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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.547G>A (p.V183M) alteration is located in exon 3 (coding exon 3) of the CBR3 gene. This alteration results from a G to A substitution at nucleotide position 547, causing the valine (V) at amino acid position 183 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
