ClinVar

Description

In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Gly93 amino acid residue in VHL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 8707293, 9329368, 12000816, 17661816, 17922902). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 expected to disrupt VHL protein function. ClinVar contains an entry for this variant (Variation ID: 223174). This variant is also known as 490G>C (p.Gly93Arg). This missense change has been observed in individual(s) with VHL-related conditions (PMID: 20660572, 23660872; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 93 of the VHL protein (p.Gly93Arg).
