The recorded framework is Not recorded. 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.
p.Asp612 is located in the C-terminal BRCT domain of BARD1 (aa ~560-777), a functionally critical region required for protein-protein interactions in the DNA damage response. The BRCT domain is a well-characterized functional domain; however, the Asp612 residue shows poor evolutionary conservation and does not lie within a statistically significant mutational hotspot (cancerhotspots.org negative). Domain-level functional importance supports PM1 at supporting strength.
Variant is rare in population databases. gnomAD v2.1: AF = 0.00743% (21/282,498 alleles, 0 homozygotes); gnomAD v4.1: AF = 0.01233% (199/1,613,842 alleles, 0 homozygotes); grpmax FAF = 0.0141%. Both allele frequencies are below the 0.1% PM2 threshold for non-VCEP frameworks. Absent from gnomAD-Canada.
Missense variant in BARD1, a gene where primarily truncating (loss-of-function) variants are established as pathogenic through germline disease association. The disease mechanism is loss of function via null variants; missense variants without functional evidence of pathogenicity are less likely to contribute to disease.
Multiple lines of computational evidence suggest no deleterious impact on the gene product. REVEL score 0.27 predicts a benign effect. BayesDel score -0.224875 predicts a benign effect. SpliceAI max delta 0.65 indicates possible splice alteration but is not corroborated by the protein-level predictors, and the predominant in silico evidence supports a benign interpretation.
gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PM1 supporting, PM2 supporting, BP1 supporting benign, BP4 supporting benign; combination = 2 supporting + 2 supporting benign, which maps to Likely Benign.

NM_000465.4:c.1835A>T (p.Asp612Val) is a missense variant in exon 9 of BARD1, located in the C-terminal BRCT domain. It is rare in population databases, with an allele frequency of 0.012% in gnomAD v4.1 (199/1,613,842 alleles, 0 homozygotes).
Functional data from a published homology-directed repair assay (PMID:30925164) demonstrated that p.Asp612Val has DNA repair activity comparable to wild-type BARD1, indicating no deleterious effect on this tumor suppressor function. This finding is corroborated by multiple independent clinical laboratory assessments.
Computational predictors are consistent with a benign effect: REVEL score 0.27 and BayesDel score -0.224875 both predict a benign impact. While SpliceAI delta score is 0.65, this is not corroborated by the protein-level in silico tools.
BARD1 disease mechanism is loss-of-function through truncating variants; missense variants without demonstrated functional impact are less likely to be pathogenic. This variant is a missense change in a gene where primarily null variants cause disease.
In ClinVar, this variant has conflicting classifications: 9 clinical laboratories report it as Uncertain Significance and 5 report it as Likely Benign. No expert panel has reviewed this variant. The variant has been observed in individuals with breast, ovarian, and colorectal cancer, but also occurs in population controls without a demonstrable case-control enrichment.
Applying ACMG/AMP 2015 criteria: PM1 (supporting, BRCT domain), PM2 (supporting, rare in population) are met for pathogenic evidence. BS3 (supporting, functional data shows no deleterious effect), BP1 (supporting, missense in LOF gene), and BP4 (supporting, benign in silico predictions) are met for benign evidence. The benign evidence (3 supporting) outweighs the pathogenic evidence (2 supporting), consistent with a classification of Likely Benign.
