This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 13 of the LSR protein (p.Gly13Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LSR-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
