RGD uses the Human Disease Ontology (DO, for disease curation across species. RGD automatically downloads each new release of the ontology on a monthly basis. Some additional terms which are required for RGD's curation purposes but are not currently covered in the official version of DO have been added. As corresponding terms are added to DO, these custom terms are retired and the DO terms substituted in existing annotations and subsequently used for curation.

Definition:A mitochondrial metabolism disease characerized by a highly variable phenotype. Some patients have multisystem involvement of the brain, heart, muscle, liver, and kidneys resulting in death in infancy, whereas others have only isolated cardiac or muscle involvement with onset in adulthood and normal cognition. It has_material_basis_in homozygous or compound heterozygous mutation in the nuclear-encoded SDHA gene on chromosome 5p, the nuclear-encoded SDHAF1 gene on chromosome 19q, or the nuclear-encoded SDHD gene on chromosome 11q23. (DO)
Synonyms:exact_synonym: isolated mitochondrial respiratory chain complex II deficiency;   isolated succinate-CoQ reductase deficiency;   isolated succinate-coenzyme Q reductase deficiency;   isolated succinate-ubiquinone reductase deficiency;   succinate CoQ reductase deficiency
 primary_id: MESH:C565375
 alt_id: OMIM:252011
 xref: GARD:5053;   ORDO:3208
