Medical Researchers May Have Found Gene Linked To Autism

Researchers think they may have another clue to understanding autism and treating it.

They've found that a rare genetic variation dramatically raises the risk of developing autism. Researchers have been focusing on genetic causes of autism, because so many families have multiple children with it.

Researchers who conducted this latest large study estimate that the gene glitch they've identified will account for another 1 percent of cases.

They're now focusing on a chromosome that has genes that are linked to brain development and various developmental disorders. The researchers found that a segment of the chromosome was either missing or duplicated far more often in autistic people.
