Mutations in the mitochondrial genome can cause mitochondrial diabetes. We present two cases in which the same mutation, mtDNA3243A>G, caused two different
phenotypes: maternally inherited diabetes and deafness and mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes. Mitochondrial disease can imitate a
variety of common conditions and should be considered in the case of multisystem disease, complex neurological symptoms or neurological symptoms combined with
symptoms of other organ systems.
