This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 182 of the ALPK3 protein (p.Gly182Arg). This variant is present in population databases (no rsID available, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with ALPK3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1414237). 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. -

The p.G182R variant (also known as c.544G>C), located in coding exon 1 of the ALPK3 gene, results from a G to C substitution at nucleotide position 544. The glycine at codon 182 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis.Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
