Description

This sequence change replaces glycine with glutamic acid at codon 267 of the SLC22A5 protein (p.Gly267Glu). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and glutamic acid. This variant is present in population databases (rs775430253, ExAC 0.04%). This variant has not been reported in the literature in individuals affected with SLC22A5-related conditions. ClinVar contains an entry for this variant (Variation ID: 555629). 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: "Probably Damaging"; Align-GVGD: "Class C15"). 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.
