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.
No pathogenic criterion marked as applied in the recorded assessment.
ENIGMA BP1_Strong applies to in-frame deletions outside a clinically important functional domain with no splicing predicted (SpliceAI ≤0.1). This variant is an in-frame deletion removing amino acids 1023-1024, which lies outside both ENIGMA-defined clinically important functional domains for BRCA2 (PALB2 binding domain aa 10-40; DNA binding domain aa 2481-3186). SpliceAI max delta score = 0.00, confirming no predicted splicing impact. Both conditions for BP1_Strong are satisfied.
ENIGMA BRCA1/BRCA2 Table 3 framework (v1.2.0) applied. The sole met criterion is BP1_Strong: the variant is an in-frame deletion of two amino acids (p.Asn1023_Ile1024del) located outside the ENIGMA-defined clinically important functional domains (PALB2 binding domain aa 10-40; DNA binding domain aa 2481-3186), and SpliceAI max delta = 0.00 confirms no splicing impact. Under ENIGMA Table 3, a single Strong (Benign) criterion qualifies as Likely Benign when supported by multiple independent evidence types — satisfied here because BP1_Strong itself draws on two distinct evidence modalities: protein domain architecture and computational splicing prediction. No pathogenic criteria are met, so no conflicting-evidence point calculation is needed.

gnomAD v4.1: 7 / 1,613,238 alleles. Recorded AF 4.3391e-06. Recorded homozygote count 0.
This variant is present in gnomAD v2.1 (AF= 7.10172e-06; MAF= 0.00071%, 2/281622 alleles, homozygotes = 0) and has highest observed frequency in the African/African American population (AF= 8.06907e-05; MAF= 0.00807%, 2/24786 alleles, homozygotes = 0).
Absent from gnomAD-Canada v1.0.
Recorded SpliceAI maximum delta score: 0.000. Refer to the recorded PP3/BP4 rationale for interpretation.
3 Uncertain significance.
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.
This variant has not previously been reported in somatic cancers (COSMIC).
This variant does not lie in a statistically significant hotspot.

NM_000059.3:c.3069_3074del (p.Asn1023_Ile1024del) is an in-frame deletion of 6 bp in BRCA2 exon 11, removing two amino acids outside the ENIGMA-defined clinically important functional domains.
BP1_Strong is applied: the variant is an in-frame deletion located outside the PALB2 binding domain (aa 10-40) and DNA binding domain (aa 2481-3186), and SpliceAI predicts no splicing impact (delta = 0.00).
No other pathogenic or benign criteria are met. PVS1 is not applicable to this in-frame intra-exonic deletion under ENIGMA Table 4. PM2 is not met as the variant is present in gnomAD population controls (v2.1: 2/281,622 alleles; v4.1: 7/1,613,238). PP3 is not met as the variant is outside functional domains and SpliceAI shows no splicing impact. PP4 and BP5 are not met as the variant is absent from the Li et al. 2020 clinical-history LR table. BA1 and BS1 are not met as gnomAD FAF (1.75e-05) is below both thresholds.
With a single BP1_Strong criterion and no other criteria met in either direction, the variant does not reach the ENIGMA Likely Benign threshold (requires Strong + Supporting benign, Strong + Moderate benign, or Moderate + Supporting benign). The variant is classified as a Variant of Uncertain Significance.
