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.
This variant is too common for a pathogenic BRCA2 variant under the ENIGMA frequency framework. In gnomAD v2.1, the grpmax filter allele frequency is 0.00155833, which is above the BA1 threshold of 0.001 in a non-founder population.
This variant exceeds the BRCA2 BS1 frequency threshold. In gnomAD v2.1, the grpmax filter allele frequency is 0.00155833, which is above the BS1 strong threshold of 0.0001.
This intronic variant is outside the native donor and acceptor +/-1,2 splice sites, and SpliceAI predicts no significant splice effect with a maximum delta score of 0.04, which is below the BRCA2 BP4 threshold of 0.1. This supports BP4.

The BRCA2 c.68-7del (p.?) variant has been reported in ClinVar and is classified as Benign by the ClinGen ENIGMA BRCA1 and BRCA2 expert panel, although some ClinVar submissions remain uncertain significance.
This variant is present in gnomAD, and in gnomAD v2.1 the grpmax filter allele frequency is 0.00155833, which is above the ENIGMA BRCA2 BA1 threshold of 0.001 and the BS1 strong threshold of 0.0001.
Computational splicing evidence does not support a deleterious effect because SpliceAI predicts a maximum delta score of 0.04, which is below the BRCA2 BP4 threshold of 0.1 and below the PP3 threshold of 0.2.
No criteria match.
Apply BA1 when non-founder population FAF is >0.1%.
Apply BS1_Strong when non-founder population FAF is >0.01%.
Apply BP4_Supporting for noncanonical intronic variants with no predicted splice impact.
ENIGMA BRCA2 PVS1 applies to null variants or qualifying RNA evidence; this variant does not currently meet those conditions.
PM2_Supporting requires absence from controls and is not applied to indels in this specification.
PP3 for noncanonical intronic variants requires predicted splicing impact meeting the VCEP threshold.
Splicing-based PS1 requires a qualifying previously classified comparator with the same predicted splice event.
PS3 requires well-established functional evidence supportive of a damaging effect.
PS4 requires significant enrichment in affected individuals compared with controls.
PM3 in this VCEP is reserved for BRCA2-related Fanconi anemia contexts with point-based scoring.
PP1 requires quantitative cosegregation evidence meeting ENIGMA likelihood-ratio thresholds.
PP4 in this VCEP uses calibrated multifactorial clinical data with LR >=2.08 for supporting evidence.
BS2 in this VCEP requires scored observations in the absence of recessive disease features.
BS3 requires well-established functional evidence supportive of no damaging effect.
BS4 requires quantitative nonsegregation evidence meeting ENIGMA likelihood-ratio thresholds.
BP5 in this VCEP uses calibrated multifactorial clinical data with LR <=0.48 for supporting benign evidence.
