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.
No pathogenic criterion marked as applied in the recorded assessment.
ENIGMA BS1_Strong applies when FAF exceeds 0.01% (FAF > 0.0001). gnomAD v2.1 grpmax FAF is 0.00024454 (0.024%); the variant is observed in 12/282,222 total alleles (AF=4.25e-05) with highest subpopulation frequency in the African/African American population (11/24,934 alleles, AF=0.044%). This exceeds the ENIGMA BS1_Strong threshold of >0.01%.
ENIGMA Table 9 (v1.2.0) explicitly assigns BS3_Strong for NM_007294.3:c.1233T>G (p.Asp411Glu). One calibrated functional study (Bouwman et al. 2020, PMID:32546644) demonstrates that this variant exhibits protein function similar to benign control variants in homologous recombination repair complementation assays, meeting the criteria for well-established functional evidence of no damaging effect.
ENIGMA BP1_Strong applies to missense variants located outside all (potentially) clinically important functional domains with no predicted splicing impact (SpliceAI ≤0.1). Codon 411 is outside the three defined domains: RING (aa 2-101), coiled-coil (aa 1391-1424), and BRCT (aa 1650-1857). SpliceAI max delta score is 0.07 (≤0.1). Both conditions for BP1_Strong are satisfied.

NM_007294.3:c.1233T>G (p.Asp411Glu) is a missense variant in BRCA1 exon 10, classified as Benign by the ClinGen ENIGMA BRCA1 and BRCA2 Variant Curation Expert Panel (ClinVar Variation ID: 41804).
This variant is present in gnomAD v2.1 at 12/282,222 alleles (AF=4.25e-05) with a grpmax filter allele frequency of 0.024% (0.00024454) in the African/African American subpopulation (11/24,934 alleles), exceeding the ENIGMA BS1_Strong threshold of >0.01%.
ENIGMA Table 9 (v1.2.0) assigns BS3_Strong to this variant based on calibrated functional assay evidence from Bouwman et al. 2020 (PMID:32546644), demonstrating protein function in homologous recombination repair complementation similar to benign control variants.
Codon 411 is located outside all three (potentially) clinically important functional domains defined by ENIGMA for BRCA1: RING finger (aa 2-101), coiled-coil (aa 1391-1424), and BRCT repeats (aa 1650-1857). SpliceAI predicts no splicing impact (max delta score 0.07). These findings satisfy ENIGMA BP1_Strong criteria.
Parsons et al. 2019 multifactorial likelihood analysis (PMID:31131967) reports a combined LR of 1.29, a segregation LR of 1.93, and a family history LR of 6.48 for this variant. The combined LR is in the neutral range and does not independently support either pathogenic (PP4) or benign (BP5) classification.
No evidence was found to support any pathogenic criterion. PVS1, PS1, PS2, PS3, PS4, PS5, PM1, PM2, PM5, PM6, PP1, PP2, PP3, PP4, and PP5 are all either not met or not applicable.
Under the ENIGMA Table 3 combination rules, two or more Strong Benign criteria support a Benign classification. The three Strong Benign criteria met (BS1_Strong, BS3_Strong, BP1_Strong) satisfy the Benign classification threshold.
