Genes affected

CBR1 (HGNC:1548): (carbonyl reductase 1) The protein encoded by this gene belongs to the short-chain dehydrogenases/reductases (SDR) family, which function as NADPH-dependent oxidoreductases having wide specificity for carbonyl compounds, such as quinones, prostaglandins, and various xenobiotics. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Nov 2013]

CBR1 links:

SETD4 (HGNC:1258): (SET domain containing 4) Enables histone methyltransferase activity (H4-K20 specific). Involved in histone H4-K20 trimethylation. Located in cytosol and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.285C>A (p.F95L) alteration is located in exon 1 (coding exon 1) of the CBR1 gene. This alteration results from a C to A substitution at nucleotide position 285, causing the phenylalanine (F) at amino acid position 95 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
