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.
Calibrated functional studies summarized by the ENIGMA BRCA2 specification show that this variant has damaging protein function consistent with pathogenic control variants, and the curated ENIGMA functional table assigns PS3 at Strong strength.
This missense variant lies within the BRCA2 DNA-binding domain, a clinically important functional domain (aa 2481-3186), and the BayesDel no-AF score is 0.575545, which is above the ENIGMA PP3 threshold of 0.30. SpliceAI predicts no splice effect (max delta score 0.00), so the supporting computational evidence is for protein impact rather than splicing.

The BRCA2 c.8168A>C (p.Asp2723Ala; p.D2723A) variant has been reported in ClinVar as pathogenic by the ClinGen ENIGMA BRCA1/2 expert panel and is listed by OncoKB as likely oncogenic.
This variant is present at very low frequency in population databases, with 1/251098 alleles in gnomAD v2.1 and 6/1614162 alleles in gnomAD v4.1, which is too low to support benign frequency criteria but means PM2 is not met because the variant is not absent from controls.
Calibrated BRCA2 functional evidence supports a damaging effect, and the ENIGMA curated functional table assigns PS3 at Strong strength for p.Asp2723Ala.
This missense change occurs within the BRCA2 DNA-binding domain, SpliceAI predicts no splice disruption with a max delta score of 0.00, and the computational profile supports PP3 rather than BP4.
No criteria match.
Apply PS3 when well-established functional studies support a damaging effect; use ENIGMA Table 9 for calibrated BRCA2 assay assignments.
For BRCA2, PP3 applies to missense variants inside a clinically important functional domain with BayesDel no-AF >= 0.30.
PS1 requires the same amino acid change as an established pathogenic/likely pathogenic reference variant.
PM2_Supporting requires absence from gnomAD controls with adequate coverage.
PP4 in BRCA2 uses multifactorial clinical-history LR thresholds.
BA1 requires filter allele frequency above 0.1% in an appropriate non-founder population.
BS1 requires filter allele frequency above ENIGMA benign thresholds.
BS3 requires well-established functional studies showing no damaging effect.
BRCA2 BP1_Strong requires location outside a clinically important functional domain and no predicted splice impact.
For BRCA2 missense variants in a clinically important domain, BP4 requires BayesDel no-AF <= 0.18 and SpliceAI <= 0.1.
BP5 in BRCA2 uses multifactorial clinical-history LR thresholds.
PS4 requires significantly increased prevalence in affected individuals compared with controls under ENIGMA thresholds.
PM3 in BRCA2 is used for qualifying Fanconi anemia cases with co-occurring variants in the same gene.
PP1 requires quantitative co-segregation evidence meeting ENIGMA LR thresholds.
BS2 in BRCA2 is based on a points framework tied to absence of recessive disease features.
BS4 requires quantitative lack-of-segregation evidence meeting ENIGMA LR thresholds.
ENIGMA BRCA2 PVS1 applies to qualifying loss-of-function or RNA-loss variants, not to this missense substitution.
