Genes affected

HADH (HGNC:4799): (hydroxyacyl-CoA dehydrogenase) This gene is a member of the 3-hydroxyacyl-CoA dehydrogenase gene family. The encoded protein functions in the mitochondrial matrix to catalyze the oxidation of straight-chain 3-hydroxyacyl-CoAs as part of the beta-oxidation pathway. Its enzymatic activity is highest with medium-chain-length fatty acids. Mutations in this gene cause one form of familial hyperinsulinemic hypoglycemia. The human genome contains a related pseudogene of this gene on chromosome 15. [provided by RefSeq, May 2010]

Potent mutations in HADH gene are associated with congenital hyperinsulinism, which leads to recurrent hypoglycemia. The condition is exacerbated by stress, fasting or excessive dietary protein. May respond well to diazoxide. However, the role of this particular variant rs552317372 in congenital hyperinsulinism is yet to be ascertained. -
