Environment or genetics in autism symptomatology? How about both?

This week I am in Minneapolis at an incredibly important meeting of Medical Examiners to pitch them the importance of collecting brain tissue for Autism BrainNet.  While I was here I noticed a new study on the blogs that is important for families to hear about.  It focused on a known environmental exposure in established genetic groups.  The authors of the study, led by Dr. Sara Webb at University of Washington, showed that an environmental exposure can modify symptoms in genetically susceptible narrow subgroups.  This is the sort of research that will better describe how environmental exposures are affecting autism risk.   Thank you to Dr. Sara Webb for your perspectives and interpretation of the data!
