ROULEAU, Auteur Article en page(s) : 102055 Langues : Anglais (eng) Mots-clés : CNTN5 CNV intronic deletions neurodevelopment inherited Index. décimale : PER Périodiques Résumé : Background Contactin-5 (CNTN5) is a candidate risk gene for autism spectrum disorder (ASD). Previous attempts to associate CNTN5 CNVs with ASD-susceptibility were limited by insufficient statistical power. Here, we aim to clarify the putative association between CNTN5 CNVs and ASD-risk using large-scale case-control analyses. Method A CNTN5 CNV, shared by four brothers in a multiplex family with ASD, was initially identified. We calculated the prevalence and transmission of CNTN5 CNVs in cases across five ASD cohorts (n=15,784). Second, we compared the prevalence of CNTN5 CNVs in cases to their unaffected siblings (n=4,996). Third, we assessed the enrichment of CNTN5 CNVs in cases to extrafamilial controls across three cohorts (n=24,886) and the UK Biobank (n = 459,862). Finally, we evaluated the clinical impact of CNTN5 CNVs in a broad neurodevelopmental disorder cohort and the DECIPHER database. Results Most (96.7%) CNTN5 CNV deletions (0.193%) and duplications (0.03%) in cases were inherited by a parent that transmitted the variant to their affected and unaffected children at the same rate. We identified a significant enrichment of intronic CNTN5 CNV deletions in cases compared to extrafamilial controls (0.178% versus 0.019%; p-value=1.68E-05; OR:8.51; 95%CI=[2.58-44.21]). There was no difference in CNTN5 CNV enrichment between cases and individuals with NDDs. Conclusions Intronic CNTN5 CNV deletions are rare, inherited, and intermediate effect size ASD-susceptibility variants that may also confer risk for other neuropsychiatric disorders. We offer a framework to characterize candidate variants that may not be detected through small-scale approaches to implicate intermediate effect size variants in the etiology of ASD.

Titre : Genetic Causes of Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Guillaume HUGUET, Auteur ; Thomas BOURGERON, Auteur Année de publication : 2016 Importance : p.13-24 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders CNV Heritability SNV Synapse Twin studies Index. décimale : SCI-D SCI-D - Neurosciences Résumé : In the past 30 years, twin studies have indicated a strong genetic contribution to autism spectrum disorders (ASD). The heritability of ASD is estimated to be 50%. Whereas most of the inherited part of ASD is captured by common variants, our knowledge about the genetics of ASD comes almost exclusively from identification of highly penetrant de novo mutations through candidate gene or whole exome/genome sequencing studies. Approximately 10% of patients with ASD, especially those with intellectual disability, are carriers of de novo copy number or single nucleotide variants affecting clinically relevant genes for ASD. Because of the function of these genes, it was hypothesized that abnormal synaptic plasticity and failure of neuronal/synaptic homeostasis could increase the risk of ASD. It is hoped that this knowledge will lead to better diagnosis, care, and integration of individuals with ASD.
