Genes affected

AKR1D1 (HGNC:388): (aldo-keto reductase family 1 member D1) The enzyme encoded by this gene is responsible for the catalysis of the 5-beta-reduction of bile acid intermediates and steroid hormones carrying a delta(4)-3-one structure. Deficiency of this enzyme may contribute to hepatic dysfunction. Three transcript variants encoding different isoforms have been found for this gene. Other variants may be present, but their full-length natures have not been determined yet. [provided by RefSeq, Jul 2010]

Loss-of-function variants in AKR1D1 are known to be pathogenic (PMID: 12970144, 19175828, 20522910, 21185810, 23679950). This variant has been reported in an individual affected with neonatal liver failure (PMID: 19175828). This gene is also known as SRD5B1 in the literature. This variant is present in population databases (rs749224036, ExAC 0.009%). This sequence change creates a premature translational stop signal (p.Arg50*) in the AKR1D1 gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. -
