Genes affected

AKR1A1 (HGNC:380): (aldo-keto reductase family 1 member A1) This gene encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. This member, also known as aldehyde reductase, is involved in the reduction of biogenic and xenobiotic aldehydes and is present in virtually every tissue. Multiple alternatively spliced transcript variants of this gene exist, all encoding the same protein. [provided by RefSeq, Jan 2011]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.214C>T (p.R72W) alteration is located in exon 5 (coding exon 3) of the AKR1A1 gene. This alteration results from a C to T substitution at nucleotide position 214, causing the arginine (R) at amino acid position 72 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
