Submissions by phenotype
Von Hippel-Lindau syndrome;C1837915:Chuvash polycythemia Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 179 of the VHL protein (p.Asp179Asn). This variant is present in population databases (rs767780451, gnomAD 0.0009%). This missense change has been observed in individual(s) with cerebellar haemangioblastoma (PMID: 17264095). ClinVar contains an entry for this variant (Variation ID: 419861). 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. -
not provided Uncertain:1
Not observed at a significant frequency in large population cohorts (Lek 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 14965365, 17264095, 18195360, 27424104, 21575214, 27568332, 20151405) -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.D179N variant (also known as c.535G>A), located in coding exon 3 of the VHL gene, results from a G to A substitution at nucleotide position 535. The aspartic acid at codon 179 is replaced by asparagine, an amino acid with highly similar properties. This variant, described as c.748G>A, was identified in one proband with a sporadic hemangioblastoma and also in this proband's 63-year-old first degree relative with no noted clinical features of Von Hippel-Lindau syndrome (Woodward ER et al. Brain, 2007 Mar;130:836-42). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
