation in PTEN detected using a targeted next generation sequencing (NGS) gene panel which was instigated for workup of cutaneous vasculitis. We highlight the diagnostic utility of this approach and that mutations in PTEN may be associated with immune-dysregulatory features such as vasculitis in young children.

Abstract: Rapid technological advances in genomic testing continue to increase our understanding of the genetic basis of a wide range of kidney disorders. Establishing a molecular diagnosis benefits the individual by bringing an end to what is often a protracted diagnostic odyssey, facilitates accurate reproductive counselling for families and, in the future, is likely to lead to the delivery of more targeted management and surveillance regimens. The selection of the most appropriate testing modality requires an understanding both of the technologies available and of the genetic architecture and heterogeneity of kidney disease. Whilst we are witnessing a far greater diagnostic yield with broader genetic testing, such approaches invariably generate variants of uncertain significance and secondary incidental findings, which are not only difficult to interpret but present ethical challenges with reporting and feeding back to patients and their families. Here, we review the spectrum of nephrogenetic disorders, consider the optimal approach to genetic testing, explore the clinical utility of obtaining a molecular diagnosis, reflect on the challenges of variant interpretation and look to the future of this dynamic field.

Abstract: Spondylometaphyseal dysplasia with cerebral hypomyelination (SMD-H) is a very rare but distinctive phenotype, unusually combining spondylometaphyseal dysplasia with hypomyelinating leukodystrophy. Recently, SMD-H has been associated with variants confined to a specific intra-genic locus involving Exon 7, suggesting that AIFM1 plays an important role in bone development and metabolism as well as cerebral myelination. Here we describe two further affected boys, one with a novel intronic variant associated with skipping of Exon 7 of AIFM1 and the other a synonymous variant within Exon 7 of AIFM1. We describe their clinical course and radiological and genetic findings, providing further insight into the natural history of this condition.

Abstract: SummaryMutation in the germline is the source of all evolutionary genetic variation and a cause of genetic disease. Previous studies have shown parental age to be the primary determinant of the number of new germline mutations seen in an individual’s genome. Here we analysed the genome-wide sequences of 21,879 families with rare genetic diseases and identified 12 hypermutated individuals with between two and seven times more de novo single nucleotide variants (dnSNVs) than expected. In most of these families (8/12) the excess mutations could be attributed to the father. We determined that two of these families had genetic drivers of germline hypermutation, with the fathers carrying damaging genetic variation in known DNA repair genes, causing distinctive mutational signatures. For five families, by analysing clinical records and mutational signatures, we determined that paternal exposure to chemotherapeutic agents prior to conception was a key driver of hypermutation. Our results suggest that the germline is well protected from mutagenic effects, hypermutation is rare and relatively modest in degree and that most hypermutated individuals will not have a genetic disease.

Abstract: Summary Histone deacetylases play crucial roles in the regulation of chromatin structure and gene expression in the eukaryotic cell, and disruption of their activity causes a wide range of developmental disorders in humans. Loss-of-function alleles of HDAC4, a founding member of the class IIa deacetylases, have been reported in brachydactyly-mental retardation syndrome (BDMR). However, while disruption of HDAC4 activity and deregulation of its downstream targets may contribute to the BDMR phenotype, loss of HDAC4 function usually occurs as part of larger deletions of chromosome 2q37; BDMR is also known as chromosome 2q37 deletion syndrome, and the precise role of HDAC4 within the phenotype remains uncertain. Thus, identification of missense variants should shed new light on the role of HDAC4 in normal development. Here, we report seven unrelated individuals with a phenotype distinct from that of BDMR, all of whom have heterozygous de novo missense variants that affect a major regulatory site of HDAC4, required for signal-dependent 14-3-3 binding and nucleocytoplasmic shuttling. Two individuals possess variants altering Thr244 or Glu247, whereas the remaining five all carry variants altering Pro248, a key residue for 14-3-3 binding. We propose that the variants in all seven individuals impair 14-3-3 binding (as confirmed for the first two variants by immunoprecipitation assays), thereby identifying deregulation of HDAC4 as a pathological mechanism in a previously uncharacterized developmental disorder., Loss-of-function variants in histone deacetylase 4 (HDAC4) have been reported to cause brachydactyly-mental retardation (BDMR) syndrome through haploinsufficiency. This report describes 7 individuals with a phenotype distinct from BDMR, all with missense variants in a conserved 14-3-3 site, which are hypothesized to result in a novel gain-of-function effect in HDAC4.

Abstract: Pathogenic variants in ZMYND11, which acts as a transcriptional repressor, have been associated with intellectual disability, behavioural abnormalities and seizures. Only 11 affected individuals have been reported to‐date, and the phenotype associated with pathogenic variants in this gene have not been fully defined.\ud \ud Here, we present 16 additional patients with predicted pathogenic heterozygous variants in ZMYND11, including four individuals from the same family, to further delineate and expand the genotypic and phenotypic spectrum of ZMYND11‐related syndromic intellectual disability. The associated phenotype includes developmental delay, particularly affecting speech, mild‐moderate intellectual disability, significant behavioural abnormalities, seizures, and hypotonia. There are subtle shared dysmorphic features, including prominent eyelashes and eyebrows, depressed nasal bridge with bulbous nasal tip, anteverted nares, thin vermilion of the upper lip and wide mouth. Novel features include brachydactyly and tooth enamel hypoplasia.\ud \ud Most identified variants are likely to result in premature truncation and/or nonsense mediated decay. Two ZMYND11 variants located in the final exon ‐ p.(Gln586*) (likely escaping nonsense‐mediated decay) and p.(Cys574Arg) ‐ are predicted to disrupt the MYND‐type zinc finger motif and likely interfere with binding to its interaction partners. Hence, the homogeneous phenotype likely results from a common mechanism of loss‐of‐function.

Abstract: International audience; EML1 encodes the protein Echinoderm microtubule-associated protein-like 1 or EMAP-1 that binds to the microtubule complex. Mutations in this gene resulting in complex brain malformations have only recently been published with limited clinical descriptions. We provide further clinical and imaging details on three previously published families, and describe two novel unrelated individuals with a homozygous partial EML1 deletion and a homozygous missense variant c.760G>A, p.(Val254Met), respectively. From review of the clinical and imaging data of eight individuals from five families with biallelic EML1 variants, a very consistent imaging phenotype emerges. The clinical syndrome is characterized by mainly neurological features including severe developmental delay, drug-resistant seizures and visual impairment. On brain imaging there is megalencephaly with a characteristic ribbon-like subcortical heterotopia combined with partial or complete callosal agenesis and an overlying polymicrogyria-like cortical malformation. Several of its features can be recognized on prenatal imaging especially the abnormaly formed lateral ventricles, hydrocephalus (in half of the cases) and suspicion of a neuronal migration disorder. In conclusion, biallelic EML1 disease-causing variants cause a highly specific pattern of congenital brain malformations, severe developmental delay, seizures and visual impairment.

Abstract: Fragile X syndrome (FXS) is a triplet-repeat expansion disorder of the X chromosome, with repeats of more than 200 (sometimes referred to as the full mutation) causing FXS and ∼59–200 repeats (the so-called premutation) being responsible for a variety of clinical presentations. Clinicians in primary care should be aware of these conditions and in particular be vigilant for common comorbidities to allow for early treatment. This article summarises the common issues for individuals with FXS and carriers of the premutation. FXS is the most common inherited cause of intellectual disability, occurring in approximately 1 in 3000–4000 males and 1 in 6000–8000 females. Although the genetic underpinnings of FXS are similar across individuals, the manifestations vary widely and in some ways there is no ‘typical’ presentation. Nonetheless, males with the syndrome generally have an intellectual disability ranging from mild to severe, whereas females are much more variably affected (due to random X-inactivation) and can range from being essentially asymptomatic to having a severe intellectual disability. There are a number of common physical comorbidities associated with the syndrome including epilepsy (∼25%), mitral valve prolapse (≤80%), hyperextensible joints, and an increased risk of inguinal hernias. Anxiety, attention deficit hyperactivity disorder (ADHD), and autism spectrum disorders (ASDs) are also significantly more common. Hyperarousal and sensory hypersensitivity are frequent symptoms, which may occur across a range of diagnoses. It is worth noting that, although one-third to two-thirds of individuals with FXS may meet criteria for an ASD, the presentation often varies subtly from that seen in idiopathic ASDs. In particular, some traits such as social difficulties and atypical eye contact may have very different underpinnings in FXS as compared with ASDs. …

Abstract: Congenital contractural arachnodactyly (CCA) is an autosomal dominant connective tissue disorder manifesting joint contractures, arachnodactyly, crumpled ears, and kyphoscoliosis as main features. Due to its rarity, rather aspecific clinical presentation, and overlap with other conditions including Marfan syndrome, the diagnosis is challenging, but important for prognosis and clinical management. CCA is caused by pathogenic variants in FBN2, encoding fibrillin-2, but locus heterogeneity has been suggested. We designed a clinical scoring system and diagnostic criteria to support the diagnostic process and guide molecular genetic testing., info:eu-repo/semantics/published

Abstract: Contains fulltext : 206572.pdf (Publisher’s version ) (Open Access) We delineate a KMT2E-related neurodevelopmental disorder on the basis of 38 individuals in 36 families. This study includes 31 distinct heterozygous variants in KMT2E (28 ascertained from Matchmaker Exchange and three previously reported), and four individuals with chromosome 7q22.2-22.23 microdeletions encompassing KMT2E (one previously reported). Almost all variants occurred de novo, and most were truncating. Most affected individuals with protein-truncating variants presented with mild intellectual disability. One-quarter of individuals met criteria for autism. Additional common features include macrocephaly, hypotonia, functional gastrointestinal abnormalities, and a subtle facial gestalt. Epilepsy was present in about one-fifth of individuals with truncating variants and was responsive to treatment with anti-epileptic medications in almost all. More than 70% of the individuals were male, and expressivity was variable by sex; epilepsy was more common in females and autism more common in males. The four individuals with microdeletions encompassing KMT2E generally presented similarly to those with truncating variants, but the degree of developmental delay was greater. The group of four individuals with missense variants in KMT2E presented with the most severe developmental delays. Epilepsy was present in all individuals with missense variants, often manifesting as treatment-resistant infantile epileptic encephalopathy. Microcephaly was also common in this group. Haploinsufficiency versus gain-of-function or dominant-negative effects specific to these missense variants in KMT2E might explain this divergence in phenotype, but requires independent validation. Disruptive variants in KMT2E are an under-recognized cause of neurodevelopmental abnormalities.

Abstract: © 2019 American Society of Human Genetics The occurrence of non-epileptic hyperkinetic movements in the context of developmental epileptic encephalopathies is an increasingly recognized phenomenon. Identification of causative mutations provides an important insight into common pathogenic mechanisms that cause both seizures and abnormal motor control. We report bi-allelic loss-of-function CACNA1B variants in six children from three unrelated families whose affected members present with a complex and progressive neurological syndrome. All affected individuals presented with epileptic encephalopathy, severe neurodevelopmental delay (often with regression), and a hyperkinetic movement disorder. Additional neurological features included postnatal microcephaly and hypotonia. Five children died in childhood or adolescence (mean age of death: 9 years), mainly as a result of secondary respiratory complications. CACNA1B encodes the pore-forming subunit of the pre-synaptic neuronal voltage-gated calcium channel Cav2.2/N-type, crucial for SNARE-mediated neurotransmission, particularly in the early postnatal period. Bi-allelic loss-of-function variants in CACNA1B are predicted to cause disruption of Ca2+ influx, leading to impaired synaptic neurotransmission. The resultant effect on neuronal function is likely to be important in the development of involuntary movements and epilepsy. Overall, our findings provide further evidence for the key role of Cav2.2 in normal human neurodevelopment.

Abstract: Histone lysine methyltransferases (KMTs) and demethylases (KDMs) underpin gene regulation. Here we demonstrate that variants causing haploinsufficiency of KMTs and KDMs are frequently encountered in individuals with developmental disorders. Using a combination of human variation databases and existing animal models, we determine 22 KMTs and KDMs as additional candidates for dominantly inherited developmental disorders. We show that KMTs and KDMs that are associated with, or are candidates for, dominant developmental disorders tend to have a higher level of transcription, longer canonical transcripts, more interactors, and a higher number and more types of post-translational modifications than other KMT and KDMs. We provide evidence to firmly associate KMT2C, ASH1L, and KMT5B haploinsufficiency with dominant developmental disorders. Whereas KMT2C or ASH1L haploinsufficiency results in a predominantly neurodevelopmental phenotype with occasional physical anomalies, KMT5B mutations cause an overgrowth syndrome with intellectual disability. We further expand the phenotypic spectrum of KMT2B-related disorders and show that some individuals can have severe developmental delay without dystonia at least until mid-childhood. Additionally, we describe a recessive histone lysine-methylation defect caused by homozygous or compound heterozygous KDM5B variants and resulting in a recognizable syndrome with developmental delay, facial dysmorphism, and camptodactyly. Collectively, these results emphasize the significance of histone lysine methylation in normal human development and the importance of this process in human developmental disorders. Our results demonstrate that systematic clinically oriented pathway-based analysis of genomic data can accelerate the discovery of rare genetic disorders.

Abstract: Although ribosomes are ubiquitously expressed and essential for life, recent data indicate that monogenic causes of ribosomal dysfunction can confer a remarkable degree of specificity in terms of human disease phenotype. Box C/D small nucleolar RNAs (snoRNAs) are evolutionarily conserved non-protein encoding RNAs involved in ribosome biogenesis. Here we show that biallelic mutations in the gene SNORD118, encoding the box C/D snoRNA U8, cause the cerebral microangiopathy leukoencephalopathy with calcifications and cysts (LCC), presenting at any age from early childhood to late adulthood. These mutations affect U8 expression, processing and protein binding and thus implicate U8 as essential in cerebral vascular homeostasis.

Abstract: Item does not contain fulltext Histone lysine methylation, mediated by mixed-lineage leukemia (MLL) proteins, is now known to be critical in the regulation of gene expression, genomic stability, cell cycle and nuclear architecture. Despite MLL proteins being postulated as essential for normal development, little is known about the specific functions of the different MLL lysine methyltransferases. Here we report heterozygous variants in the gene KMT2B (also known as MLL4) in 27 unrelated individuals with a complex progressive childhood-onset dystonia, often associated with a typical facial appearance and characteristic brain magnetic resonance imaging findings. Over time, the majority of affected individuals developed prominent cervical, cranial and laryngeal dystonia. Marked clinical benefit, including the restoration of independent ambulation in some cases, was observed following deep brain stimulation (DBS). These findings highlight a clinically recognizable and potentially treatable form of genetic dystonia, demonstrating the crucial role of KMT2B in the physiological control of voluntary movement.

Abstract: Lenz-Majewski syndrome (LMS) is a syndrome of intellectual disability and multiple congenital anomalies that features generalized craniotubular hyperostosis. By using whole-exome sequencing and selecting variants consistent with the predicted dominant de novo etiology of LMS, we identified causative heterozygous missense mutations in PTDSS1, which encodes phosphatidylserine synthase 1 (PSS1). PSS1 is one of two enzymes involved in the production of phosphatidylserine. Phosphatidylserine synthesis was increased in intact fibroblasts from affected individuals, and end-product inhibition of PSS1 by phosphatidylserine was markedly reduced. Therefore, these mutations cause a gain-of-function effect associated with regulatory dysfunction of PSS1. We have identified LMS as the first human disease, to our knowledge, caused by disrupted phosphatidylserine metabolism. Our results point to an unexplored link between phosphatidylserine synthesis and bone metabolism.

Abstract: Although ribosomes are ubiquitous and essential for life, recent data indicate that monogenic causes of ribosomal dysfunction can confer a remarkable degree of specificity in terms of human disease phenotype. Box C/D small nucleolar RNAs (snoRNAs) are evolutionarily conserved non-protein-coding RNAs involved in ribosome biogenesis. Here we show that biallelic mutations in the gene SNORD118, encoding the box C/D snoRNA U8, cause the cerebral microangiopathy leukoencephalopathy with calcifications and cysts (LCC), presenting at any age from early childhood to late adulthood. These mutations affect U8 expression, processing and protein binding and thus implicate U8 as essential in cerebral vascular homeostasis.

Abstract: Background: Coexistence of congenital adrenal hyperplasia (CAH) and congenital hypothyroidism (CH) due to TG mutation in the same non-consanguineous family is rare. Case Series: We report 4 siblings born to unrelated parents, the father being an asymptomatic carrier of homozygous p.V281L and heterozygous p.I172N CYP21A2 mutations. Sibling 1 had salt-wasting CAH (CYP21A2 genotype Intron 2 splice/p.I172N and p.V281L). She also had CH (TG genotype p.R296/ p.T1416Rfs*30) and learning difficulties. Poor compliance and morbid obesity resulted in short stature, precocious puberty, hirsutism, amenorrhoea, insulin insensitivity and a possible adrenal adenoma. Sibling 3 (CYP21A2 and TG genotype similar to sibling 1) is a boy presenting with salt-wasting CAH, CH, and developmental delay. He was overweight and underwent precocious puberty. Although siblings 2 and 4 (both females) share the same CYP21A2 genotype (Intron 2 splice/p.V281L), the former only had biochemical evidence of CAH, while the latter presented at 9.8 years of age with a history of pubarche at 7 years and advanced bone age. Conclusions: We report the unusual occurrence of 2 rare autosomal recessive diseases, CAH and CH. Our cases highlight the phenotypic variability of CAH and CH due to TG mutations, even within a single family, and illustrate the importance of optimal disease control.

Abstract: Purpose. Sex chromosome trisomies (SCTs) are found on amniocentesis in 2.3 to 3.7 per 1000 same-sex births, yet there is a limited database on which to base a prognosis. Autism has been described in post-natally diagnosed cases of Klinefelter syndrome (XXY karyotype), but the prevalence in non-referred samples, and in other trisomies, is unclear. We recruited the largest sample including all three SCTs to be reported to date, including children identified on prenatal screening, to clarify this issue.Design. Parents of children with a SCT were recruited either via prenatal screening or via a parental support group, to give a sample of 58 XXX, 19 XXY, and 58 XYY cases. Parents were interviewed using the Vineland Adaptive Behavior Scales and completed questionnaires about the communicative development of children with SCTs and their siblings (42 brothers and 26 sisters).Results. Rates of language and communication problems were high in all three trisomies. Diagnoses of autism spectrum disorder (ASD) were found in 2/19 cases of XXY (11%) and 11/58 XYY (19%). After excluding those with an ASD diagnosis, communicative profiles indicative of mild autistic features were common, although there was wide individual variation.Conclusions. Autistic features have not previously been remarked upon in studies of non-referred samples with SCTs, yet the rate is substantially above population levels in this sample, even when attention is restricted to early-identified cases. We hypothesise that X- and Y-linked neuroligins may play a significant role in the etiology of communication impairments and ASD.

Abstract: We have cloned the fragile site FRAXE and demonstrate that individuals with this fragile site possess amplifications of a GCC repeat adjacent to a CpG island in Xq28 of the human X chromosome. Normal individuals have 6-25 copies of the GCC repeat, whereas mentally retarded, FRAXE-positive individuals have > 200 copies and also have methylation at the CpG island. This situation is similar to that seen at the FRAXA locus and is another example in which a trinucleotide repeat expansion is associated with a human genetic disorder. In contrast with the fragile X syndrome, the GCC repeat can expand or contract and is equally unstable when passed through the male or female line. These results also have implications for the understanding of chromosome fragility.

Abstract: Human ciliopathies are hereditary conditions caused by defects of proteins expressed at the primary cilium. Among ciliopathies, Joubert syndrome and related disorders (JSRD), Meckel syndrome (MKS) and nephronophthisis (NPH) present clinical and genetic overlap, being allelic at several loci. One of the most interesting gene is TMEM67, encoding the transmembrane protein meckelin. We performed mutation analysis of TMEM67 in 341 probands, including 265 JSRD representative of all clinical subgroups and 76 MKS fetuses. We identified 33 distinct mutations, of which 20 were novel, in 8/10 (80%) JS with liver involvement (COACH phenotype) and 12/76 (16%) MKS fetuses. No mutations were found in other JSRD subtypes, confirming the strong association between TMEM67 mutations and liver involvement. Literature review of all published TMEM67 mutated cases was performed to delineate genotype-phenotype correlates. In particular, comparison of the types of mutations and their distribution along the gene in lethal versus non lethal phenotypes showed in MKS patients a significant enrichment of missense mutations falling in TMEM67 exons 8 to 15, especially when in combination with a truncating mutation. These exons encode for a region of unknown function in the extracellular domain of meckelin.

Abstract: Disorder of sex development (DSD) presents a unique challenge, both diagnostically and in terms of acute and longer-term management. These are relatively rare conditions usually requiring a multidisciplinary approach from the outset and the involvement of a tertiary centre for assessment and management recommendations. This article describes the structure of the multidisciplinary team (MDT) at our centre, with contributions from key members of the team regarding their individual roles. The focus is on the newborn referred for assessment of ambiguous genitalia, rather than on individuals who present in the adolescent period or at other times, although the same MDT involvement is likely to be required. The approach to the initial assessment and management is discussed and the subsequent diagnosis and follow-up presented, with emphasis on the importance of careful transition and long-term support.

Abstract: Duplications of distal 8p with and without significant clinical phenotypes have been reported and are often associated with an unusual degree of structural complexity. Here, we present a duplication of 8p23.1-8p23.2 ascertained in a child with speech delay and a diagnosis of ICD-10 autism. The same duplication was found in his mother who had epilepsy and learning problems. A combination of cytogenetic, FISH, microsatellite, MLPA and oaCGH analysis was used to show that the duplication extended over a minimum of 6.8 Mb between 3 539 893 and 10 323 426 bp. This interval contains 32 novel and 41 known genes, of which only microcephalin (MCPH1) is a plausible candidate gene for autism at present. The distal breakpoint of the duplicated region interrupts the CSMD1 gene in 8p23.2 and the medial breakpoint lies between the MSRA and RP1L1 genes in 8p23.1.An interchromosomal insertion between a normal and polymorphically inverted chromosome 8 is proposed to explain the origin of this duplication. Further mapped imbalances of distal 8p are needed to determine whether the autistic component of the phenotype in this family results from the cumulative imbalance of many genes or dosage imbalance of an individual susceptibility gene.

Abstract: Cerebro-Costo-Mandibular syndrome (CCMS) is a rare autosomal dominant condition comprising branchial arch-derivative malformations with striking rib-gaps. Affected patients often have respiratory difficulties, associated with upper airway obstruction, reduced thoracic capacity, and scoliosis. We describe a series of 12 sporadic and 4 familial patients including 13 infants/children and 3 adults. Severe micrognathia and reduced numbers of ribs with gaps are consistent findings. Cleft palate, feeding difficulties, respiratory distress, tracheostomy requirement, and scoliosis are common. Additional malformations such as horseshoe kidney, hypospadias, and septal heart defect may occur. Microcephaly and significant developmental delay are present in a small minority of patients. Key radiological findings are of a narrow thorax, multiple posterior rib gaps and abnormal costo-transverse articulation. A novel finding in 2 patients is bilateral accessory ossicles arising from the hyoid bone. Recently, specific mutations in SNRPB, which encodes components of the major spliceosome, have been found to cause CCMS. These mutations cluster in an alternatively spliced regulatory exon and result in altered SNRPB expression. DNA was available from 14 patients and SNRPB mutations were identified in 12 (4 previously reported). Eleven had recurrent mutations previously described in patients with CCMS and one had a novel mutation in the alternative exon. These results confirm the specificity of SNRPB mutations in CCMS and provide further evidence for the role of spliceosomal proteins in craniofacial and thoracic development.

Abstract: A family with midline nasal dermoids in four members over five generations is described. Two of these individuals also had a midline cleft lip. The pattern of inheritance appears to be autosomal dominant with variable expression. To our knowledge, no familial cases of midline clefting with nasal dermoids have previously been reported in the literature. Cranial imaging to look for intracerebral extension of the dermoid is recommended in such cases.

Abstract: We report the case of a girl who has joint and skin laxity with atrophic scarring, and was diagnosed at birth with a Dandy-Walker malformation. She subsequently developed joint contractures, hydrocephalus and syringomyelia. This case shows some similarities to Ehlers-Danlos syndrome type VI, but with no evidence of lysyl hydroxylase deficiency or ocular fragility. It is likely that she represents a distinct and recognizable syndrome. There was parental consanguinity and a subsequent pregnancy resulted in a similarly affected fetus, suggesting autosomal recessive inheritance.

Abstract: Branchio-oto-renal (BOR) syndrome is an autosomal dominant disorder involving hearing loss, branchial defects, ear pits and renal abnormalities. Oto-facio-cervical (OFC) syndrome is clinically similar to BOR syndrome, with clinical features in addition to those of BOR syndrome. Mutations in the EYA1 gene (localised to 8q13.3) account for nearly 70% of BOR syndrome cases exhibiting at least three of the major features. Small intragenic deletions of the 3' region of the gene have also been reported in patients with BOR syndrome. We have developed a fluorescent quantitative multiplex polymerase chain reaction for three 3' exons (7, 9 and 13) of the EYA1 gene. This dosage assay, combined with microsatellite marker analysis, has identified de novo deletions of the EYA1 gene and surrounding region in two patients with complex phenotypes involving features of BOR syndrome. One patient with OFC syndrome carried a large deletion of the EYA1 gene region, confirming that OFC syndrome is allelic with BOR syndrome. Microsatellite analysis has shown that comparison of the boundaries of this large deletion with other reported rearrangements of the region reduces the critical region for Duane syndrome (an eye movement disorder) to between markers D8S553 and D8S1797, a genetic distance of approximately 1 cM.

Abstract: Imprinting in 15q11-q13 is controlled by a bipartite imprinting center (IC), which maps to the SNURF-SNRPN locus. Deletions of the exon 1 region impair the establishment or maintenance of the paternal imprint and can cause Prader-Willi syndrome (PWS). Deletions of a region 35 kb upstream of exon 1 impair maternal imprinting and can cause Angelman syndrome (AS). So far, in all affected sibs with an imprinting defect, an inherited IC deletion was identified. We report on two sibs with AS who do not have an IC deletion but instead have a 1-1.5 Mb inversion separating the two IC elements. The inversion is transmitted silently through the male germline but impairs maternal imprinting after transmission through the female germline. Our findings suggest that the close proximity and/or the correct orientation of the two IC elements are/is necessary for the establishment of a maternal imprint.

Abstract: Item does not contain fulltext Microscopically visible distal 8p deletions have been associated with growth and mental impairment, minor facial anomalies, congenital heart defects, and behavioral problems. We report two cousins with mild retardation and behavioral problems, including inappropriate sexual behavior and pyromania. Familial learning difficulties on the grandfather's side incompatible with Mendelian inheritance prompted telomere screening, which detected a submicroscopic terminal 8p deletion of < 5.1 Mb. The cousins' mothers both carried a t(8;20)(p23;p13) balanced translocation. The frequently observed microcephaly in patients with microscopically visible deletions of 8pter is lacking in both cousins, suggesting that the gene(s) causing the microcephaly is centromeric to the deleted region. The absence of cardiac defects in the cousins confirms the more proximal location of gene(s) causing these abnormalities in other reported cases with microscopically visible 8pter deletions and supports involvement of the GATA4 gene. Moreover, the current cases predict the presence of a putative gene(s) involved in behavior in the most telomeric 5.1 Mb of the p-arm of chromosome 8. This first clinical report of a submicroscopic subtelomeric 8p deletion gives more insight into the so-called 8p- syndrome and demonstrates the difficulty in making a clinical diagnosis for a submicroscopic 8pter deletion in an individual patient with mental retardation.

Abstract: Piebaldism is an autosomal dominant disorder, characterized by congenital leukoderma typically on the abdomen, knees, and forehead. Mice models for human piebaldism are the W dominant white spotting, the steel mice and the mice that are mutated for the slug gene. Human genes for these mice models were investigated in this study. Genomic DNAs of peripheral leukocytes were prepared from twenty-two patients with piebaldism. PCR-direct sequencing or screening by SSCP and subsequent sequencing of all of the exons and flanking introns of KIT, SCF (stem cell factor), and SLUG genes disclosed six pathological mutations only in KIT. Among them five were novel: 358delG, IVS3-2A>G, Q346X, H650L, and D792Y. His650 is located in the strand connecting the helix αC and the downstream β-sheet of the N-lobe of the active KIT kinase domain, the crystal fine structure of which was determined recently. Asp792 is situated in the center of the kinase active site of interdomain cleft between the N-lobe and the C-lobe. No pathological mutations were found in SCF or SLUG in our screening system. Analysis of mutations in the KIT kinase domain may offer an insight into the detailed functional role of this fascinating protein.

Abstract: Sotos syndrome is characterized by overgrowth, a typical facial appearance, and learning difficulties. It is caused by heterozygous mutations, including deletions, of NSD1 located at chromosome 5q35. Here we report two unrelated cases of Sotos syndrome associated with nephrocalcinosis. One patient also had idiopathic infantile hypercalcemia. Genetic investigations revealed heterozygous deletions at 5q35 in both patients, encompassing NSD1 and SLC34A1 (NaPi2a). Mutations in SLC34A1 have previously been associated with hypercalciuria/nephrolithiasis. Our cases suggest a contiguous gene deletion syndrome including NSD1 and SLC34A1 and provide a potential genetic basis for idiopathic infantile hypercalcemia.

Abstract: Arthrogryposis, Renal dysfunction and Cholestasis (ARC) syndrome is a multi-system autosomal recessive disorder caused by germline mutations in VPS33B. The detection of germline VPS33B mutations removes the need for diagnostic organ biopsies (these carry a >50% risk of life-threatening haemorrhage due to platelet dysfunction); however, VPS33B mutations are not detectable in similar to 25% of patients. In order further to define the molecular basis of ARC we performed mutation analysis and mRNA and protein studies in patients with a clinical diagnosis of ARC. Here we report novel mutations in VPS33B in patients from Eastern Europe and South East Asia. One of the mutations was present in 7 unrelated Korean patients. Reduced expression of VPS33B and cellular phenotype was detected in fibroblasts from patients clinically diagnosed with ARC with and without known VPS33B mutations. One mutation-negative patient was found to have normal mRNA and protein levels. This patient's clinical condition improved and he is alive at the age of 2.5 years. Thus we show that all patients with a classical clinical course of ARC had decreased expression of VPS33B whereas normal VPS33B expression was associated with good prognosis despite initial diagnosis of ARC.

Abstract: Ciliopathies are an expanding group of rare conditions characterized by multiorgan involvement, that are caused by mutations in genes encoding for proteins of the primary cilium or its apparatus. Among these genes, CEP290 bears an intriguing allelic spectrum, being commonly mutated in Joubert syndrome and related disorders (JSRD), Meckel syndrome (MKS), Senior-Loken syndrome and isolated Leber congenital amaurosis (LCA). Although these conditions are recessively inherited, in a subset of patients only one CEP290 mutation could be detected. To assess whether genomic rearrangements involving the CEP290 gene could represent a possible mutational mechanism in these cases, exon dosage analysis on genomic DNA was performed in two groups of CEP290 heterozygous patients, including five JSRD/ MKS cases and four LCA, respectively. In one JSRD patient, we identified a large heterozygous deletion encompassing CEP290 C -terminus that resulted in marked reduction of mRNA expression. No copy number alterations were identified in the remaining probands. The present work expands the CEP290 genotypic spectrum to include multiexon deletions. Although this mechanism does not appear to be frequent, screening for genomic rearrangements should be considered in patients in whom a single CEP290 mutated allele was identified.

Abstract: Background : Piebaldism is an autosomal dominantly inherited disorder characterized by congenital leukoderma, typically on the forehead, abdomen, and knees. The leukoderma is usually stable throughout life. KIT mutations have been demonstrated in about 75% of patients with piebaldism. Objectives : To identify KIT mutations of the family with piebaldism and examine genotype-phenotype correlations in this disorder. Methods : PCR-direct-sequencing technique using genomic DNA from peripheral leukocytes. Results : We have studied 10 individuals within six piebaldism families and able to identify six novel mutations in the KIT gene in patients with piebaldism. These include four frameshift mutations: 142delG, 1768–1769delAG, 2139delC, 2246–2249delAAAG, and two missense mutations: M541L, Y870C. Conclusions : These six new mutations are associated with phenotypes that are well in accordance with our knowledge of genotype-phenotype correlations in KIT .

Abstract: Imprinting on human chromosome 15q11-q13 is controlled by a bipartite imprinting center (IC) that maps to the SNRPN locus. Deletions of the IC result in an imprinting defect and Prader-Willi syndrome or Angelman syndrome (AS). We have now identified a 5-kb IC deletion in an English AS patient (AS-LO); this represents the smallest microdeletion found in AS and narrows down the shortest region of deletion overlap to 880 bp.

Abstract: This case series describes four males who presented with learning and behavioural difficulties. In each case, the diagnosis of fragile X syndrome was delayed because of an initial false-negative cytogenetic result. Although most children are currently investigated for fragile X syndrome using highly sensitive and specific molecular techniques, there still remain a large number of older children who have been tested using only cytogenetic analysis. The clinical presentation of these four children and the reason for the occurrence of the false-negative results are considered. In addition, there is a discussion and illustration of how a screening checklist can be used to help clinicians to decide which children should be retested.

Abstract: Meckel syndrome (MKS) is a lethal malformation syndrome characterised by posterior meningoencephalocele, polycystic kidneys, fibrotic changes of the liver, and polydactyly. We have previously shown a linkage to chromosome 17q in 17 Finnish Meckel families. In this study we have analysed one Italian, one Austrian (of Turkish origin) and three British MKS families (Caucasian, Pakistani, and Bangladeshi families) for linkage to the MKS locus on chromosome 17q22–q24. We did not observe co-segregation of the disease and marker haplotypes in the Austrian family or in the three British families, of which two represented classical MKS and one a slightly atypical MKS phenotype with longer survival of the patient. In the Italian family the affected and non-affected children did not share the same maternal chromosome and thus this family could represent the same allelic disease as the Finnish MKS families. These results suggest locus heterogeneity in Meckel syndrome – a feature previously suspected based on the highly variable clinical phenotype.
