Mitochondrial DNA variants in schizophrenia: association studies

Abstract

The frequency of three selected mitochondrial DNA variations was compared between cases with schizophrenia and two groups of unrelated controls: screened adults and neonates. The comparisons were conducted separately among Caucasians and African-Americans. No significant differences were detected, suggesting that the variants may not be associated with schizophrenia. Limitations of the study are discussed.
