Diseases due mtDNA mutations are commonly referred to as “mitochondrial encephalomyopathies” because they preferentially affect tissues with high metabolic requirements such as brain and skeletal muscle. Clinical presentations are heterogeneous: diabetes mellitus, hearing loss, cardiomyopathy, or encephalomyopathy. This heterogeneity is particularly true for mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes syndrome (MELAS) associated with the A3243G mutation.1,2
