Genes affected

CBR3 (HGNC:1549): (carbonyl reductase 3) Carbonyl reductase 3 catalyzes the reduction of a large number of biologically and pharmacologically active carbonyl compounds to their corresponding alcohols. The enzyme is classified as a monomeric NADPH-dependent oxidoreductase. CBR3 contains three exons spanning 11.2 kilobases and is closely linked to another carbonyl reductase gene - CBR1.

Ambry Genetics

Nov 02, 2023

The c.631C>T (p.R211C) alteration is located in exon 3 (coding exon 3) of the CBR3 gene. This alteration results from a C to T substitution at nucleotide position 631, causing the arginine (R) at amino acid position 211 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
