Multiple recurrent de novo copy number variations (CNVs), including duplications of the 7q11.23 Williams-Beuren syndrome region, are strongly associated with autism
Given prior evidence for the contribution of rare copy number variations (CNVs) to autism spectrum disorders (ASD), we studied these events in 4,457 individuals from 1,174 simplex families, composed of parents, a proband and, in most kindreds, an unaffected sibling. We find significant association o...

Summary: | Given prior evidence for the contribution of rare copy number variations (CNVs) to autism spectrum disorders (ASD), we studied these events in 4,457 individuals from 1,174 simplex families, composed of parents, a proband and, in most kindreds, an unaffected sibling. We find significant association of ASD with
de novo
duplications of 7q11.23, where the reciprocal deletion causes Williams-Beuren syndrome, featuring a highly social personality. We identify rare recurrent
de novo
CNVs at five additional regions including two novel ASD loci, 16p13.2 (including the genes
USP7
and
C16orf72
) and
Cadherin13
, and implement a rigorous new approach to evaluating the statistical significance of these observations. Overall, we find large
de novo
CNVs carry substantial risk (OR=3.55; CI =2.16-7.46, p=6.9 × 10
−6
); estimate the presence of 130-234 distinct ASD-related CNV intervals across the genome; and, based on data from multiple studies, present compelling evidence for the association of rare
de novo
events at 7q11.23, 15q11.2-13.1, 16p11.2, and
Neurexin1. |
