title: Cytochrome c oxidase deficiency and long-chain acyl coenzyme A dehydrogenase deficiency with Leigh's subacute necrotizing encephalomyelopathy.
abstract: A female infant was seen at the age of 2 months because of hypotonia, delayed motor development, and lactic acidosis, and she died at age 13 months due to respiratory failure. In a muscle specimen taken at 11 months and in a liver specimen obtained 1.5 hours postmortem, we found decreased activities of cytochrome c oxidase and long-chain acyl coenzyme A dehydrogenase. Neuropathological changes were typical for Leigh's subacute necrotizing encephalomyelopathy. To our knowledge, this is the first report of a combined defect of complex IV of the respiratory chain and of the long-chain specific acyl coenzyme A dehydrogenase of beta-oxidation in muscle and liver.
