Autism Genes Can add Up to Genius

from the Times (London)

Some people with autism have amazed experts with their outstanding memories, mathematical skills or musical talent. Now scientists have found that the genes thought to cause autism may also confer mathematical, musical and other skills on people without the condition.

The finding has emerged from a study of autism among 378 Cambridge University students, which found the condition was up to seven times more common among mathematicians than students in other disciplines. It was also five times more common in the siblings of mathematicians.

If confirmed, it could explain why autism-a disability that makes it hard to communicate with, and relate to, others-continues to exist in all types of society. It suggests the genes responsible are usually beneficial, causing the disease only if present in the wrong combinations.
