The recorded framework is ClinGen BRCA2 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.
No pathogenic criterion marked as applied in the recorded assessment.
This variant is common in population databases. The gnomAD v2.1 group-maximum filter allele frequency is 0.00162114 and the gnomAD v4.1 group-maximum filter allele frequency is 0.00163682, both above the ENIGMA BA1 threshold of 0.001, so BA1 is met.
This variant exceeds the ENIGMA BS1 threshold for benign population frequency. The gnomAD v2.1 group-maximum filter allele frequency is 0.00162114 and the gnomAD v4.1 group-maximum filter allele frequency is 0.00163682, both above the BS1 strong threshold of 0.0001.
ENIGMA Table 9 assigns BS3 Strong to this variant. Three calibrated studies reported protein function similar to benign control variants, and the listed RNA result showed no aberration, which supports a benign functional interpretation.

The BRCA2 c.8149G>T (p.Ala2717Ser) variant has been observed in somatic cancers in COSMIC (COSV66460731, n=3) and has also been reported in ClinVar, where the ClinGen ENIGMA BRCA1/2 expert panel classifies it as benign.
This variant is common in population databases, with gnomAD v2.1 group-maximum filter allele frequency 0.00162114 and gnomAD v4.1 group-maximum filter allele frequency 0.00163682, both above the ENIGMA BA1 threshold of 0.001.
Calibrated BRCA2 functional evidence supports a benign effect: ENIGMA Table 9 assigns BS3 Strong based on three studies showing function similar to benign controls, with no aberrant RNA result listed.
SpliceAI predicts no significant splice effect for this variant, with a maximum delta score of 0.03, which argues against splice disruption.
