Genes affected

USP8 (HGNC:12631): (ubiquitin specific peptidase 8) This gene encodes a protein that belongs to the ubiquitin-specific processing protease family of proteins. The encoded protein is thought to regulate the morphology of the endosome by ubiquitination of proteins on this organelle and is involved in cargo sorting and membrane trafficking at the early endosome stage. This protein is required for the cell to enter the S phase of the cell cycle and also functions as a positive regulator in the Hedgehog signaling pathway in development. Pseudogenes of this gene are present on chromosomes 2 and 6. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

This sequence change replaces arginine with tryptophan at codon 133 of the USP8 protein (p.Arg133Trp). The arginine residue is weakly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is present in population databases (rs202135045, ExAC 0.09%). This variant has not been reported in the literature in individuals affected with USP8-related conditions. 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: "Benign"; Align-GVGD: "Class C0"). 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. -
