(HealthDay)—The largest study of its kind, involving more than 2 million people across five countries, finds that autism spectrum disorders are 80% reliant on inherited genes. That means that environmental causes are responsible for just 20% of the risk. The findings could open new doors to research into the genetic causes of autism, which the U.S. Centers for Disease Control […]

The preliminary study, presented Thursday at the American Heart Association’s Vascular Discovery Scientific Sessions, sought to identify sex-specific markers of plaque instability […]
