General annotation (Comments)

Function	Membrane-anchoring subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q) By similarity.
Pathway	Carbohydrate metabolism; tricarboxylic acid cycle.
Subunit structure	Component of complex II composed of four subunits: the flavoprotein (FP) SDHA, iron-sulfur protein (IP) SDHB, and a cytochrome b560 composed of SDHC and SDHD.
Subcellular location	Mitochondrion inner membrane; Multi-pass membrane protein.
Involvement in disease	Paragangliomas 1 (PGL1) [MIM:168000]: A neural crest tumor usually derived from the chromoreceptor tissue of a paraganglion. PGL1 is a rare autosomal dominant disorder which is characterized by the development of mostly benign, highly vascular, slowly growing tumors in the head and neck. In the head and neck region, the carotid body is the largest of all paraganglia and is also the most common site of the tumors. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.11 Ref.12 Ref.13 Ref.14 Ref.20 Pheochromocytoma (PCC) [MIM:171300]: A catecholamine-producing tumor of chromaffin tissue of the adrenal medulla or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of epinephrine and norepinephrine, is hypertension, which may be persistent or intermittent. Note: Disease susceptibility is associated with variations affecting the gene represented in this entry. Intestinal carcinoid tumor (ICT) [MIM:114900]: A yellow, well-differentiated, circumscribed tumor that arises from enterochromaffin cells in the small intestine or, less frequently, in other parts of the gastrointestinal tract. Note: Disease susceptibility is associated with variations affecting the gene represented in this entry. Paraganglioma and gastric stromal sarcoma (PGGSS) [MIM:606864]: Gastrointestinal stromal tumors may be sporadic or inherited in an autosomal dominant manner, alone or as a component of a syndrome associated with other tumors, such as in the context of neurofibromatosis type 1 (NF1). Patients have both gastrointestinal stromal tumors and paragangliomas. Susceptibility to the tumors was inherited in an apparently autosomal dominant manner, with incomplete penetrance. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.23 Cowden syndrome 3 (CWS3) [MIM:615106]: A form of Cowden syndrome, a hamartomatous polyposis syndrome with age-related penetrance. Cowden syndrome is characterized by hamartomatous lesions affecting derivatives of ectodermal, mesodermal and endodermal layers, macrocephaly, facial trichilemmomas (benign tumors of the hair follicle infundibulum), acral keratoses, papillomatous papules, and elevated risk for development of several types of malignancy, particularly breast carcinoma in women and thyroid carcinoma in both men and women. Colon cancer and renal cell carcinoma have also been reported. Hamartomas can be found in virtually every organ, but most commonly in the skin, gastrointestinal tract, breast and thyroid. Note: The disease may be caused by mutations affecting the gene represented in this entry. Ref.24
Sequence similarities	Belongs to the CybS family.
