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.
This variant is present at extremely low frequency in population databases. gnomAD v2.1: 17/280,222 alleles (AF = 0.00607%); gnomAD v4.1: 196/1,611,434 alleles (AF = 0.01216%). Both are well below the 0.1% threshold for PM2 supporting. No homozygotes observed. Highest subpopulation frequency is European (non-Finnish): 0.0125% (v2.1) and 0.0155% (v4.1).
Multiple lines of computational evidence support a benign interpretation. REVEL score is 0.053 (strongly predicts benign), BayesDel score is -0.567 (predicts benign), and SpliceAI max delta is 0.11 (no predicted splicing impact). All available in silico tools agree on a lack of deleterious effect.
gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PM2 supporting, BP4 supporting; combination = 1 supporting + 1 supporting benign, which maps to VUS.

NM_000465.4:c.568G>A (p.Asp190Asn) is a missense variant in exon 4 of BARD1.
This variant is present at extremely low frequency in population databases: gnomAD v2.1 AF = 0.00607% (17/280,222 alleles) and gnomAD v4.1 AF = 0.01216% (196/1,611,434 alleles), meeting PM2 at supporting strength.
Multiple lines of computational evidence support a benign interpretation: REVEL score 0.053, BayesDel score -0.567, and SpliceAI max delta 0.11, meeting BP4 at supporting strength.
No variant-specific functional data exist. Adamovich et al. 2019 (PMID:30925164) tested 76 BARD1 missense variants in an HDR assay but did not include p.Asp190Asn. All 22 variants in the linker region between the RING and ankyrin domains were found to be HDR-functional.
This variant has been reported in ClinVar as Uncertain significance (12 clinical laboratories) and Likely benign (5 clinical laboratories), with review status 'criteria provided, single submitter' (1-star). No expert panel has evaluated this variant.
PVS1 is not applicable as this is a missense variant. PS1-PS5, PM1, PM5-PM6, PP1-PP5, BA1, BS1-BS4, BP1-BP2, BP5-BP6 are not met. BP7 is not applicable.
The net evidence balance is PM2 (supporting pathogenic) + BP4 (supporting benign), resulting in a classification of Variant of Uncertain Significance.
