On autism's cause, researchers just 'scratching the surface'
Two studies strongly suggest some people have a genetic predisposition to autism, the NIH says. "Identical twin studies show that if one twin is affected, there is a 90 percent chance the other twin will be affected."
Not necessarily to the same degree, it sounds.
Dr. Eric Hollander, who was director of the Seaver and New York Autism Center of Excellence in 2008, told CNN.com at the time that "of all neuropsychiatric disorders, there's a stronger genetic predisposition for autism. It's also clear that early environmental experiences can play an important role in modifying how these genes develop."
And there's your answer, Anonymoose. :-)
