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 GeneticsDec 17, 2023The c.50T>C (p.I17T) alteration is located in exon 1 (coding exon 1) of the CBR3 gene. This alteration results from a T to C substitution at nucleotide position 50, causing the isoleucine (I) at amino acid position 17 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
