Medical Conditions

A disease that results from a congenital defect in CYTOCHROME-C OXIDASE. Defects in cytochrome-c oxidase can be caused by mutations in the SURF1, SCO2, COX10, or SCO1 genes. Cytochrome-c oxidase deficiency caused by mutation in SURF1 manifests itself as LEIGH DISEASE; that caused by mutation in SCO2 as fatal infantile cardioencephalomyopathy; that caused by mutation in COX10 as tubulopathy and leukodystrophy; and that caused by mutation in SCO1 as early-onset hepatic failure and neurologic disorder.
