This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 297 of the NSMCE3 protein (p.Pro297Ser). This variant is present in population databases (rs776476342, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with NSMCE3-related conditions. 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. -
