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. 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. This variant has not been reported in the literature in individuals affected with SIN3B-related conditions. This variant is present in population databases (rs368592710, gnomAD 0.007%). This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 121 of the SIN3B protein (p.Gln121Arg). -
