Von Hippel-Lindau syndrome Uncertain:3
- -
- -
This missense variant replaces tyrosine with cysteine at codon 185 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 identified in an individual affected with clear-cell renal cell carcinoma (PMID: 25583177). This variant has been identified in 6/282836 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. -
not provided Uncertain:3
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in an individual with clear cell renal cell carcinoma (PMID: 25583177); This variant is associated with the following publications: (PMID: 26933808, 25583177) -
The VHL c.554A>G; p.Tyr185Cys variant (rs561874453; ClinVar Variation ID: 223232) is reported in the literature in the germline of an individual with a clear cell renal carcinoma (Beuselinck 2015). This variant is observed in the general population with an overall allele frequency of 0.002% (6/282836 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.632). Due to limited information, the clinical significance of this variant is uncertain at this time.

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. -
VHL-related disorder Uncertain:1
The VHL c.554A>G variant is predicted to result in the amino acid substitution p.Tyr185Cys. This variant has been reported in an individual with clear cell renal carcinoma (Table S4, Germline, Beuselinck et al. 2015. PubMed ID: 25583177). It has been also been reported in a glioblastoma tumor specimen (Table S2, Xiu et al. 2016. PubMed ID: 26933808). This variant is reported in 0.0046% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-10191561-A-G) and has conflicting interpretations of likely benign and uncertain significance (https://preview.ncbi.nlm.nih.gov/clinvar/variation/223232/). 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 tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 185 of the VHL protein (p.Tyr185Cys). This variant is present in population databases (rs561874453, gnomAD 0.004%). This missense change has been observed in individual(s) with clear cell renal cell carcinoma (PMID: 25583177). ClinVar contains an entry for this variant (Variation ID: 223232). 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) indicates that this missense variant is expected to disrupt VHL protein function with a positive predictive value of 95%. 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. -
