The recorded framework is ClinGen BRCA1 VCEP v1.2.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
In calibrated functional studies summarized by the BRCA1 expert-panel specification, this variant showed abnormal protein function consistent with loss of function. Table 9 assigns PS3_Strong for c.5089T>C, and the supplementary functional dataset records complete functional impact/LOF.
This variant is absent from gnomAD v2.1 and absent from gnomAD v4.1. That absence supports rarity in population controls and is consistent with PM2_Supporting.
This missense variant lies within the BRCA1 BRCT repeats, a clinically important functional domain, and computational evidence supports a damaging protein effect. BayesDel is 0.398132, which is above the BRCA1 PP3 threshold of 0.28, REVEL is 0.914, and SpliceAI does not predict a meaningful splice effect (max delta score 0.08). These findings support PP3.

The BRCA1 c.5089T>C (p.Cys1697Arg) variant has not been observed in COSMIC and has been reported in ClinVar, including a pathogenic expert-panel classification from ClinGen ENIGMA.
This variant is absent from gnomAD v2.1 and gnomAD v4.1, supporting rarity in population controls.
In calibrated functional studies summarized by the BRCA1 expert-panel resources, this variant showed loss of BRCA1 function, and the expert-panel table assigns PS3_Strong.
Computational evidence supports a damaging protein effect because the variant is in the BRCA1 BRCT repeats, BayesDel is 0.398132 (above the PP3 threshold of 0.28), and REVEL is 0.914, while SpliceAI predicts no significant splice effect with a max delta score of 0.08.
