Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_001757.4(CBR1):c.260T>A(p.Leu87Gln) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,457,950 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L87R) has been classified as Uncertain significance.

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]
