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

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.

The gnomAD v2.1 exome grpmax filter allele frequency (FAF) is 0.000106 (0.0106%), which exceeds the ENIGMA BS1 Strong threshold of FAF > 0.01% (FAF > 0.0001) in non-cancer, non-founder populations. This is observed primarily in the East Asian subpopulation (6/19,916 alleles, AF = 0.030%).

This is an in-frame deletion (p.Leu1740_Ser1741del) located outside the two ENIGMA-defined clinically important functional domains (PALB2 binding aa 10–40; DNA binding aa 2481–3186). SpliceAI predicts no splicing impact (max delta = 0.00, ≤ 0.1). ENIGMA BP1_Strong criteria are satisfied: in-frame deletion outside a clinically important domain with no splicing predicted.

Recorded classification: Benign

ENIGMA BRCA2 Table 3 combining rules applied to adjudicated criteria. Two Strong Benign criteria are met: BS1_Strong (gnomAD grpmax FAF = 0.0106% exceeds ENIGMA BS1 Strong threshold of >0.01%) and BP1_Strong (in-frame deletion p.Leu1740_Ser1741del outside clinically important functional domains with SpliceAI max delta = 0.00, no splicing impact). The ENIGMA Table 3 benign rule 'Strong (Benign) >= 2' is satisfied. No pathogenic criteria are met, so there is no conflicting evidence to adjudicate.

NM_000059.3:c.5218_5223del (p.Leu1740_Ser1741del) is an in-frame deletion of 6 nucleotides in BRCA2 exon 11, removing two amino acids (Leu1740 and Ser1741) from a region between BRC repeats 5 and 6, outside the ENIGMA-defined clinically important functional domains.

The variant is present in gnomAD population databases at a grpmax filter allele frequency of 0.0106% (FAF = 0.000106) in gnomAD v2.1 exomes, exceeding the ENIGMA BS1 Strong threshold of > 0.01% (FAF > 0.0001). Highest subpopulation frequency is in East Asians (AF = 0.030%, 6/19,916 alleles). No homozygotes observed.

As an in-frame deletion located outside the ENIGMA-defined clinically important functional domains (PALB2 binding aa 10–40; DNA binding aa 2481–3186) with no splicing impact predicted (SpliceAI max delta = 0.00), ENIGMA BP1_Strong is met: in-frame deletion outside a clinically important domain without splicing prediction.

Clinical-history likelihood ratio from Li et al. 2020 (PMID:31853058) is 0.77 (8 probands), falling in the neutral zone. Neither PP4 nor BP5 is applicable.

This variant has been reported in ClinVar as Uncertain significance by 9 clinical laboratories and Likely benign by 1 clinical laboratory (ClinVar Variation ID: 51824; review status: criteria provided, single submitter). No expert panel classification exists.

No functional studies, case-control data, segregation data, or variant-specific publications were identified for this variant. Five publications were reviewed in full text; none mention NM_000059.3:c.5218_5223del.

Applying the ENIGMA Table 3 combining rules: two Strong Benign criteria (BS1 + BP1) satisfy the Benign classification threshold (Strong Benign ≥ 2). This variant is classified as BENIGN.
