This sequence change replaces glutamine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 57 of the RUSC2 protein (p.Gln57Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RUSC2-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 C25"). 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. -
