Big news about autism this morning. Researchers have found strong evidence of a genetic risk factor for autism.
A study of more than 10,000 children at the Children's Hospital of Philadelphia found a common genetic variation that increases the risk a child will develop autism.
The variation is located in an area that regulates neurological development, learning and memory. The researchers also identified another genetic change that in rare cases also appears to contribute to autism.
An estimated 1 in 150 children have some form of Autism Spectrum Disorder. Most of those affected are boys.
