About BRCA1

No gene-level summary was recorded for this case.

LYFE Sciences is an AI system, and it can make mistakes. Criteria may be applied incorrectly, sources may be misread, and a confident-looking classification can still be wrong. Double-check every criterion and its underlying evidence before relying on any call.
01The reasoning

How it was classified

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.

This missense variant (p.Ser1484Ala) is located at amino acid position 1484, which lies outside all ENIGMA-defined clinically important functional domains (RING aa 2-101, coiled-coil aa 1391-1424, BRCT repeats aa 1650-1857). SpliceAI predicts no splicing impact (max delta score = 0.03, ≤0.1). This meets ENIGMA BP1_Strong per the specification: missense variant outside a clinically important functional domain AND no splicing predicted.

Recorded classification: Likely benign

ENIGMA BRCA1 v1.2.0 point system for conflicting evidence: PM2_Supporting (+1 pathogenic) + BP1_Strong (-4 benign) = -3 total points. Range -6 to -2 = Likely Benign.

NM_007294.4:c.4450T>G (p.Ser1484Ala) is a missense variant in BRCA1 exon 13 located at amino acid position 1484, outside all ENIGMA-defined clinically important functional domains (RING aa 2-101, coiled-coil aa 1391-1424, BRCT repeats aa 1650-1857). SpliceAI predicts no splicing impact (max delta 0.03).

This variant is absent from gnomAD v2.1 and v4.1 population databases, meeting ENIGMA PM2_Supporting.

The variant meets ENIGMA BP1_Strong: missense variant outside a clinically important functional domain with no predicted splicing impact (SpliceAI max delta 0.03 ≤0.1).

This variant is not listed in ENIGMA Table9 (curated functional assays) or ST4 (functional assay results) for either PS3 or BS3. The related variant c.4450T>A (p.Ser1484Thr) has BS3_Strong with 'No functional impact,' but this is a different amino acid substitution and does not constitute direct evidence for p.Ser1484Ala.

No case-control, segregation, or clinical-history likelihood ratio data were identified for this specific variant. It is not listed in the Li et al. 2020 (PMID:31853058) clinical-history LR table; c.4450T>A is listed with neutral LR=1.066.

In ClinVar, this variant is classified as Uncertain Significance by three clinical laboratories (ClinVar ID 630099). No expert panel classification is available.

Under the ENIGMA Table 3 all_of combination rules, one Strong Benign criterion (BP1_Strong) with no qualifying Supporting Benign or Moderate Benign criterion does not meet the Likely Benign threshold (requires Strong Benign + Supporting Benign or Strong Benign + Moderate Benign). The conflicting PM2_Supporting (pathogenic direction) further precludes a benign or likely benign classification. The variant remains a Variant of Uncertain Significance.
