The p.A175E variant (also known as c.524C>A), located in coding exon 1 of the ALPK3 gene, results from a C to A substitution at nucleotide position 524. The alanine at codon 175 is replaced by glutamic acid, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear. -
