Genes affected

WNK2 (HGNC:14542): (WNK lysine deficient protein kinase 2) The protein encoded by this gene is a cytoplasmic serine-threonine kinase that belongs to the protein kinase superfamily. The protein plays an important role in the regulation of electrolyte homeostasis, cell signaling survival, and proliferation. Alternative splicing results in multiple transcript variants.

The p.P68R variant (also known as c.203C>G), located in coding exon 1 of the WNK2 gene, results from a C to G substitution at nucleotide position 203. The proline at codon 68 is replaced by arginine, 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 variant remains unclear. -
