Genes affected

ALPK2 (HGNC:20565): (alpha kinase 2) Predicted to enable ATP binding activity; protein serine kinase activity; and protein serine/threonine kinase activity. Involved in several processes, including epicardium morphogenesis; heart development; and negative regulation of Wnt signaling pathway involved in heart development. Acts upstream of or within regulation of gene expression. Colocalizes with basolateral plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The p.A2160E variant (also known as c.6479C>A), located in coding exon 12 of the ALPK2 gene, results from a C to A substitution at nucleotide position 6479. The alanine at codon 2160 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
