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.1280A>C (p.Q427P) alteration is located in exon 13 (coding exon 13) of the STK39 gene. This alteration results from a A to C substitution at nucleotide position 1280, causing the glutamine (Q) at amino acid position 427 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
