Contactin 4 as an autism susceptibility locus.

ABSTRACT: Structural and sequence variation have been described in several members of the contactin (CNTN) and contactin-associated protein (CNTNAP) gene families in association with neurodevelopmental disorders, including autism. Using array comparative genome hybridization (CGH), we identified a maternally inherited ∼535 kb deletion at 3p26.3 encompassing the 5' end of the contactin 4 gene (CNTN4) in a patient with autism. Based on this finding and previous reports implicating genomic rearrangements of CNTN4 in autism spectrum disorders (ASDs) and 3p- microdeletion syndrome, we undertook sequencing of the coding regions of the gene in a local ASD cohort in comparison with a set of controls. Unique missense variants were identified in 4 of 75 unrelated individuals with ASD, as well as in 1 of 107 c
