Abstract

Next-generation sequencing has revealed the major impact of de novo variants (DNVs) in developmental disorders (DD) such as intellectual disability, autism, and epilepsy. However, a substantial fraction of these predicted pathogenic DNVs remains challenging to distinguish from background DNVs, notably the missense variants acting via nonhaploinsufficient mechanisms on specific amino acid residues. We hypothesized that the detection of the same missense variation in at least two unrelated individuals presenting with a similar phenotype could be a powerful approach to reveal novel pathogenic variants. We looked for variations independently present in both our database of >1200 solo exomes and in denovo-db, a large, publicly available collection of de novo variants identified in patients with DD. This approach identified 30 variants with strong evidence of pathogenicity, including variants already classified as pathogenic or probably pathogenic by our team, and also several new variants of interest in known OMIM genes or in novel genes. We identified FEM1B and GNAI2 as good candidate genes for syndromic intellectual disability and confirmed the implication of ACTL6B in a neurodevelopmental disorder. Annotation of local variants with denovo-db can highlight missense variants with high potential for pathogenicity, both facilitating the time-consuming reanalysis process and allowing novel DD gene discoveries.

Abstract

International audience; PurposeBased on prenatal suspicion of the combination of radioulnar or radiohumeral synostosis and a peculiar shape of the skull suggestive of craniosynostosis, we report on six patients from four unrelated consanguineous families in whom Antley-Bixler syndrome was suspected during the prenatal period without mutation in genes known to be associated with the syndrome.MethodsMolecular diagnosis involved whole-exome and gene-panel sequencing.Results:All sequenced patients showed a unique homozygous mutation of c.667G>A, p.Gly223Ser (NM_012200) in the beta-1,3-glucuronyltransferase 3 (B3GAT3) gene known to be involved in linkeropathy syndrome. Linkeropathies correspond to a recently identified group of heterogeneous genetic syndromes along a spectrum of skeletal and connective tissue disorders. These patients featured mainly craniosynostosis, midface hypoplasia, bilateral radioulnar synostosis, multiple neonatal fractures, dislocated joints, joint contracture, long fingers, foot deformity, and cardiovascular abnormalities. All died before 1 year of age.ConclusionWe identified a novel B3GAT3-related disorder with craniosynostosis and bone fragility, due to a unique homozygous mutation in B3GAT3. This syndrome should be considered in the prenatal period in light of the severe outcome and as an alternative diagnosis to Antley-Bixler or Shprintzen-Goldberg syndrome.

Abstract

Considering that some Inherited Metabolic Disorders (IMDs) can be diagnosed in patients with no distinctive clinical features of IMDs, we aimed to evaluate the power of exome sequencing (ES) to diagnose IMDs within a cohort of 547 patients with unspecific developmental disorders (DD). IMDs were diagnosed in 12% of individuals with causative diagnosis (177/547). There are clear benefits of using ES in DD to diagnose IMD, particularly in cases where biochemical studies are unavailable. Synopsis Exome sequencing and diagnostic rate of Inherited Metabolic Disorders in individuals with developmental disorders.
