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.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.362T>C (p.M121T) alteration is located in exon 2 (coding exon 2) of the CBR3 gene. This alteration results from a T to C substitution at nucleotide position 362, causing the methionine (M) at amino acid position 121 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
