Description

This sequence change replaces serine with arginine at codon 175 of the SLC52A3 protein (p.Ser175Arg). The serine residue is weakly conserved and there is a moderate physicochemical difference between serine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with SLC52A3-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
