RCV002009429 | SCV002290011 | uncertain significance | Chuvash polycythemia; Von Hippel-Lindau syndrome | 2021-04-13 | 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. This variant disrupts the p.Glu70 amino acid residue in VHL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 9829912, 25715769, 25078357, 17661816, 25562111, 27439424, 19408298, 19270817, Invitae). 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. This variant has not been reported in the literature in individuals with VHL-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with aspartic acid at codon 70 of the VHL protein (p.Glu70Asp). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and aspartic acid. |

| Ambry Genetics | RCV004681399 | SCV005179672 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-05-28 | criteria provided, single submitter | clinical testing | The p.E70D variant (also known as c.210G>T), located in coding exon 1 of the VHL gene, results from a G to T substitution at nucleotide position 210. The glutamic acid at codon 70 is replaced by aspartic acid, 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. Based on the available evidence, the clinical significance of this variant remains unclear. |
