RCV000226904 | SCV000285505 | uncertain significance | Chuvash polycythemia; Von Hippel-Lindau syndrome | 2023-08-11 | criteria provided, single submitter | clinical testing | Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt 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. ClinVar contains an entry for this variant (Variation ID: 238114). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 3 of the VHL protein (p.Arg3Trp). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with VHL-related conditions. |
Ambry Genetics | RCV002418000 | SCV002678759 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-05-07 | criteria provided, single submitter | clinical testing | The p.R3W variant (also known as c.7C>T), located in coding exon 1 of the VHL gene, results from a C to T substitution at nucleotide position 7. The arginine at codon 3 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. |
