This variant has not been reported in the literature in individuals affected with ALPK3-related conditions. This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 181 of the ALPK3 protein (p.Ala181Ser). This variant is not present in population databases (gnomAD no frequency). 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 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. -
