A new batch of studies offers strong evidence that genetics plays a role in autism, the BBC reports. The studies in the journal Nature show that most victims have a variation in their DNA in the area that controls how brain cells interact, notes the LA Times. The results raise the hope for better diagnosis and treatment, researchers say.
"It is very exciting," said the study leader. "It opens up the opportunity someday for new interventions to fix the bad consequences this variant has on brain function and development."
