DNA/RNA

Description

1123 bp, 8 exons

Protein

Description	280 amino acids and 31 kDa
Expression	widely expressed
Localisation	mitochondrial inner membrane
Function	The complex II (succinate-ubiquinone oxidoreductase) is un key component of the mitochondrial respiratory chain and the tricarboxylic acid cycle. It is involved in the oxidation of succinate (succinate + ubiquinone = fumarate + ubiquinol) and carries electrons from FADH to CoQ. It is composed of four nuclear-encoded subunits. The subunit B protein or iron-sulfur protein, which binds three different iron-sulfur clusters, is directly involved in the catalytic activity of succinate dehydrogenase.
Homology	The complex II includes SDHD (cybS) and SDHC (cybL) which are also implicated in paragangliomas and pheochromocytomas.

Mutations

Germinal

Germline mutations cause hereditary paraganglioma, non-familial paraganglioma, familial and sporadic pheochromocytomas. Different germline mutations have been reported: i) a nonsense mutation (R90X) in a family with cervical paraganglioma and ectopic pheochromocytoma, ii) a missense mutation (P197R) in a family with extraadrenal pheochromocytoma and a 1bp deletion in a sporadic pheochromocytoma, iii) a missense (P131R) mutation and 1 bp insertion (M71fsX80) in familial paraganglioma and a nonsense mutation (Q59X) in sporadic paraganglioma.

Somatic

Loss of wild type allele in tumor DNA is usually observed.

Implicated in

Entity	Hereditary paraganglioma type 4
Note	Alias: Familial non chromaffin paragangliomas 4; Familial glomus tumor; Familial and sporadic pheochromocytoma
Disease	Hereditary paraganglioma type 4 (PGL4) is a rare autosomal dominant disorder non maternally imprinted. Paragangliomas are slow growing highly vascular tumor, usually benigns, derived from crest-neural cells. They are preferentially located in the neck (carotid body and glomus vagal) and head (glomus jugulare and tympanicum). They may be associated with adrenal or extraadrenal pheochromocytomas which produce catecholamines.
Prognosis	It depends on extent of the disease at the time of diagnosis.
