The BRCA2 c.794-2A>G (p.?) variant has been reported in ClinVar, where the ClinGen ENIGMA BRCA1 and BRCA2 Variant Curation Expert Panel classifies it as uncertain significance, while other submitters have reported likely pathogenic or pathogenic interpretations.
This variant is absent from gnomAD v2.1 and present once in gnomAD v4.1 at an overall allele frequency of 6.260650932398744e-07 (1/1597278 alleles; 0 homozygotes), indicating that it is very rare in population databases.
In the ENIGMA BRCA2 exon-level splice/PVS1 table, this exact splice acceptor variant is associated with observed in-frame exon 10 skipping and assigned PVS1_N/A (RNA), so current VCEP evidence does not support treating it as a qualifying loss-of-function event under PVS1.
SpliceAI predicts strong splice impact for this variant with a maximum delta score of 0.99 (DS_AL 0.99, DS_AG 0.31), but the BRCA2 ENIGMA framework does not apply PP3 to canonical ±1,2 splice-site variants and this splice prediction should not be double-counted against the variant-specific RNA/PVS1 assessment.
No criteria match.
ENIGMA PS1 for splice variants requires the same predicted or demonstrated splicing impact as a previously classified pathogenic or likely pathogenic variant.
ENIGMA PS3 requires well-established damaging functional studies; mRNA-only splice evidence is handled through the RNA/PVS1 framework.
ENIGMA PM2_Supporting requires absence from controls in qualifying gnomAD datasets; a single outbred observation is not informative.
ENIGMA BA1 requires filter allele frequency greater than 0.1% (0.001).
ENIGMA BS1 requires filter allele frequency above 0.00002 for supporting or above 0.0001 for strong evidence.
ENIGMA BS3 requires well-established studies showing no damaging effect.
ENIGMA PS4 requires a significant increase in prevalence among affected individuals versus controls.
ENIGMA PM3 applies only in the recessive Fanconi anemia context with point-based case evidence.
ENIGMA PP1 requires quantitative co-segregation evidence.
ENIGMA PP4 requires a calibrated multifactorial likelihood ratio of at least 2.08 toward pathogenicity.
ENIGMA BS2 requires point-based evidence from individuals lacking the relevant recessive phenotype.
ENIGMA BS4 requires quantitative evidence for lack of segregation.
ENIGMA BP5 requires a calibrated multifactorial likelihood ratio of 0.48 or less against pathogenicity.
