Submissions by phenotype
not provided Uncertain:1
This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 595 of the VPS33A protein (p.Pro595Thr). This variant is present in population databases (rs200158890, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with VPS33A-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. -
