Autism Genes Linked to Higher Intelligence

Genetic variations associated with autism spectrum disorders (ASDs) have been linked to better cognitive ability in individuals who do not have the condition, new research suggests.

A large population-based study showed that individuals in the general population who carry more of the genetic variations associated with ASD perform slightly better on cognitive function tests than those who carry fewer of the genetic variants, although the advantage conferred by ASD-associated genes appears to be small.

“Links between autism and better cognitive function have been suspected and are widely implied by the well-known Silicon Valley syndrome and films such as Rain Man,” coinvestigator Nick Martin, PhD, Queensland Institute for Medical Research, Brisbane, Australia, said in a statement.

“This study suggests genes for autism may actually confer, on average, a small intellectual advantage in those who carry them, provided they are not affected by autism.“
