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.

CBR3-AS1 (HGNC:43664): (CBR3 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2024The c.256G>A (p.V86I) alteration is located in exon 1 (coding exon 1) of the CBR3 gene. This alteration results from a G to A substitution at nucleotide position 256, causing the valine (V) at amino acid position 86 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
