Abstract
Chikungunya is an infectious disease caused by the chikungunya virus (CHIKV), an alphavirus transmitted to humans by Aedes mosquitoes, and for which there is no licensed vaccine nor antiviral treatments. By using a loss-of-function genetic screen, we have recently identified the FHL1 protein as an essential host factor for CHIKV tropism and pathogenesis. FHL1 is highly expressed in muscles cells and fibroblasts, the main CHIKV-target cells. FHL1 interacts with the viral protein nsP3 and plays a critical role in CHIKV genome amplification. Experiments in vivo performed in FHL1-deficient mice have shown that these animals are resistant to infection and do not develop muscular lesions. Altogether these observations, published in the journal Nature [1], show that FHL1 is a key host factor for CHIKV pathogenesis and identify the interaction between FHL1 and nsP3 as a promising target for the development of new antiviral strategies.

Abstract
Hemizygosity of the MIR17HG gene encoding the miR-17 ~ 92 cluster is associated with Feingold syndrome 2 characterized by intellectual disability, skeletal abnormalities, short stature, and microcephaly. Here, we report on a female with a de novo 13q31.3 microduplication encompassing MIR17HG but excluding GPC5. She presented developmental delay, skeletal and digital abnormalities, and features such as tall stature and macrocephaly mirroring those of Feingold syndrome 2 patients. The limited extent of the proband's rearrangement to the miR cluster and the corresponding normal expression level of the neighboring GPC5 in her cells, together with previously described data on affected individuals of two families carrying overlapping duplications of the miR-17 ~ 92 cluster that comprise part of GPC5, who likewise presented macrocephaly, developmental delay, as well as skeletal, digital and stature abnormalities, allow to define a new syndrome due to independent microduplication of the miR-17 ~ 92 cluster.

Abstract
Biallelic pathogenic variants in POMK gene are associated with two types of dystroglycanopathies: limb-girdle muscular dystrophy-dystroglycanopathy, type C12 (MDDGC12), and congenital muscular dystrophy-dystroglycanopathy with brain and eye anomalies, type A12 (MDDGA12). These disorders are very rare and have been previously reported in 10 affected individuals. We present two unrelated Lithuanian families with prenatally detected hydrocephalus due to a homozygous nonsense variant in the POMK. The first signs of hydrocephalus in the affected fetuses became evident at 15 weeks of gestation and rapidly progressed, thus these clinical features are compatible with a diagnosis of MDDGA12. The association between pathogenic POMK variants and macrocephaly and severe hydrocephalus has been previously reported only in two families. Clinical and molecular findings presented in this report highlight congenital hydrocephalus as a distinct feature of POMK related disorders and a differentiator from other dystroglycanopathies. These findings further extend the spectrum of MDDGA12 syndrome.

Abstract
Background Coffin–Siris syndrome is an extremely rare syndrome associated with developmental and congenital anomalies. It is caused by heterozygous pathogenic variants of ARID1A, ARID1B, SMARCA4, SMARCB1, SMARCE1, and SOX11. Methods This case study presents the whole exome sequencing of a patient with characteristic clinical features of Coffin–Siris syndrome. Analysis included Sanger sequencing of complementary DNA and bioinformatic analysis of the variant. Results Analysis of cDNA Sanger sequencing data revealed that the donor splice site variant led to skipping of exon 19. Further, bioinformatic analysis predicted abnormal splicing in a translational frameshift of 11 amino acids and the creation of a premature termination codon. Results found a novel de novo splice site variant c.5025+2T>C in the ARID1B and truncated 1 633 amino acid protein NP_065783.3:p. (Thr1633Valfs*11). Conclusion Truncated ARID1B resulted in loss of the BAF250 domain, which is part of SWI/SNF‐like ATP‐dependent chromatin remodeling complex. The severe clinical manifestation presented by the proband was attributed to the disappearance of the BAF250 domain in the ARID1B protein. Our finding provides strong evidence that this pathogenic variant of exon 19 caused a frameshift mutation in the ARID1B at the terminal exon, resulting in the expression of a severe phenotype of CSS.

Abstract
CHARGE syndrome is an autosomal dominant developmental disorder associated with a constellation of traits involving almost every organ and sensory system, in particular congenital anomalies, including choanal atresia and malformations of the heart, inner ear, and retina. Variants in CHD7 have been shown to cause CHARGE syndrome. Here, we report the identification of a novel de novo p.Asp2119_Pro2120ins6 duplication variant in a conserved region of CHD7 in a severely affected boy presenting with 3 and 5 of the CHARGE cardinal major and minor signs, respectively, combined with congenital umbilical hernia, congenital hernia at the linea alba, mildly hypoplastic inferior vermis, slight dilatation of the lateral ventricles, prominent metopic ridge, and hypoglycemic episodes.

Abstract
Whole-exome and targeted sequencing of 13 individuals from 10 unrelated families with overlapping clinical manifestations identified loss-of-function and missense variants in KIAA1109 allowing delineation of an autosomal-recessive multi-system syndrome, which we suggest to name Alkuraya-Kučinskas syndrome (MIM 617822). Shared phenotypic features representing the cardinal characteristics of this syndrome combine brain atrophy with clubfoot and arthrogryposis. Affected individuals present with cerebral parenchymal underdevelopment, ranging from major cerebral parenchymal thinning with lissencephalic aspect to moderate parenchymal rarefaction, severe to mild ventriculomegaly, cerebellar hypoplasia with brainstem dysgenesis, and cardiac and ophthalmologic anomalies, such as microphthalmia and cataract. Severe loss-of-function cases were incompatible with life, whereas those individuals with milder missense variants presented with severe global developmental delay, syndactyly of 2nd and 3rd toes, and severe muscle hypotonia resulting in incapacity to stand without support. Consistent with a causative role for KIAA1109 loss-of-function/hypomorphic variants in this syndrome, knockdowns of the zebrafish orthologous gene resulted in embryos with hydrocephaly and abnormally curved notochords and overall body shape, whereas published knockouts of the fruit fly and mouse orthologous genes resulted in lethality or severe neurological defects reminiscent of the probands’ features.

Abstract
Myofibrillar myopathies (MFM) are mostly adult-onset diseases characterized by progressive morphological alterations of the muscle fibers beginning in the Z-disk and the presence of protein aggregates in the sarcoplasm. They are mostly caused by mutations in different genes that encode Z-disk proteins, including DES, CRYAB, LDB3, MYOT, FLNC and BAG3. A large family of French origin, presenting an autosomal dominant pattern, characterized by cardiac arrhythmia associated to late-onset muscle weakness, was evaluated to clarify clinical, morphological and genetic diagnosis. Muscle weakness began during adult life (over 30 years of age), and had a proximal distribution. Histology showed clear signs of a myofibrillar myopathy, but with unusual, large inclusions. Subsequently, genetic testing was performed in MFM genes available for screening at the time of clinical/histological diagnosis, and desmin (DES), αB-crystallin (CRYAB), myotilin (MYOT) and ZASP (LDB3), were excluded. LMNA gene screening found the p.R296C variant which did not co-segregate with the disease. Genome wide scan revealed linkage to 7q.32, containing the FLNC gene. FLNC direct sequencing revealed a heterozygous c.3646T>A p.Tyr1216Asn change, co-segregating with the disease, in a highly conserved amino acid of the protein. Normal filamin C levels were detected by Western-blot analysis in patient muscle biopsies and expression of the mutant protein in NIH3T3 showed filamin C aggregates. This is an original FLNC mutation in a MFM family with an atypical clinical and histopathological presentation, given the presence of significantly focal lesions and prominent sarcoplasmic masses in muscle biopsies and the constant heart involvement preceding significantly the onset of the myopathy. Though a rare etiology, FLNC gene should not be excluded in early-onset arrhythmia, even in the absence of myopathy, which occurs later in the disease course.

Abstract
Semaphorins are a large family of secreted and membrane-associated proteins necessary for wiring of the brain. Semaphorin 5A (SEMA5A) acts as a bifunctional guidance cue, exerting both attractive and inhibitory effects on developing axons. Previous studies have suggested that SEMA5A could be a susceptibility gene for autism spectrum disorders (ASDs). We first identified a de novo translocation t(5;22)(p15.3;q11.21) in a patient with ASD and intellectual disability (ID). At the translocation breakpoint on chromosome 5, we observed a 861-kb deletion encompassing the end of the SEMA5A gene. We delineated the breakpoint by NGS and observed that no gene was disrupted on chromosome 22. We then used Sanger sequencing to search for deleterious variants affecting SEMA5A in 142 patients with ASD. We also identified two independent heterozygous variants located in a conserved functional domain of the protein. Both variants were maternally inherited and predicted as deleterious. Our genetic screens identified the first case of a de novo SEMA5A microdeletion in a patient with ASD and ID. Although our study alone cannot formally associate SEMA5A with susceptibility to ASD, it provides additional evidence that Semaphorin dysfunction could lead to ASD and ID. Further studies on Semaphorins are warranted to better understand the role of this family of genes in susceptibility to neurodevelopmental disorders.

Abstract
RNA polymerase III (Pol III) synthesizes tRNAs and other small noncoding RNAs to regulate protein synthesis. Dysregulation of Pol III transcription has been linked to cancer, and germline mutations in genes encoding Pol III subunits or tRNA processing factors cause neurogenetic disorders in humans, such as hypomyelinating leukodystrophies and pontocerebellar hypoplasia. Here we describe an autosomal recessive disorder characterized by cerebellar hypoplasia and intellectual disability, as well as facial dysmorphic features, short stature, microcephaly, and dental anomalies. Whole-exome sequencing revealed biallelic missense alterations of BRF1 in three families. In support of the pathogenic potential of the discovered alleles, suppression or CRISPR-mediated deletion of brf1 in zebrafish embryos recapitulated key neurodevelopmental phenotypes; in vivo complementation showed all four candidate mutations to be pathogenic in an apparent isoform-specific context. BRF1 associates with BDP1 and TBP to form the transcription factor IIIB (TFIIIB), which recruits Pol III to target genes. We show that disease-causing mutations reduce Brf1 occupancy at tRNA target genes in Saccharomyces cerevisiae and impair cell growth. Moreover, BRF1 mutations reduce Pol III-related transcription activity in vitro. Taken together, our data show that BRF1 mutations that reduce protein activity cause neurodevelopmental anomalies, suggesting that BRF1-mediated Pol III transcription is required for normal cerebellar and cognitive development.

Abstract
AIMS The transcription factor Islet-1 (ISL1) is a marker of cardiovascular progenitors and is essential for mammalian cardiogenesis. An ISL1 haplotype has recently been associated with congenital heart disease. In this study we evaluated whether ISL1 variants are associated with hypertrophic (HCM), dilated (DCM), arrhythmogenic right ventricular cardiomyopathy (ARVC), or with Emery-Dreifuss muscular dystrophy (EDMD). METHODS AND RESULTS The six exon and intron boundaries of ISL1 were screened for genetic variants in a cohort of 454 index cases. Eleven exonic variants were identified in HCM, DCM, ARVC, and/or EDMD. Out of the five novel variants, two are located in the 5'-untranslated region, two are silent (p.Arg171Arg and p.Asn189Asn), and one is a missense (p.Asn252Ser). The latter was identified in the homozygous state in one DCM patient, and in the heterozygous state in 11 relatives, who did not present with DCM but often with cardiovascular features. This variant was found in one HCM patient also carrying a MYH7 mutation and in 3/96 North-African Caucasian control individuals, but was absent in 138 European Caucasian control individuals. We investigated the effect of the ISL1 wild type and p.Asn252Ser mutant on myocyte enhancer factor 2C (Mef2c) promoter activity, an established ISL1 target. Mef2c promoter activity was ∼4-fold higher in the presence of wild-type and ∼6-fold higher in the presence of mutant ISL1 in both HEK and CHO cells. CONCLUSION This study describes a new gain-of-function p.Asn252Ser variant in the human ISL1 gene, which could potentially lead to greater activation of downstream targets involved in cardiac development, dilation, and hypertrophy.

Abstract
Shprintzen-Goldberg syndrome (SGS) is characterized by severe marfanoid habitus, intellectual disability, camptodactyly, typical facial dysmorphism, and craniosynostosis. Using family-based exome sequencing, we identified a dominantly inherited heterozygous in-frame deletion in exon 1 of SKI. Direct sequencing of SKI further identified one overlapping heterozygous in-frame deletion and ten heterozygous missense mutations affecting recurrent residues in 18 of the 19 individuals screened for SGS; these individuals included one family affected by somatic mosaicism. All mutations were located in a restricted area of exon 1, within the R-SMAD binding domain of SKI. No mutation was found in a cohort of 11 individuals with other marfanoid-craniosynostosis phenotypes. The interaction between SKI and Smad2/3 and Smad 4 regulates TGF-β signaling, and the pattern of anomalies in Ski-deficient mice corresponds to the clinical manifestations of SGS. These findings define SGS as a member of the family of diseases associated with the TGF-β-signaling pathway.

Abstract
Floating-Harbor syndrome (FHS) is characterized by characteristic facial dysmorphism, short stature with delayed bone age, and expressive language delay. To date, the gene(s) responsible for FHS is (are) unknown and the diagnosis is only made on the basis of the clinical phenotype. The majority of cases appeared to be sporadic but rare cases following autosomal dominant inheritance have been reported. We identified a 4.7 Mb de novo 12q15-q21.1 microdeletion in a patient with FHS and intellectual deficiency. Pangenomic 244K array-CGH performed in a series of 12 patients with FHS failed to identify overlapping deletions. We hypothesized that FHS is caused by haploinsufficiency of one of the 19 genes or predictions located in the deletion found in our index patient. Since none of them appeared to be good candidate gene by their function, a high-throughput sequencing approach of the region of interest was used in eight FHS patients. No pathogenic mutation was found in these patients. This approach failed to identify the gene responsible for FHS, and this can be explained by at least four reasons: (i) our index patient could be a phenocopy of FHS; (ii) the disease may be clinically heterogeneous (since the diagnosis relies exclusively on clinical features), (iii) these could be genetic heterogeneity of the disease, (iv) the patient could carry a mutation in a gene located elsewhere. Recent descriptions of patients with 12q15-q21.1 microdeletions argue in favor of the phenocopy hypothesis.

Abstract
Emery-Dreifuss muscular dystrophy (EDMD) is a rare disorder characterized by early joint contractures, muscular dystrophy, and cardiac involvement with conduction defects and arrhythmias. So far, only 35% of EDMD cases are genetically elucidated and associated with EMD or LMNA gene mutations, suggesting the existence of additional major genes. By whole-genome scan, we identified linkage to the Xq26.3 locus containing the FHL1 gene in three informative families belonging to our EMD- and LMNA-negative cohort. Analysis of the FHL1 gene identified seven mutations, in the distal exons of FHL1 in these families, three additional families, and one isolated case, which differently affect the three FHL1 protein isoforms: two missense mutations affecting highly conserved cysteines, one abolishing the termination codon, and four out-of-frame insertions or deletions. The predominant phenotype was characterized by myopathy with scapulo-peroneal and/or axial distribution, as well as joint contractures, and associated with a peculiar cardiac disease characterized by conduction defects, arrhythmias, and hypertrophic cardiomyopathy in all index cases of the seven families. Heterozygous female carriers were either asymptomatic or had cardiac disease and/or mild myopathy. Interestingly, four of the FHL1-mutated male relatives had isolated cardiac disease, and an overt hypertrophic cardiomyopathy was present in two. Expression and functional studies demonstrated that the FHL1 proteins were severely reduced in all tested patients and that this was associated with a severe delay in myotube formation in the two patients for whom myoblasts were available. In conclusion, FHL1 should be considered as a gene associated with the X-linked EDMD phenotype, as well as with hypertrophic cardiomyopathy.

Abstract
The LMNA gene encodes lamins A and C, components of the nuclear envelope. Its mutations cause a wide range of diseases named laminopathies involving either specific tissues in isolated fashion (cardiac and skeletal muscles, peripheral nerve, adipose tissue) or several tissues in a generalized way (premature ageing syndromes and related disorders). The striated muscle laminopathies include a variety of well clinically characterized disorders where cardiac muscle involvement represents the common feature that coexists with or without skeletal muscle disease. The cardiac disease of LMNA mutated patients is classically defined by conduction system and rhythm disturbances occurring early in the course of the disease, followed by dilated cardiomyopathy and heart failure. These features are life threatening and often responsible of cardiac sudden death. When associated, the skeletal muscle involvement is characterized by muscle weakness and wasting of variable topography with or without early joint contractures and spinal rigidity. Specific management of the cardiac disease to includes antiarrhythmic drugs, cardiac devices such as implantable cardioverter for primary and secondary prevention of sudden death, and heart transplantation at the end stage of heart failure. A large number of LMNA mutations leading to striated muscle laminopathies have been reported without so far any clear and definite phenotype/genotype relation. Finally, among the diverse hypotheses for pathomechanisms of LMNA mutations, the structural hypothesis suggesting a defective role of lamins A/C in maintaining the structural integrity of the nuclear envelope in striated muscles under constant mechanical stress is highly attractive to link the LMNA mutations and the cardiac disease.
