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.
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.
