Genes affected
AKR1B1 (HGNC:381): (aldo-keto reductase family 1 member B) This gene encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. This member catalyzes the reduction of a number of aldehydes, including the aldehyde form of glucose, and is thereby implicated in the development of diabetic complications by catalyzing the reduction of glucose to sorbitol. Multiple pseudogenes have been identified for this gene. The nomenclature system used by the HUGO Gene Nomenclature Committee to define human aldo-keto reductase family members is known to differ from that used by the Mouse Genome Informatics database.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.787A>G (p.K263E) alteration is located in exon 8 (coding exon 8) of the AKR1B1 gene. This alteration results from a A to G substitution at nucleotide position 787, causing the lysine (K) at amino acid position 263 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
