Description

This variant has not been reported in the literature in individuals affected with TOPORS-related conditions. 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 38 of the TOPORS protein (p.Gly38Val).
