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.
SpliceAI predicts a strong splice effect for this synonymous variant, with a maximum delta score of 0.89, which is above the BRCA2 ENIGMA PP3 threshold of 0.20 for predicted splicing impact. This supports PP3 at supporting strength.
Clinical-history likelihood-ratio analysis for BRCA2 c.9117G>A showed LR 3.91 in 12 probands, which is above the ENIGMA PP4 supporting threshold of 2.08 and below the moderate threshold of 4.3. This supports PP4 at supporting strength.

The BRCA2 c.9117G>A (p.(Pro3039=), p.(P3039=)) variant has been reported in ClinVar as pathogenic, including an expert-panel pathogenic classification from the ClinGen ENIGMA BRCA1/2 Variant Curation Expert Panel.
This variant is rare in population databases but is not absent from controls, with 1/248378 alleles in gnomAD v2.1 (AF 0.00000403) and 6/1613032 alleles in gnomAD v4.1 (AF 0.00000372), so PM2 is not met and BA1/BS1 thresholds are not reached.
Clinical-history likelihood-ratio analysis for BRCA2 c.9117G>A showed LR 3.91 in 12 probands, which exceeds the ENIGMA PP4 supporting threshold of 2.08 and supports PP4 at supporting strength.
SpliceAI predicts a strong splice effect for this synonymous variant, with a maximum delta score of 0.89, which is above the ENIGMA PP3 threshold of 0.20 for predicted splicing impact and argues against BP4/BP7.
No criteria match.
ENIGMA BRCA1/2 PP3 applies for silent, missense/in-frame, and relevant intronic variants when SpliceAI is at least 0.20.
ENIGMA BRCA1/2 PP4 uses multifactorial clinical data with PP4 supporting at LR ≥2.08, moderate at ≥4.3, and strong at ≥18.7.
ENIGMA BRCA1/2 VCEP PVS1 requires a null variant or mRNA-only functional evidence showing a damaging transcript effect at the appropriate strength.
ENIGMA BRCA1/2 PM2 is supporting only when the variant is absent from controls.
ENIGMA BRCA1/2 BA1 requires FAF greater than 0.001.
ENIGMA BRCA1/2 BS1 applies when FAF is above 0.00002 (supporting) or above 0.0001 (strong).
ENIGMA BRCA1/2 BP1_Strong requires location outside key functional domains and SpliceAI at or below 0.10.
ENIGMA BRCA1/2 BP4 for silent variants requires SpliceAI ≤0.10.
ENIGMA BRCA1/2 BP5 applies only when the multifactorial clinical LR is at or below 0.48.
ENIGMA BRCA1/2 BP7 for silent variants inside a key domain requires BP4, unless RNA studies directly support a benign transcript effect.
ENIGMA BRCA1/2 PS1 may be used for the same protein change or the same demonstrated splice impact as a previously classified pathogenic or likely pathogenic variant.
Apply PS3 only when well-established functional studies for the exact variant support a damaging effect.
ENIGMA BRCA1/2 PS4 requires a significant enrichment in affected individuals compared with controls.
ENIGMA BRCA1/2 PM3 is reserved for BRCA2-related Fanconi anemia contexts with point-based trans observations.
ENIGMA BRCA1/2 PP1 requires quantitative segregation evidence reaching the specified likelihood-ratio thresholds.
ENIGMA BRCA1/2 BS2 is a Fanconi-anemia-context rule with point-based thresholds.
Apply BS3 only when well-established functional studies for the exact variant support no damaging effect.
ENIGMA BRCA1/2 BS4 requires quantitative evidence for lack of segregation reaching the specified likelihood-ratio thresholds.
