Genes affected

STK39 (HGNC:17717): (serine/threonine kinase 39) This gene encodes a serine/threonine kinase that is thought to function in the cellular stress response pathway. The kinase is activated in response to hypotonic stress, leading to phosphorylation of several cation-chloride-coupled cotransporters. The catalytically active kinase specifically activates the p38 MAP kinase pathway, and its interaction with p38 decreases upon cellular stress, suggesting that this kinase may serve as an intermediate in the response to cellular stress.

The c.1326A>C (p.E442D) alteration is located in exon 14 (coding exon 14) of the STK39 gene. This alteration results from a A to C substitution at nucleotide position 1326, causing the glutamic acid (E) at amino acid position 442 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
