About BRCA2

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 BRCA2 VCEP v1.2. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.

BP5Supporting
BP5 · supporting

ENIGMA BP5 Supporting applies when the combined likelihood ratio from multifactorial likelihood clinical data is ≤ 0.48:1. The combined LR from Parsons et al. 2019 (PMID:31131967) multifactorial analysis for NM_000059.4:c.8386C>T is 0.123, with a posterior probability of pathogenicity of 0.0038 and IARC class 2 (Likely Benign). The combined LR of 0.123 supports BP5 at Supporting strength. The combined LR incorporates co-occurrence, family history, pathology, and case-control likelihood components.

Recorded classification: Uncertain significance

ENIGMA BRCA2 v1.2 Table 3 combination rules applied. Only BP5 met at Supporting benign strength (Parsons et al. 2019 combined LR=0.123). No Likely Benign combination rule matches: all Likely Benign rules require either 2x Supporting (Benign) or 1x Strong (Benign) + 1x Supporting/Moderate (Benign). No pathogenic criteria met. ENIGMA point system yields -1 point, which maps to Uncertain Significance range (-1 to 5). Variant defaults to VUS.

Statements for reports

The evidence statements recorded by the interpretation pipeline. They have not been reinterpreted by the page.

gnomAD v4.1

This variant is present in gnomAD v4.1 (AF= 1.73486e-05; MAF= 0.00173%, 28/1613960 alleles, homozygotes = 0) and has highest observed frequency in the African/African American population (AF= 5.33163e-05; MAF= 0.00533%, 4/75024 alleles, homozygotes = 0); grpmax FAF= 1.744e-05.

gnomAD v2.1

This variant is present in gnomAD v2.1 (AF= 1.59082e-05; MAF= 0.00159%, 4/251442 alleles, homozygotes = 0) and has highest observed frequency in the European (non-Finnish) population (AF= 3.51716e-05; MAF= 0.00352%, 4/113728 alleles, homozygotes = 0); grpmax FAF= 1.122e-05.

gnomAD-Canada

Absent from gnomAD-Canada v1.0.

ClinVar

This variant has been reported in ClinVar as Uncertain significance (7 clinical laboratories) and as Likely benign (4 clinical laboratories) and as Benign (1 clinical laboratory). (ClinVarID = 91511)

In silico

SpliceAI predicts no significant splice impact for this variant (max delta score = 0.16). REVEL score = 0.328. BayesDel score = -0.202329.

Functional

OncoKB did not identify variant-specific reviewed functional evidence for this variant; gene-level curated context is available for reviewer follow-up. BRCA2, a tumor suppressor involved in the DNA damage response, is mutated in various cancer types.

Somatic

This variant does not lie in a statistically significant hotspot. This variant has not previously been reported in somatic cancers (COSMIC).

Cancer Hotspots
