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 c.150C>G (p.D50E) alteration is located in exon 1 (coding exon 1) of the WNK2 gene. This alteration results from a C to G substitution at nucleotide position 150, causing the aspartic acid (D) at amino acid position 50 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
