More evidence mutation behind autism

January 10, 2008 12:00:00 AM PST
The cause of autism still remains a mystery to scientists, but a new finding shows they may be closer to finding out.Most evidence suggests autism is largely caused by some genetic mutation. Now scientists from Massachusetts General Hospital say they've found a rare genetic abnormality on one chromosome that is a hundred times more common among people with autism.

The gene involved has to do with language, which might explain why some children with autism have speech delay.

Still, doctors say more genes are involved, and that's where research will continue.
