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]

ACMG classification

Verdict is Pathogenic. Variant got 16 ACMG points.

• PM1: In a strand (size 5) in uniprot entity VHL_HUMAN there are 7 pathogenic changes around while only 0 benign (100%) in NM_000551.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.994
• PP5: Variant 3-10146531-A-G is Pathogenic according to our data. Variant chr3-10146531-A-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 223199.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr3-10146531-A-G is described in Lovd as [Pathogenic].

This sequence change replaces arginine with glycine at codon 120 of the VHL protein (p.Arg120Gly). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and glycine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in individuals affected with von Hippel-Lindau disease (PMID: 11688393, 25867206, 20151405). ClinVar contains an entry for this variant (Variation ID: 223199). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
