Mutations Not Inherited from Parents Cause More Than Half the Cases of Schizophrenia

Columbia University Medical Center researchers have shown that new, or “de novo,” protein-altering mutations — genetic errors that are present in patients but not in their parents — play a role in more than 50 percent of “sporadic” — i.e., not hereditary — cases of schizophrenia.

The findings will be published online on August 7, 2011, in Nature Genetics….
