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]

All of Us Research Program, National Institutes of Health

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant replaces arginine with lysine at codon 182 of the VHL protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with clear-cell renal cell carcinoma (PMID: 26228213). This variant has been identified in 2/251430 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Collection Method:clinical testing

VHL c.545G>A (rs749774529) is rare (<0.1%) in a large population dataset (gnomAD: 2/251430 total alleles; 0.0008%; no homozygotes) and has been reported in ClinVar (Variation ID: 231869). This variant has not been reported as a germline change in the literature, to our knowledge. Of two bioinformatics tools queried, two predicts that the substitution would be possibly damaging, while one predicts that it would be tolerated. The arginine residue at this position is evolutionarily conserved across the mammalian species assessed We consider the clinical significance of VHL c.545G>A to be uncertain at this time. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The VHL c.545G>A variant is predicted to result in the amino acid substitution p.Arg182Lys. This variant has been reported in a colorectal cancer specimen, an individual with clear‑cell renal cell carcinoma (Table 1, Kuwai et al. 2004. PubMed ID: 14965365; Table 4, Song et al. 2015. PubMed ID: 26228213). This variant is reported in 2 of ~251,000 alleles in gnomAD (http://gnomad.broadinstitute.org/variant/3-10191552-G-A) and is interpreted as uncertain significance in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/231869/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with lysine, which is basic and polar, at codon 182 of the VHL protein (p.Arg182Lys). This variant is present in population databases (rs749774529, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with VHL-related conditions. ClinVar contains an entry for this variant (Variation ID: 231869). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on VHL protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R182K variant (also known as c.545G>A), located in coding exon 3 of the VHL gene, results from a G to A substitution at nucleotide position 545. The arginine at codon 182 is replaced by lysine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
