Gene Linked to Severity of Autism’s Social Dysfunction Identified

Published April 7, 2011 in Science Daily

With the help of two sets of brothers with autism, Johns Hopkins scientists have identified a gene associated with autism that appears to be linked very specifically to the severity of social interaction deficits. The gene, GRIP1 (glutamate receptor interacting protein 1), is a blueprint for a traffic-directing protein at synapses — those specialized contact points between brain cells across which chemical signals flow.
