Genomic variations and chromosomal abnormalities

Autism spectrum disorder (ASD) has a strong but complex genetic component. Here we report on the resequencing of 64 candidate neurodevelopmental disorder risk genes in 5,979 individuals: 3,486 probands and 2,493 unaffected siblings. We find a strong burden of de novo point mutations for these genes and specifically implicate nine genes. These include CHD2 and SYNGAP1, genes previously reported in related disorders, and novel genes TRIP12 and PAX5. We also show that mutation carriers generally have lower IQs and enrichment for seizures. These data begin to distinguish genetically distinct subtypes of autism important for aetiological classification and future therapeutics. Autism spectrum disorder (ASD) is a common disorder with a strong and complex genetic component. Here, the authors resequence 64 candidate neurodevelopmental disorder risk genes in almost 6,000 samples and identify novel genes associated with ASD.
