Classification rationale
1
The BARD1 c.2127A>G (p.Pro709=) variant has not been observed in somatic cancers in COSMIC and has been reported in ClinVar with Likely benign and Benign submissions.

This variant is absent from gnomAD v2.1 and gnomAD v4.1, with an observed allele frequency of 0, which is below the benign frequency thresholds and does not by itself support pathogenicity for a synonymous variant.
gnomad_v2 ↗ gnomad_v4 ↗3
In silico analysis predicts no meaningful splice effect, with a SpliceAI maximum delta score of 0.00, and the variant is synonymous at p.Pro709=, supporting BP7 and not supporting PP3.
