A Joint Study from USC and Vanderbilt says "We Need To Learn Where Toxins Impact Gene Expression to Find the Cause of Autism."

A new study written up in Science Daily (Mar. 2, 2009) and elsewhere says that researchers at the University of Southern California (USC) and Vanderbilt University have “identified a specific gene variant that links increased genetic risk for autism with gastrointestinal (GI) conditions.”

So far, reporting on the study, to be published in Pediatrics, has suggested that a polymorphism in the Met gene has been identified which, by itself, may explain both brain abnormalities and GI disturbances in children with autism spectrum disorder.

Kirby quotes the study, “We need to learn where toxins impact gene expression in order to find the cause of autism. Finally, if we are going to understand functional etiology of ASD, if we are trying to identify the genes that underlie risk, and we are searching for environmental factors that cause changes in brain development, we need to know where these candidate genes are expressed in the developing human brain, and where these environmental factors have their impact.”
