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. [provided by RefSeq, Jul 2008]
CBR3-AS1 (HGNC:43664): (CBR3 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.541A>C (p.N181H) alteration is located in exon 3 (coding exon 3) of the CBR3 gene. This alteration results from a A to C substitution at nucleotide position 541, causing the asparagine (N) at amino acid position 181 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
