Study narrows down genetic suspects in autism

Researchers have narrowed down the list of genes implicated in autism spectrum disorder, and they appear to point toward a part of the brain that has largely been overlooked.

Most research into the genetic roots of autism, a highly heritable disorder that affects about 1 in 68 children, starts with a kind of inventory of genes. Then, it narrows down this genome-wide survey to prime suspects that appear to be different among those with one or several of the symptoms of autism.

That gene-by-gene approach, however, has unearthed too many suspects, each with somewhat vague relationships to a small sliver of the autism spectrum. That situation has sparked some to abandon the gene-by-gene approach in favor of environmental factors that may alter gene behavior.
