Autism and Schizophrenia: Family History May Not Always Be a Good Indicator

Pin It

An international study led by University of Montreal scientists suggests family history may not be a good predictor of the presence of mutations predisposing to autism or schizophrenia.

The findings show how new or de novo gene mutations — alterations of the cell’s DNA — play a role in these devastating conditions. Published in the American Journal of Human Genetics, this study has implications for disease prevalence and severity.
