New model for autism suggests women carry the disorder and explains age as a risk factor

...s more likely in men, making women the more likely carriers of new mutations. The fact that germ-line mutations increase with age places older parents at a higher risk of having children with autism, explaining a pattern that has been recently observed, said CSHL co-author of the study Michael Wigler, Ph.D. ...
