Variant summary
The NM_000059.4(BRCA2):c.9285C>A (p.Asp3095Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (REVEL) classifies this variant as likely damaging/oncogenic. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Pathogenic/Likely Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000953178: Experimental studies have shown that this missense change affects BRCA2 function (PMID:32444794).". A different missense at the same amino acid position has been reported as Pathogenic/Likely Pathogenic in ClinVar: p.D3095G: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 409512) Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.D3095A: Uncertain_significance (ClinVar VariationId 1330142, 1 star); p.D3095= (synonymous): Likely_benign (ClinVar VariationId 184910, 3 stars) The same amino acid change has been reported as oncogenic or likely oncogenic in a clinical somatic variant database. This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

Classification according to ACMG Germline Pathogenicity v2019
Our verdict: Pathogenic. The variant received 21 points.
| Apply | Criterion Code & Title / Strength | Rationale / Clinical Context | |
|---|---|---|---|
| PS1Same amino acid change as known pathogenic | Same AA change, ≥2-star ClinVar pathogenic — very strong (PS1); ClinVar contains 1 P/LP entry with the same amino acid change (highest review level: 2 stars). | ||
| PS3Functional studies show damaging effect | Well-established functional study supports damaging effect (PS3); SCV000953178: Experimental studies have shown that this missense change affects BRCA2 function (PMID: 32444794). | ||
| PM2Absent/extremely low in population databases | Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (base 0.0001, raised to 0.000139 by highest known P/LP ClinVar AF 0.000139) — PM2 moderate. | ||
| PM5Novel missense at known pathogenic residue | Different pathogenic missense at same AA residue in ClinVar (PM5); ClinVar contains a germline Pathogenic/Likely Pathogenic entry at the same amino acid position with a different amino acid change: p.D3095G: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 409512); Other variants at the same amino acid residue (not pathogenic): p.D3095A: Uncertain_significance (ClinVar VariationId 1330142, 1 star); p.D3095= (synonymous): Likely_benign (ClinVar VariationId 184910, 3 stars) | ||
| PP3Computational evidence supports damaging effect | Germline meta computational scorer (REVEL/MetaRNN/BayesDel) predicts damaging effect — supporting evidence (PP3); Splicing verdict: not pathogenic.; Germline computational verdict: pathogenic (Supporting). | ||
| PP5Reputable source reports pathogenic | ClinVar 2-star pathogenic — strong (PP5); ClinVar germline classification: Pathogenic/Likely Pathogenic, 2 star(s). |
