New candidate gene may explain male bias of autism

by  /  24 March 2011

A gene that regulates the conversion of testosterone to estrogen in the brain could help explain why males are more susceptible to autism than are females, according to a study published in PLoS One in February.

IQ scores not a good measure of function in autism

by  /  6 January 2011

Most studies define high-functioning children as those with an IQ above 70 or 80, but this is problematic for a number of reasons, say some scientists. The assumption underlying the use of high IQ as a synonym for high functioning is suspect because social and communicative abilities may have a far greater impact on an individual’s daily interactions.

Study finds weak genetic link between autism and intelligence

by  /  20 July 2010

Autism and intellectual disability often occur together, but in most cases that overlap is not genetic, according to a study of twin pairs published in the American Journal of Medical Genetics. Unraveling this link might help researchers pinpoint brain circuits involved in both conditions, and better understand the diversity of symptoms in the autism spectrum, experts say.

Random genetic changes may explain variability in autism

by  /  13 April 2010

Random changes in gene expression can cause genetically identical embryos to develop different traits, according to a study of worms published in Nature. The findings suggest that haphazard movements of molecules could partly explain why autism-associated mutations don’t always cause the same symptoms.

Face recognition is distinct genetic skill, studies find

by  /  11 March 2010

The ability to recognize faces and interpret facial expressions is programmed partly by genes and inherited separately from other traits, according to three independent studies published this year.
