This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 442 of the FAM46A protein (p.Asn442Ser). This variant is present in population databases (rs749658715, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with FAM46A-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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. -
