Analysis finds differences in gene activity

Though autism and related disorders vary widely from person to person, certain brain changes may be at the root of the disorder.

Changes in genes important for brain-cell development and function contribute to the poorly understood disorder, a study published online May 25 in Nature shows. Finding genetic contributors to the multifaceted disease might help scientists design better ways to treat it.

“For us to be able to develop specific therapies that treat the cause, you have to understan...
