| Ambry Genetics | RCV002323305 | SCV002626821 | uncertain significance | Hereditary cancer-predisposing syndrome | 2020-03-26 | criteria provided, single submitter | clinical testing | The p.V137M variant (also known as c.409G>A), located in coding exon 2 of the VHL gene, results from a G to A substitution at nucleotide position 409. The valine at codon 137 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is well 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. |

RCV003775817 | SCV004594812 | uncertain significance | Chuvash polycythemia; Von Hippel-Lindau syndrome | 2023-04-08 | criteria provided, single submitter | clinical testing | 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. 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: 1737815). This variant has not been reported in the literature in individuals affected with VHL-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 137 of the VHL protein (p.Val137Met). |
