KEGG   DISEASE: Mitochondrial respiratory chain deficiencies (MRCD)Help
H00473                      Disease                                

Mitochondrial respiratory chain deficiencies (MRCD), including:
Mitochondrial complex I deficiency (MT-C1D);
Complex II deficiency (MT-C2D);
Complex III deficiency (MT-C3D);
Leigh syndrome (LS) [DS:H01354];
Leber Hereditary Optic Neuropathy (LHON) [DS:H00068];
Leber Optic Atrophy and Dystonia (LDYT) [DS:H01365];
MELAS Syndrome [DS:H01347];
Kearns-Sayre Syndrome (KSS) [DS:H01355];
GRACILE Syndrome
Mitochondrial respiratory chain deficiencies (MRCD) are a group of disorders of adults and children, with highly variable phenotypes that include macrocephaly with progressive leukodystrophy, encephalopathy (including MELAS), cardiomyopathy, myopathy, liver disease, Leigh syndrome, Leber hereditary optic neuropathy, and some forms of Parkinson disease and Alzheimer's disease.
