rs199846198

Description

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 538 of the RELA protein (p.Ala538Val). This variant is present in population databases (rs199846198, gnomAD 0.07%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with RELA-related conditions. ClinVar contains an entry for this variant (Variation ID: 1015419). 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 valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
