Hypertrophic cardiomyopathy with mitochondrial DNA depletion and respiratory enzyme defects.
We report the case of a child with severe hypertrophic cardiomyopathy, with decreased activity levels of cardiac mitochondrial respiratory complex I and III, and with a pronounced reduction in cardiac mitochondrial DNA copy number level. Mitochondrial DNA depletion has not been previously reported in hypertrophic cardiomyopathy and it may play a role in its pathogenesis.
