Maternally-inherited diabetes with deafness (MIDD) and hyporeninemic hypoaldosteronism

Diabetes mitocondrial (MIDD) e hipoaldosteronismo hiporreninêmico

Maternally-inherited diabetes with deafness (MIDD) is a rare form of monogenic diabetes that results, in most cases, from an A-to-G transition at position 3243 of mitochondrial DNA (m.3243A>G) in the mitochondrial-encoded tRNA leucine (UUA/G) gene. As the name suggests, this condition is characterized by maternally-inherited diabetes and bilateral neurosensory hearing impairment. A characteristic of mitochondrial cytopathies is the progressive multisystemic involvement with the development of more symptoms during the course of the disease. We report here the case of a patient with MIDD who developed hyporeninemic hypoaldosteronism. Arq Bras Endocrinol Metab. 2012;56(8):574-7
