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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with TP53RK-related conditions. This variant is present in population databases (rs773814837, gnomAD 0.01%). This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 42 of the TP53RK protein (p.Gly42Val). -
