This sequence change replaces isoleucine with leucine at codon 52 of the RUSC2 protein (p.Ile52Leu). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and leucine. This variant is present in population databases (rs771426449, ExAC 0.002%). This variant has not been reported in the literature in individuals with RUSC2-related conditions. 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 leucine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. -
