Genes affected

VPS45 (HGNC:14579): (vacuolar protein sorting 45 homolog) Vesicle mediated protein sorting plays an important role in segregation of intracellular molecules into distinct organelles. Genetic studies in yeast have identified more than 40 vacuolar protein sorting (VPS) genes involved in vesicle transport to vacuoles. This gene is a member of the Sec1 domain family, and shows a high degree of sequence similarity to mouse, rat and yeast Vps45. The exact function of this gene is not known, but its high expression in peripheral blood mononuclear cells suggests a role in trafficking proteins, including inflammatory mediators. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2013]

This sequence change replaces arginine, which is basic and polar, with lysine, which is basic and polar, at codon 481 of the VPS45 protein (p.Arg481Lys). This variant is present in population databases (rs151292369, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with VPS45-related conditions. ClinVar contains an entry for this variant (Variation ID: 541272). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The lysine 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. -
