Labcorp Genetics (formerly Invitae), Labcorp RCV000471735 SCV000553400 uncertain significance Chuvash polycythemia; Von Hippel-Lindau syndrome 2023-08-30 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 9 of the VHL protein (p.Asp9Ala). 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. ClinVar contains an entry for this variant (Variation ID: 411971). 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.
Ambry Genetics RCV002436462 SCV002744859 likely benign Hereditary cancer-predisposing syndrome 2023-12-07 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
