Description

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 126 of the TRIM32 protein (p.Ala126Val). This variant is present in population databases (rs755478136, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with TRIM32-related conditions. ClinVar contains an entry for this variant (Variation ID: 650525). 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.
