The NM_000551.4(VHL):c.241C>G (p.Pro81Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene VHL is a tumor suppressor gene (CancerMine: 345 TSG, 114 oncogene, 46 driver citations). The gene VHL is a known oncogene (CancerMine: 345 TSG, 114 oncogene, 46 driver citations). The gene VHL is a cancer driver gene (CancerMine: 345 TSG, 114 oncogene, 46 driver citations). 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 Uncertain Significance (★). A different missense at the same amino acid position has been reported as Pathogenic/Likely Pathogenic in ClinVar: p.P81L: Pathogenic/Likely_pathogenic (ClinVar VariationId 36899, 2 stars) Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.P81= (synonymous): Benign/Likely_benign (ClinVar VariationId 3468038, 2 stars); p.P81= (synonymous): Benign/Likely_benign (ClinVar VariationId 2927601, 2 stars); p.P81= (synonymous): Benign (ClinVar VariationId 4071324, 1 star); p.P81S: Benign (ClinVar VariationId 2233, 3 stars) The variant has been observed in cBioPortal in 1 sample across 1 study and 1 cancer type; somatic enrichment level: NONE (Observed in at most one deduplicated cBioPortal case.).

Genes affected
VHL (HGNC:12687): (von Hippel-Lindau tumor suppressor) This gene encodes a component of a ubiquitination complex. The encoded protein is involved in the ubiquitination and degradation of hypoxia-inducible-factor (HIF), which is a transcription factor that plays a central role in the regulation of gene expression by oxygen. In addition to oxygen-related gene expression, this protein plays a role in many other cellular processes including cilia formation, cytokine signaling, regulation of senescence, and formation of the extracellular matrix. Variants of this gene are associated with von Hippel-Lindau syndrome, pheochromocytoma, erythrocytosis, renal cell carcinoma, and cerebellar hemangioblastoma. [provided by RefSeq, Jun 2022]

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 5 points.

O3Absent or very rare in population
Absent or extremely rare in gnomAD (AC ≤ 2) — O3 moderate; GnomAD: AF = absent, AC = 0 — absent/extremely rare (O3 moderate [+2])
O5Same location/impact as known oncogenic
Different AA at same residue with oncogenic evidence (or germline P/LP in TSG), or same AA change SCI Tier II Potential — Supporting (O5); ClinVar same-AA oncogenic/T1: false | ClinVar same-AA SCI tier: — | CGI same-AA oncogenic: false | TSG: true | ClinVar same-AA germline P/LP: false | CIViC LOF: false | ClinVar diff-AA oncogenic: false | ClinVar diff-AA germline P/LP: true
O6Computational evidence supports deleterious effect
Computational evidence supports a deleterious/oncogenic effect; Missense variant — primary computational scorer supports an oncogenic/deleterious effect
O7Mutational hotspot or critical domain
Supporting: cancerhotspots.org hit, critical domain, or missense neighbourhood hotspot; No cancerhotspots.org hit at this position; UniProt domain: 0 pathogenic, 0 benign.; ±8 AA neighbourhood: 39 pathogenic, 6 benign (OR vs. background: 30.4); Variant does not impact splicing — splice-hotspot path not applicable
