Scientists Link Gene Mutation to Autism Risk
Teams of scientists working independently have for the first time identified several gene mutations that they agree sharply increase the chances that a child will develop. They have found further evidence that the risk increases with the age of the parents, particularly in fathers over age 35.
The gene mutations are extremely rare and together account for a tiny fraction of autism cases — in these studies, only a handful of children. Experts said the new research gave scientists something they had not had: a clear strategy for building some understanding of the disease’s biological basis.
