Variant summary
The NM_000551.4(VHL):c.262T>A (p.Trp88Arg) 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: "SCV002743251: Based on internal structural analysis, W88R is at a putative HIF1 binding interface and the variant is moderately destabilizing to the local structure and more disruptive than known variants in the region (Shmueli MD et al. PLoS ONE, 2014 Oct;9:e109864" and additional evidence is available in ClinVar. The variant position is a cancer hotspot (cancerhotspots.org): 11 samples carry this exact amino acid change out of 44 samples with a variant at this residue. This exact variant is curated in the UniProt human variants database as Uncertain Significance, associated with Adenomas and Adenocarcinomas; it is also listed as a COSMIC curated somatic variant.

Classification according to ACMG Germline Pathogenicity v2019
Our verdict: Pathogenic. The variant received 22 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); SCV002743251: Based on internal structural analysis, W88R is at a putative HIF1 binding interface and the variant is moderately destabilizing to the local structure and more disruptive than known variants in the region (Shmueli MD et al. PLoS ONE, 2014 Oct;9:e109864; Van Molle I et al. Chem. Biol., 2012 Oct;19:1300-12). | ||
| PM1Mutational hot spot or critical domain | Missense neighbourhood hotspot (≥2 P/LP within ±8 AA, OR ≥ 5 vs. background) — PM1; In-domain: 0 pathogenic, 0 benign rare missense variants.; ±8 AA neighbourhood: 28 pathogenic, 8 benign (OR vs. background: 16.8). | ||
| 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 0.000226 by highest known P/LP ClinVar AF 0.000226) — PM2 moderate. | ||
| PP3Computational evidence supports damaging effect | Germline meta computational scorer (REVEL/MetaRNN/BayesDel) predicts damaging effect — moderate evidence (PP3); Splicing verdict: not pathogenic.; Germline computational verdict: pathogenic (Moderate). | ||
| PP5Reputable source reports pathogenic | ClinVar 2-star pathogenic — strong (PP5); ClinVar germline classification: Pathogenic/Likely Pathogenic, 2 star(s). |
