Mutations of the X-linked genes encoding neuroligins NLGN3 and NLGN4 are associated with autism

Nature Genetics volume 34, pages27–29(2003)Cite this article

Abstract

Many studies have supported a genetic etiology for autism. Here we report mutations in two X-linked genes encoding neuroligins NLGN3 and NLGN4 in siblings with autism-spectrum disorders. These mutations affect cell-adhesion molecules localized at the synapse and suggest that a defect of synaptogenesis may predispose to autism.
