Genes affected

AKR1C2 (HGNC:385): (aldo-keto reductase family 1 member C2) This gene encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. These enzymes catalyze the conversion of aldehydes and ketones to their corresponding alcohols using NADH and/or NADPH as cofactors. The enzymes display overlapping but distinct substrate specificity. This enzyme binds bile acid with high affinity, and shows minimal 3-alpha-hydroxysteroid dehydrogenase activity. This gene shares high sequence identity with three other gene members and is clustered with those three genes at chromosome 10p15-p14. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

The c.764T>G (p.I255S) alteration is located in exon 9 (coding exon 7) of the AKR1C2 gene. This alteration results from a T to G substitution at nucleotide position 764, causing the isoleucine (I) at amino acid position 255 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
