Von Hippel-Lindau syndrome Uncertain:4Benign:1
This variant is considered likely benign. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. -
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
This missense variant replaces arginine with glutamine at codon 210 of the VHL protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with glioma (PMID: 26580448). This variant has been identified in 17/282174 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. -
The VHL c.629G>A p.(Arg210Gln) missense change has a maximum subpopulation frequency of 0.016% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and to our knowledge functional studies have not been performed. This variant has been reported in individuals with pediatric glioma (PMID: 26580448, internal data). To our knowledge, this variant has not been reported in individuals with Von Hippel-Lindau disease. In summary, the evidence currently available is insufficient to determine the role of this variant in disease. It has therefore been classified as of uncertain significance. -

Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
- -
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
not specified Uncertain:1
- -
VHL-related disorder Uncertain:1
The VHL c.629G>A variant is predicted to result in the amino acid substitution p.Arg210Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.016% of alleles in individuals of African descent in gnomAD. In ClinVar this variant has conflicting interpretations of pathogenicity including uncertain significance and likely benign (https://www.ncbi.nlm.nih.gov/clinvar/variation/127828). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 210 of the VHL protein (p.Arg210Gln). This variant is present in population databases (rs138780791, gnomAD 0.01%). This missense change has been observed in individual(s) with a glioma (PMID: 26580448). ClinVar contains an entry for this variant (Variation ID: 127828). 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. -
