About VHL

No gene-level summary was recorded for this case.

LYFE Sciences is an AI system, and it can make mistakes. Criteria may be applied incorrectly, sources may be misread, and a confident-looking classification can still be wrong. Double-check every criterion and its underlying evidence before relying on any call.

Per VHL VCEP v1.1.0, BP4 can be applied to assess lack of splicing impact. SpliceAI predicts no splicing effect (max delta score = 0.00, ≤0.1). Per VCEP guidance, SpliceAI alone may be applied when VarSeak is unable to accept the variant type. Missense predictors are explicitly excluded from BP4 per VCEP, but splicing assessment via SpliceAI is permitted. No splice effect is predicted.

NM_000551.3:c.104C>T (p.Ala35Val) is a missense variant in exon 1 of VHL, located in the N-terminal region prior to the p19 Met54 initiation site and outside all critical functional domains (Beta: AA63-154, Alpha: AA156-192, Second Beta: AA193-204).

This variant is present in gnomAD v4.1 at 16 of 1,544,318 alleles (allele frequency 1.04e-5) with a GroupMax Filtering Allele Frequency of 0.01103% (0.0001103) in the South Asian population, exceeding the VHL VCEP BS1 threshold of ≥0.00156% (BS1_Strong).

SpliceAI predicts no splicing impact (max delta score = 0.00), meeting the VHL VCEP BP4 criterion for lack of splice effect at Supporting strength.

REVEL score is 0.307, below the VHL VCEP PP3 threshold of ≥0.664. BayesDel score is -0.264 (benign direction). In silico predictors do not support pathogenicity.

No variant-specific functional data, segregation data, de novo observations, or proband phenotype data are available. The variant has not been reported in COSMIC and does not lie in a statistically significant mutational hotspot.

ClinVar classifies this variant as Uncertain significance (variation ID 526678) based on 3 clinical laboratory submissions with no expert panel review.

Applying the VHL VCEP v1.1.0 classification rules: BS1_Strong (1 strong benign) + BP4_Supporting (1 supporting benign) meets Rule 18 criteria for Likely Benign.

Statements for reports

The evidence statements recorded by the interpretation pipeline. They have not been reinterpreted by the page.

gnomAD v4.1

This variant is present in gnomAD v4.1 (AF= 1.03606e-05; MAF= 0.00104%, 16/1544318 alleles, homozygotes = 0) and has highest observed frequency in the South Asian population (AF= 0.000179229; MAF= 0.01792%, 15/83692 alleles, homozygotes = 0); grpmax FAF= 0.0001103.

gnomAD v2.1

This variant is present in gnomAD v2.1 (AF= 6.78444e-06; MAF= 0.00068%, 1/147396 alleles, homozygotes = 0) and has highest observed frequency in the South Asian population (AF= 4.47307e-05; MAF= 0.00447%, 1/22356 alleles, homozygotes = 0).

gnomAD-Canada

Absent from gnomAD-Canada v1.0.

ClinVar

This variant has been reported in ClinVar as Uncertain significance (3 clinical laboratories). (ClinVarID = 526678)

In silico

SpliceAI predicts no significant splice impact for this variant (max delta score = 0.00). REVEL score = 0.307. BayesDel score = -0.264275.

Functional

OncoKB did not identify variant-specific reviewed functional evidence for this variant; gene-level curated context is available for reviewer follow-up. VHL, an E3 ubiquitin ligase, is frequently mutated in renal cell carcinomas.

Somatic

This variant does not lie in a statistically significant hotspot. This variant has not previously been reported in somatic cancers (COSMIC).

Cancer Hotspots

This variant does not lie in a statistically significant hotspot.
