Novel copy number variants in children with autism and additional developmental anomalies / L. K. DAVIS in Journal of Neurodevelopmental Disorders, 1-4 (December 2009)
[article]
Titre : Novel copy number variants in children with autism and additional developmental anomalies Type de document : Texte imprimé et/ou numérique Auteurs : L. K. DAVIS, Auteur ; K. J. MEYER, Auteur ; D. S. RUDD, Auteur ; A. L. LIBRANT, Auteur ; E. A. EPPING, Auteur ; V. C. SHEFFIELD, Auteur ; T. H. WASSINK, Auteur Article en page(s) : p.292-301 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Autism is a neurodevelopmental disorder characterized by three core symptom domains: ritualistic-repetitive behaviors, impaired social interaction, and impaired communication and language development. Recent studies have highlighted etiologically relevant recurrent copy number changes in autism, such as 16p11.2 deletions and duplications, as well as a significant role for unique, novel variants. We used Affymetrix 250K GeneChip Microarray technology (either NspI or StyI) to detect microdeletions and duplications in a subset of children from the Autism Genetic Resource Exchange (AGRE). In order to enrich our sample for potentially pathogenic CNVs we selected children with autism who had additional features suggestive of chromosomal loss associated with developmental disturbance (positive criteria filter) but who had normal cytogenetic testing (negative criteria filter). We identified families with the following features: at least one child with autism who also had facial dysmorphology, limb or digit abnormalities, or ocular abnormalities. To detect changes in copy number we used a publicly available program, Copy Number Analyser for GeneChip(R) (CNAG) Ver. 2.0. We identified novel deletions and duplications on chromosomes 1q24.2, 3p26.2, 4q34.2, and 6q24.3. Several of these deletions and duplications include new and interesting candidate genes for autism such as syntaxin binding protein 5 (STXBP5 also known as tomosyn) and leucine rich repeat neuronal 1 (LRRN1 also known as NLRR1). Lastly, our data suggest that rare and potentially pathogenic microdeletions and duplications may have a substantially higher prevalence in children with autism and additional developmental anomalies than in children with autism alone.
