Notes This database is one of the TCA cycle gene variant databases (formerly SDH Complex databases)
CITATION: if you benefit from the use of this database and publish findings, please cite; Bayley JP, Devilee P, Taschner PE (2005). BMC Med Genet. 6:39.
SDHA is associated with paragangliomas and pheochromocytomas. SDHA has at least one pseudogene, which is located on chromosome 3p29 (Parfait et al., 2000). The pseudogene(s) may interfere with sequence variation detection. The variants included in the database were derived from the published literature or submitted directly and, where necessary, annotated to conform to current HGVS mutation nomenclature. When you notice any omissions or mistakes, please let us know (thank you).
Disclaimer: inclusion of sequence variants in the SDH mutation database does not imply that there is convincing evidence for pathogenicity.
