Medical Genetics Mitochondrial disease is a chronic genetic disorder that occurs when the mitochondria of the cell fails to produce enough energy for cell or organ function

Medical Genetics Mitochondrial disease is a chronic, genetic disorder that occurs when the mitochondria of the cell fails to produce enough energy for cell or organ function
