Autism Changes Gene Expression in the Brain, Scientists Say

There are well-defined genetic patterns within the brains of all autism patients, no matter their symptoms, according to scientists who say the finding may help identify a cause and a new way to attack the disease.

The patterns are seen in the way genes are expressed to create proteins in the brain, according to a paper published in the journal Nature. Distinct similarities were found among autistic brains in areas that play a role in judgment, creativity, emotions and speech, the report said. Brains of those without the disease showed different patterns.
