9. Possible incomplete penetrance of Xq28 int22h‐1/int22h‐2 duplication.

Subjects: HOMOLOGOUS recombination, FACIAL abnormalities, INTELLECTUAL disabilities, DISEASE relapse, UNIVERSITY hospitals
Abstract: Xq28 int22h‐1/int22h‐2 duplication is the result of non‐allelic homologous recombination between int22h‐1/int22h‐2 repeats separated by 0.5 Mb. It is responsible for a syndromic form of intellectual disability (ID), with recurrent infections and atopic diseases. Minor defects, nonspecific facial dysmorphic features, and overweight have also been described. Half of female carriers have been reported with ID, whereas all reported evaluated born males present mild to moderate ID, suggesting complete penetrance. We collected data on 15 families from eight university hospitals. Among them, 40 patients, 21 females (one fetus), and 19 males (two fetuses), were carriers of typical or atypical Xq28 int22h‐1/int22h‐2 duplication. Twenty‐one individuals were considered asymptomatic (16 females and 5 males), without significantly higher rate of recurrent infections, atopia, overweight, or facial dysmorphism. Approximately 67% live‐born males and 23% live‐born female carriers of the typical duplication did not have obvious signs of intellectual disability, suggesting previously undescribed incomplete penetrance or low expression in certain carriers. The possibility of a second‐hit or modifying factors to this possible susceptibility locus is yet to be studied but a possible observational bias should be considered in assessing such challenging X‐chromosome copy number gains. Additional segregation studies should help to quantify this newly described incomplete penetrance. [ABSTRACT FROM AUTHOR]

Subjects: *PHENOTYPES, *VARICOSE veins, *ANGIOMYOLIPOMA
Abstract: This article discusses the clinical phenotype of the PIK3R1-related vascular overgrowth syndrome, which is a subset of the PIK3CA-related overgrowth spectrum (PROS). The study found that variants in the PIK3R1 gene were present in a minority of patients with PROS-like phenotypes, accounting for about 7% of cases. These variants were more commonly associated with Klippel-Trénaunay syndrome (KTS) rather than the megalencephaly-capillary malformation (MCAP) phenotype. The article suggests expanding the definition of PROS to include both PIK3CA and PIK3R1-related phenotypes. [Extracted from the article]

Subjects: HYPOPIGMENTATION, FOCAL cortical dysplasia, HUMAN abnormalities, NEURAL development, MEDICAL genetics, DYSPLASIA
Abstract: This article discusses a case of a patient with postzygotic MTOR-related hypomelanosis of Ito and neurodevelopmental abnormalities. The patient had hemimegalencephaly, developmental delay, mild intellectual disability, and behavioral disorders. The study found high variability in the variant allele fraction (VAF) in different tissues, which was not correlated with clinical features. The patient died at the age of 33, likely due to a fatal epileptic seizure. The presence of the MTOR mutation was found in the cerebral cortex, tongue, pancreas, and left kidney, but not in other organs. The article highlights the allelic heterogeneity in different tissues and the lack of correlation between VAF and clinical features. The risk of sudden unexpected death in epilepsy (SUDEP) was also discussed, but further confirmation is needed. The authors express gratitude to the patient's parents for their consent to publish the findings. [Extracted from the article]

Abstract: You‐Hoover‐Fong syndrome (YHFS) is an autosomal recessive condition caused by pathogenic variants in the TELO2 gene. Affected individuals were reported to have global developmental delay, intellectual disability, microcephaly, dysmorphic facial features, ocular involvement including cortical visual impairment, strabismus, cataract and rotatory nystagmus, movement disorder, hypertonia and spasticity, balance disturbance and ataxia, and abnormal sleep pattern. Other features reported include poor growth, cleft palate, cardiac malformations, epilepsy, scoliosis, and hearing loss. To date, 12 individuals with YHFS have been reported in the literature. Here we describe 14 new individuals with YHFS from 10 families. Their clinical presentation provides additional support of the phenotype recognized previously and delineates the clinical spectrum associated with YHFS syndrome. In addition, we present a review of the literature including follow‐up data on four previously reported individuals with YHFS. [ABSTRACT FROM AUTHOR]

Abstract: A small but growing body of scientific literature is emerging about clinical findings in patients with 19p13.3 microdeletion or duplication. Recently, a proximal 19p13.3 microduplication syndrome was described, associated with growth delay, microcephaly, psychomotor delay and dysmorphic features. The aim of our study was to better characterize the syndrome associated with duplications in the proximal 19p13.3 region (prox 19p13.3 dup), and to propose a comprehensive analysis of the underlying genomic mechanism. We report the largest cohort of patients with prox 19p13.3 dup through a collaborative study. We collected 24 new patients with terminal or interstitial 19p13.3 duplication characterized by array‐based Comparative Genomic Hybridization (aCGH). We performed mapping, phenotype–genotype correlations analysis, critical region delineation and explored three‐dimensional chromatin interactions by analyzing Topologically Associating Domains (TADs). We define a new 377 kb critical region (CR 1) in chr19: 3,116,922–3,494,377, GRCh37, different from the previously described critical region (CR 2). The new 377 kb CR 1 includes a TAD boundary and two enhancers whose common target is PIAS4. We hypothesize that duplications of CR 1 are responsible for tridimensional structural abnormalities by TAD disruption and misregulation of genes essentials for the control of head circumference during development, by breaking down the interactions between enhancers and the corresponding targeted gene.

28. Evidence for high breakpoint variability in 46, XX, SRY‐positive testicular disorder and frequent ARSE deletion that may be associated with short stature.

Subjects: Y chromosome, SHORT stature, X chromosome, SEX differentiation disorders, CHROMOSOMAL rearrangement, DELETION mutation
Abstract: Background: The translocation of SRY onto one of the two X chromosomes results in a 46,XX testicular disorder of sex development; this is supposedly because of non‐allelic homologous recombination between the protein kinase X gene (PRKX) and the inverted protein kinase Y pseudogene (PRKY). Although 46,XX SRY‐positive men are infertile, the literature data indicate that some of these individuals are of short stature (relative to the general population). We sought to determine whether short stature was linked to additional, more complex chromosomal rearrangements. Methods: Twelve laboratories gathered detailed clinical, anthropomorphic, cytogenetic and genetic data (including chromosome microarray data) on patients with 46,XX SRY‐positive male syndrome. Results: SRY was present (suggesting a der(X)t(X;Y)) in 34 of the 38 cases (89.5%). When considering only the 20 patients with chromosome microarray data, we identified several chromosomal rearrangements and breakpoints, especially on the X chromosome. In the five cases for whom the X chromosome breakpoint was located in the pseudoautosomal region, there was partial duplication of the derivate X chromosome. In contrast, in the 15 cases for whom the breakpoint was located downstream of the pseudoautosomal region, part of the derivate X chromosome had been deleted (included the arylsulfatase E [ARSE] gene in 11 patients). For patients with versus without ARSE deletion, the mean height was, respectively, 167.7 ± 4.5 and 173.1 ± 4.0 cm; this difference was not statistically significant (p = 0.1005). Conclusion: Although 46,XX SRY‐positive male syndromes were mainly because of imbalanced crossover between the X and Y chromosome during meiosis, the breakpoints differed markedly from one patient to another (especially on the X chromosome); this suggests the presence of a replication‐based mechanism for recombination between non‐homologous sequences. In some patients, the translocation of SRY to the X chromosome was associated with ARSE gene deletion, which might have led to short stature. With a view to explaining this disorder of sex development, whole exome sequencing could be suggested for SRY‐negative patients. [ABSTRACT FROM AUTHOR]

Subjects: HIDDEN Markov models, DNA copy number variations, COMPARATIVE genomic hybridization, GENETIC variation
Abstract: It has been estimated that Copy Number Variants (CNVs) account for 10%–20% of patients affected by Developmental Disorder (DD)/Intellectual Disability (ID). Although array comparative genomic hybridization (array‐CGH) represents the gold‐standard for the detection of genomic imbalances, common Agilent array‐CGH 4 × 180 kb arrays fail to detect CNVs smaller than 30 kb. Whole Exome sequencing (WES) is becoming the reference application for the detection of gene variants and makes it possible also to infer genomic imbalances at single exon resolution. However, the contribution of small CNVs in DD/ID is still underinvestigated. We made use of the eXome Hidden Markov Model (XHMM) software, a tool utilized by the ExAC consortium, to detect CNVs from whole exome sequencing data, in a cohort of 200 unsolved DD/DI patients after array‐CGH and WES‐based single nucleotide/indel variant analyses. In five out of 200 patients (2.5%), we identified pathogenic CNV(s) smaller than 30 kb, ranging from one to six exons. They included two heterozygous deletions in TCF4 and STXBP1 and three homozygous deletions in PPT1, CLCN2, and PIGN. After reverse phenotyping, all variants were reported as causative. This study shows the interest in applying sequencing‐based CNV detection, from available WES data, to reduce the diagnostic odyssey of additional patients unsolved DD/DI patients and compare the CNV‐detection yield of Agilent array‐CGH 4 × 180kb versus whole exome sequencing.

Subjects: MEDICAL personnel, PROFESSIONS, DELPHI method, EXPERTISE
Abstract: Growth promoting variants in PIK3CA cause a spectrum of developmental disorders, depending on the developmental timing of the mutation and tissues involved. These phenotypically heterogeneous entities have been grouped as PIK3CA‐Related Overgrowth Spectrum disorders (PROS). Deep sequencing technologies have facilitated detection of low‐level mosaic, often necessitating testing of tissues other than blood. Since clinical management practices vary considerably among healthcare professionals and services across different countries, a consensus on management guidelines is needed. Clinical heterogeneity within this spectrum leads to challenges in establishing management recommendations, which must be based on patient‐specific considerations. Moreover, as most of these conditions are rare, affected families may lack access to the medical expertise that is needed to help address the multi‐system and often complex medical issues seen with PROS. In March 2019, macrocephaly‐capillary malformation (M‐CM) patient organizations hosted an expert meeting in Manchester, United Kingdom, to help address these challenges with regards to M‐CM syndrome. We have expanded the scope of this project to cover PROS and developed this consensus statement on the preferred approach for managing affected individuals based on our current knowledge.

Abstract: Aminoacyl‐tRNA synthetases (aaRS) are ubiquitously expressed enzymes responsible for ligating amino acids to their cognate tRNA molecules through an aminoacylation reaction. The resulting aminoacyl‐tRNA is delivered to ribosome elongation factors to participate in protein synthesis. Seryl‐tRNA synthetase (SARS1) is one of the cytosolic aaRSs and catalyzes serine attachment to tRNASer. SARS1 deficiency has already been associated with moderate intellectual disability, ataxia, muscle weakness, and seizure in one family. We describe here a new clinical presentation including developmental delay, central deafness, cardiomyopathy, and metabolic decompensation during fever leading to death, in a consanguineous Turkish family, with biallelic variants (c.638G>T, p.(Arg213Leu)) in SARS1. This missense variant was shown to lead to protein instability, resulting in reduced protein level and enzymatic activity. Our results describe a new clinical entity and expand the clinical and mutational spectrum of SARS1 and aaRS deficiencies. [ABSTRACT FROM AUTHOR]

Subjects: NEURAL development, EPHRIN receptors, EPHRINS, PROTEIN-tyrosine kinases, SIZE of brain
Abstract: Ephrin receptor and their ligands, the ephrins, are widely expressed in the developing brain. They are implicated in several developmental processes that are crucial for brain development. Deletions in genes encoding for members of the Eph/ephrin receptor family were reported in several neurodevelopmental disorders. The ephrin receptor A7 gene (EPHA7) encodes a member of ephrin receptor subfamily of the protein‐tyrosine kinase family. EPHA7 plays a role in corticogenesis processes, determines brain size and shape, and is involved in development of the central nervous system. One patient only was reported so far with a de novo deletion encompassing EPHA7 in 6q16.1. We report 12 additional patients from nine unrelated pedigrees with similar deletions. The deletions were inherited in nine out of 12 patients, suggesting variable expressivity and incomplete penetrance. Four patients had tiny deletions involving only EPHA7, suggesting a critical role of EPHA7 in a neurodevelopmental disability phenotype. We provide further evidence for EPHA7 deletion as a risk factor for neurodevelopmental disorder and delineate its clinical phenotype. [ABSTRACT FROM AUTHOR]

Abstract: Purpose Molecular diagnosis based on singleton exome sequencing (sES) is particularly challenging in fetuses with multiple congenital abnormalities (MCA). Indeed, some studies reveal a diagnostic yield of about 20%, far lower than in live birth individuals showing developmental abnormalities (30%), suggesting that standard analyses, based on the correlation between clinical hallmarks described in postnatal syndromic presentations and genotype, may underestimate the impact of the genetic variants identified in fetal analyses. Methods We performed sES in 95 fetuses with MCA. Blind to phenotype, we applied a genotype-first approach consisting of combined analyses based on variants annotation and bioinformatics predictions followed by reverse phenotyping. Initially applied to OMIM-morbid genes, analyses were then extended to all genes. We complemented our approach by using reverse phenotyping, variant segregation analysis, bibliographic search and data sharing in order to establish the clinical significance of the prioritised variants. Results sES rapidly identified causal variant in 24/95 fetuses (25%), variants of unknown significance in OMIM genes in 8/95 fetuses (8%) and six novel candidate genes in 6/95 fetuses (6%). Conclusions This method, based on a genotype-first approach followed by reverse phenotyping, shed light on unexpected fetal phenotype-genotype correlations, emphasising the relevance of prenatal studies to reveal extreme clinical presentations associated with well-known Mendelian disorders.

Abstract: ARHGEF9 defects lead to an X‐linked intellectual disability disorder related to inhibitory synaptic dysfunction. This condition is more frequent in males, with a few affected females reported. Up to now, sequence variants and gross deletions have been identified in males, while only chromosomal aberrations have been reported in affected females who showed a skewed pattern of X‐chromosome inactivation (XCI), suggesting an X‐linked recessive (XLR) disorder. We report three novel loss‐of‐function (LoF) variants in ARHGEF9: A de novo synonymous variant affecting splicing (NM_015185.2: c.1056G>A, p.(Lys352=)) in one female; a nonsense variant in another female (c.865C>T, p.(Arg289*)), that is, also present as a somatically mosaic variant in her father, and a de novo nonsense variant in a boy (c.899G>A; p.(Trp300*)). Both females showed a random XCI. Thus, we suggest that missense variants are responsible for an XLR disorder affecting males and that LoF variants, mainly occurring de novo, may be responsible for an X‐linked dominant disorder affecting males and females.

Abstract: 5‐Amino‐4‐imidazolecarboxamide‐ribosiduria (AICA)‐ribosiduria is an exceedingly rare autosomal recessive condition resulting from the disruption of the bifunctional purine biosynthesis protein PURH (ATIC), which catalyzes the last two steps of de novo purine synthesis. It is characterized biochemically by the accumulation of AICA‐riboside in urine. AICA‐ribosiduria had been reported in only one individual, 15 years ago. In this article, we report three novel cases of AICA‐ribosiduria from two independent families, with two novel pathogenic variants in ATIC. We also provide a clinical update on the first patient. Based on the phenotypic features shared by these four patients, we define AICA‐ribosiduria as the syndromic association of severe‐to‐profound global neurodevelopmental impairment, severe visual impairment due to chorioretinal atrophy, ante‐postnatal growth impairment, and severe scoliosis. Dysmorphic features were observed in all four cases, especially neonatal/infancy coarse facies with upturned nose. Early‐onset epilepsy is frequent and can be pharmacoresistant. Less frequently observed features are aortic coarctation, chronic hepatic cytolysis, minor genital malformations, and nephrocalcinosis. Alteration of the transformylase activity of ATIC might result in a more severe impairment than the alteration of the cyclohydrolase activity. Data from literature points toward a cytotoxic mechanism of the accumulated AICA‐riboside. [ABSTRACT FROM AUTHOR]

Abstract: Purpose Marfanoid habitus (MH) combined with intellectual disability (ID) (MHID) is a clinically and genetically heterogeneous presentation. The combination of array CGH and targeted sequencing of genes responsible for Marfan or Lujan-Fryns syndrome explain no more than 20% of subjects. Methods To further decipher the genetic basis of MHID, we performed exome sequencing on a combination of trio-based (33 subjects) or single probands (31 subjects), of which 61 were sporadic. Results We identified eight genes with de novo variants (DNVs) in at least two unrelated individuals (ARID1B, ATP1A1, DLG4, EHMT1, NFIX, NSD1, NUP205 and ZEB2). Using simulation models, we showed that five genes (DLG4, NFIX, EHMT1, ZEB2 and ATP1A1) met conservative Bonferroni genomewide significance for an excess of the observed de novo point variants. Overall, at least one pathogenic or likely pathogenic variant was identified in 54.7% of subjects (35/64). These variants fell within 27 genes previously associated with Mendelian disorders, including NSD1 and NFIX, which are known to be mutated in overgrowth syndromes. Conclusion We demonstrated that DNVs were enriched in chromatin remodelling (p=2×10-4) and genes regulated by the fragile X mental retardation protein (p=3×10-8), highlighting overlapping genetic mechanisms between MHID and related neurodevelopmental disorders.

39. Novel KIAA1033/WASHC4 mutations in three patients with syndromic intellectual disability and a review of the literature.

Abstract: In 2011, KIAA1033/WASHC4 was associated with autosomal recessive intellectual disability (ARID) in a large consanguineous family comprising seven affected individuals with moderate ID and short stature. Since then, no other cases of KIAA1033 variants have been reported. Here we describe three additional patients (from two unrelated families) with syndromic ID due to compound heterozygous KIAA1033 variants ascertained by exome sequencing (ES). Two sisters, aged 4 and 5.5 years, had a stop‐gain and a missense variants, each inherited from one parent (p.(Gln442*) and p.(Asp1048Gly)). Both had learning disabilities, macrocephaly, dysmorphic features, skeletal anomalies, and subependymal heterotopic nodules. In addition, the younger sibling had a congenital absence of the right internal carotid and bilateral sensorineural hearing loss. The third patient was aged 34 years and had two missense variants, one inherited from each parent (p.(Lys1079Arg) and p.(His503Arg)). This patient presented with mild ID, short stature, and microcephaly. KIAA1033 encodes a large protein (WASHC4), which is part of the WASH complex. The WASH complex is involved in the regulation of the fission of tubules that serve as transport intermediates during endosome sorting. Another member of the WASH complex, KIAA0196/WASHC5, has already been implicated in ARID with brain and cardiac malformations, under the designation of 3C or Ritscher‐Schinzel syndrome (MIM#20210). ES has proved efficient for finding replications of genes with insufficient data in the literature to be defined as new OMIM genes. We conclude that KIAA1033 is responsible for a heterogeneous ARID phenotype, and additional description will be needed to refine the clinical phenotype. [ABSTRACT FROM AUTHOR]

Abstract: Multiple isodicentric Y chromosomes [idic(Y)] is a rare cytogenetic abnormality, most exclusively described in constitutional karyotypes. Only recently has this entity been reported in hematologic neoplasms such as myeloid disorders, albeit these cases remain very scarce. The possible involvement of increasing copies of potential proto-oncogenes located on the multiple idic(Y) led to consider one of them, CRLF2, as a target for kinase inhibitors. We report here, to our knowledge, the first case of multiple idic(Y) in a patient with myelofibrosis secondary to essential thrombocythemia. The patient received ruxolitinib therapy with initial good clinical response. [ABSTRACT FROM AUTHOR]

Abstract: Segmental overgrowth syndromes with cutaneous vascular malformations (Klippel-Trenaunay syndrome (KTS), CLOVES syndrome) are mainly due to mosaic PIK3CA mutations, but the GNAQ , GNA11 , HRAS , KRAS , MAP2K1 , AKT1 , AKT3 , and PIK3R1 genes may also be involved. We sought to determine the frequency and phenotype of patients with PIK3R1 -related segmental overgrowth. Patients were ascertained nationwide in the French MUSTARD cohort of skin mosaic phenotypes. We searched for PIK3R1 mutations by next-generation sequencing on affected tissue in 297 patients with a clinical presentation suggestive of PIK3CA related overgrowth (PROS), but without PIK3CA variants. We retrospectively studied the clinical phenotype of PIK3R1-positive patients. We identified three missense variants and six in-phase indels of PIK3R1 in 15 patients (5.0%), exclusively in affected tissue. Variant allele fraction was 2.0% to 12.0%. We found extensive pale or dark capillary malformations in 14 patients, segmental overgrowth in 11, venous truncal anomalies (varicose veins or persistent lateral marginal vein) in 10, lymphatic malformation in six and a café--au-lait macule or naevus spilus in three, thus defining phacomatosis pigmento-vascularis (PPV). One patient had limb hypoplasia. None had MCAP (Megalencephaly-Capillary malformation). PIKR1 mutations account for a minority of patients with KTS/CLOVES (5%). They are about 20 times less common than PIK3CA mutations. Truncal venous malformations, limb hypoplasia and PPV (spilorosea or melanorosea type) may be more common in PIK3R1-related KTS. No patient had severe or life-threatening involvement. Whether Sirolimus or Alpelisib are treatment options remains to be determined. [ABSTRACT FROM AUTHOR]

Abstract: Objective: Uniparental disomy (UPD) testing is currently recommended during pregnancy in fetuses carrying a balanced Robertsonian translocation (ROB) involving chromosome 14 or 15, both chromosomes containing imprinted genes. The overall risk that such a fetus presents a UPD has been previously estimated to be around ~0.6-0.8%. However, because UPD are rare events and this estimate has been calculated from a number of studies of limited size, we have reevaluated the risk of UPD in fetuses for whom one of the parents was known to carry a nonhomologous ROB (NHROB).Method: We focused our multicentric study on NHROB involving chromosome 14 and/or 15. A total of 1747 UPD testing were performed in fetuses during pregnancy for the presence of UPD(14) and/or UPD(15).Result: All fetuses were negative except one with a UPD(14) associated with a maternally inherited rob(13;14).Conclusion: Considering these data, the risk of UPD following prenatal diagnosis of an inherited ROB involving chromosome 14 and/or 15 could be estimated to be around 0.06%, far less than the previous estimation. Importantly, the risk of miscarriage following an invasive prenatal sampling is higher than the risk of UPD. Therefore, we do not recommend prenatal testing for UPD for these pregnancies and parents should be reassured. [ABSTRACT FROM AUTHOR]

44. Hearing impairment as an early sign of alpha‐mannosidosis in children with a mild phenotype: Report of seven new cases.

Author: Lehalle, Daphné, Colombo, Roberto, O'Grady, Michael, Héron, Bénédicte, Houcinat, Nada, Kuentz, Paul, Moutton, Sebastien, Sorlin, Arthur, Thevenon, Julien, Delanne, Julian, Gay, Sebastien, Racine, Caroline, Garde, Aurore, Tran Mau‐Them, Frédéric, Philippe, Christophe, Vitobello, Antonio, Nambot, Sophie, Huet, Frédéric, Duffourd, Yannis, and Feillet, François
Abstract: Alpha‐mannosidosis (AM) is a very rare (prevalence: 1/500000 births) autosomal recessive lysosomal storage disorder. It is characterized by multi‐systemic involvement associated with progressive intellectual disability, hearing loss, skeletal anomalies, and coarse facial features. The spectrum is wide, from very severe and lethal to a milder phenotype that usually progresses slowly. AM is caused by a deficiency of lysosomal alpha‐mannosidase. A diagnosis can be established by measuring the activity of lysosomal alpha‐mannosidase in leucocytes and screening for abnormal urinary excretion of mannose‐rich oligosaccharides. Genetic confirmation is obtained with the identification of MAN2B1 mutations. Enzyme replacement therapy (LAMZEDER) was approved for use in Europe in August 2018. Here, we describe seven individuals from four families, diagnosed at 3–23 years of age, and who were referred to a clinical geneticist for etiologic exploration of syndromic hearing loss, associated with moderate learning disabilities. Exome sequencing had been used to establish the molecular diagnosis in five cases, including a two‐sibling pair. In the remaining two patients, the diagnosis was obtained with screening of urinary oligosaccharides excretion and the association of deafness and hypotonia. These observations emphasize that the clinical diagnosis of AM can be challenging, and that it is likely an underdiagnosed rare cause of syndromic hearing loss. Exome sequencing can contribute significantly to the early diagnosis of these nonspecific mild phenotypes, with advantages for treatment and management. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: Congenital heart defects (CHDs) may be isolated or associated with other malformations. The use of chromosome microarray (CMA) can increase the genetic diagnostic yield for CHDs by between 4% and 10%. The objective of this study was to evaluate the value of CMA after the prenatal diagnosis of an isolated CHD.Methods: In a retrospective, nationwide study performed in France, we collected data on all cases of isolated CHD that had been explored using CMAs in 2015.Results: A total of 239 fetuses were included and 33 copy number variations (CNVs) were reported; 19 were considered to be pathogenic, six were variants of unknown significance, and eight were benign variants. The anomaly detection rate was 10.4% overall but ranged from 0% to 16.7% as a function of the isolated CHD in question. The known CNVs were 22q11.21 deletions (n = 10), 22q11.21 duplications (n = 2), 8p23 deletions (n = 2), an Alagille syndrome (n = 1), and a Kleefstra syndrome (n = 1).Conclusion: The additional diagnostic yield was clinically significant (3.1%), even when anomalies in the 22q11.21 region were not taken into account. Hence, patients with a suspected isolated CHD and a normal karyotype must be screened for chromosome anomalies other than 22q11.21 duplications and deletions. [ABSTRACT FROM AUTHOR]

47. HCN1 mutation spectrum: from neonatal epileptic encephalopathy to benign generalized epilepsy and beyond.

Subjects: NEUROLOGICAL disorders, CYCLIC nucleotides, HYPERPOLARIZATION (Cytology), EPILEPSY, INTELLECTUAL disabilities
Abstract: Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels control neuronal excitability and their dysfunction has been linked to epileptogenesis but few individuals with neurological disorders related to variants altering HCN channels have been reported so far. In 2014, we described five individuals with epileptic encephalopathy due to de novo HCN1 variants. To delineate HCN1-related disorders and investigate genotype-phenotype correlations further, we assembled a cohort of 33 unpublished patients with novel pathogenic or likely pathogenic variants: 19 probands carrying 14 different de novo mutations and four families with dominantly inherited variants segregating with epilepsy in 14 individuals, but not penetrant in six additional individuals. Sporadic patients had epilepsy with median onset at age 7 months and in 36% the first seizure occurred during a febrile illness. Overall, considering familial and sporadic patients, the predominant phenotypes were mild, including genetic generalized epilepsies and genetic epilepsy with febrile seizures plus (GEFS+) spectrum. About 20% manifested neonatal/infantile onset otherwise unclassified epileptic encephalopathy. The study also included eight patients with variants of unknown significance: one adopted patient had two HCN1 variants, four probands had intellectual disability without seizures, and three individuals had missense variants inherited from an asymptomatic parent. Of the 18 novel pathogenic missense variants identified, 12 were associated with severe phenotypes and clustered within or close to transmembrane domains, while variants segregating with milder phenotypes were located outside transmembrane domains, in the intracellular N- and C-terminal parts of the channel. Five recurrent variants were associated with similar phenotypes. Using whole-cell patch-clamp, we showed that the impact of 12 selected variants ranged from complete loss-of-function to significant shifts in activation kinetics and/or voltage dependence. Functional analysis of three different substitutions altering Gly391 revealed that these variants had different consequences on channel biophysical properties. The Gly391Asp variant, associated with the most severe, neonatal phenotype, also had the most severe impact on channel function. Molecular dynamics simulation on channel structure showed that homotetramers were not conducting ions because the permeation path was blocked by cation(s) strongly complexed to the Asp residue, whereas heterotetramers showed an instantaneous current component possibly linked to deformation of the channel pore. In conclusion, our results considerably expand the clinical spectrum related to HCN1 variants to include common generalized epilepsy phenotypes and further illustrate how HCN1 has a pivotal function in brain development and control of neuronal excitability.

48. STAG1 mutations cause a novel cohesinopathy characterised by unspecific syndromic intellectual disability.

Author: Lehalle, Daphné, Mosca-Boidron, Anne-Laure, Begtrup, Amber, Boute-Benejean, Odile, Charles, Perrine, Cho, Megan T., Clarkson, Amanda, Devinsky, Orrin, Duffourd, Yannis, Duplomb-Jego, Laurence, Gérard, Bénédicte, Jacquette, Aurélia, Kuentz, Paul, Masurel-Paulet, Alice, McDougall, Carey, Moutton, Sébastien, Olivié, Hilde, Soo-Mi Park, Rauch, Anita, and Revencu, Nicole
Abstract: Background Cohesinopathies are rare neurodevelopmental disorders arising from a dysfunction in the cohesin pathway, which enables chromosome segregation and regulates gene transcription. So far, eight genes from this pathway have been reported in human disease. STAG1 belongs to the STAG subunit of the core cohesin complex, along with five other subunits. This work aimed to identify the phenotype ascribed to STAG1 mutations. Methods Among patients referred for intellectual disability (ID) in genetics departments worldwide, arraycomparative genomic hybridisation (CGH), gene panel, whole-exome sequencing or whole-genome sequencing were performed following the local diagnostic standards. Results A mutation in STAG1 was identified in 17 individuals from 16 families, 9 males and 8 females aged 2-33 years. Four individuals harboured a small microdeletion encompassing STAG1; three individuals from two families had an intragenic STAG1 deletion. Six deletions were identified by array-CGH, one by wholeexome sequencing. Whole-exome sequencing found de novo heterozygous missense or frameshift STAG1 variants in eight patients, a panel of genes involved in ID identified a missense and a frameshift variant in two individuals. The 17 patients shared common facial features, with wide mouth and deep-set eyes. Four individuals had mild microcephaly, seven had epilepsy. Conclusions We report an international series of 17 individuals from 16 families presenting with syndromic unspecific ID that could be attributed to a STAG1 deletion or point mutation. This first series reporting the phenotype ascribed to mutation in STAG1 highlights the importance of data sharing in the field of rare disorders. [ABSTRACT FROM AUTHOR]

49. A new family with an SLC9A6 mutation expanding the phenotypic spectrum of Christianson syndrome.

Abstract: Using targeted next generation sequencing, we have identified a splicing mutation (c.526-9_526-5del) in the SLC9A6 gene in a 9-year-old boy with mild intellectual disability (ID), microcephaly, and social interaction disabilities. This intronic microdeletion leads to the skipping of exon 3 and to an in-frame deletion of 26 amino acids in the TM4 domain. It segregates with cognitive impairment or learning difficulties in other members of the family. Mutations in SLC9A6 have been reported in X-linked Christianson syndrome associating severe to profound intellectual deficiency and an Angelman-like phenotype with microcephaly, absent speech, ataxia with progressive cerebellar atrophy, ophthalmoplegia, epilepsy, and neurological regression. The proband and his maternal uncle both have an attenuated phenotype with mild ID, attention deficit disorder, speech difficulties, and mild asymptomatic cerebellar atrophy. The proband also have microcephaly. The mutation cosegregated with learning disabilities and speech difficulties in the female carriers (mother and three sisters of the proband). Detailed neuropsychological, speech, and occupational therapy investigations in the female carriers revealed impaired oral and written language acquisition, with dissociation between verbal and performance IQ. An abnormal phenotype, ranging from learning disability with predominant speech difficulties to mild intellectual deficiency, has been described previously in a large proportion of female carriers. Besides broadening the clinical spectrum of SLC9A6 gene mutations, we present an example of a monogenic origin of mild learning disability. © 2016 Wiley Periodicals, Inc. [ABSTRACT FROM AUTHOR]

50. New Insights into Potocki-Shaffer Syndrome: Report of Two Novel Cases and Literature Review.

Author: Trajkova, Slavica, Di Gregorio, Eleonora, Ferrero, Giovanni Battista, Carli, Diana, Pavinato, Lisa, Delplancq, Geoffroy, Kuentz, Paul, and Brusco, Alfredo
Subjects: AUTHORSHIP in literature, DELETION mutation, DEVELOPMENTAL delay, SYNDROMES, TIBIAL plateau fractures
Abstract: Potocki-Shaffer syndrome (PSS) is a rare non-recurrent contiguous gene deletion syndrome involving chromosome 11p11.2. Current literature implies a minimal region with haploinsufficiency of three genes, ALX4 (parietal foramina), EXT2 (multiple exostoses), and PHF21A (craniofacial anomalies, and intellectual disability). The rest of the PSS phenotype is still not associated with a specific gene. We report a systematic review of the literature and included two novel cases. Because deletions are highly variable in size, we defined three groups of patients considering the PSS-genes involved. We found 23 full PSS cases (ALX4, EXT2, and PHF21A), 14 cases with EXT2-ALX4, and three with PHF21A only. Among the latter, we describe a novel male child showing developmental delay, café-au-lait spots, liner postnatal overgrowth and West-like epileptic encephalopathy. We suggest PSS cases may have epileptic spasms early in life, and PHF21A is likely to be the causative gene. Given their subtle presentation these may be overlooked and if left untreated could lead to a severe type or deterioration in the developmental plateau. If our hypothesis is correct, a timely therapy may ameliorate PSS phenotype and improve patients' outcomes. Our analysis also shows PHF21A is a candidate for the overgrowth phenotype.
