DNA Scan Uncovers 18 Genes Newly Associated With Autism

The finding adds to evidence that autism is a condition caused by genetics

A new genetic analysis has uncovered 18 genes associated with autism, NBC News reported.

The study observed people with autism and their relatives, and found that people with autism often had dozens of mutations that could have caused their symptoms. There was an average of 73 unique mutations, according to the team at Autism Speaks.

The study adds to evidence that autism is a condition caused by genetics, and that each person with autism has his or her own pattern of DNA changes. The 18 genes that were identified have not been previously linked with autism, however, they are all involved in brain cell communications.
