A patient with Fuch's corneal, dystrophy, sensorineural hearing loss, diabetes, cardiac conduction defects, ataxia, and hyperreflexia is described.Analysis of lymphocyte mitochondrial DNA showed missense mutations usually associated with Leber's hereditary optic neuropathy. The occurrence of Fuch's dystrophy in this patient and the biology of corneal endothelial cells suggest that mitochondrial defects could be the cause of Fuch's endothelial dystrophy.
