Relevance to Autism
A de novo duplication of the CNTN6 gene was identified in an autistic proband from a simplex family (van Daalen et al., 2011).
Molecular Function
The protein encoded by this gene is a member of the immunoglobulin superfamily. It is a glycosylphosphatidylinositol (GPI)-anchored neuronal membrane protein that functions as a cell adhesion molecule. It may play a role in the formation of axon connections in the developing nervous system.
