RCV001345511 | SCV001539634 | uncertain significance | Chuvash polycythemia; Von Hippel-Lindau syndrome | 2020-01-20 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with valine at codon 184 of the VHL protein (p.Leu184Val). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and valine. This variant has not been reported in the literature in individuals with VHL-related conditions. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). |
