Genes affected

PRKD2 (HGNC:17293): (protein kinase D2) The protein encoded by this gene belongs to the protein kinase D (PKD) family of serine/threonine protein kinases. This kinase can be activated by phorbol esters as well as by gastrin via the cholecystokinin B receptor (CCKBR) in gastric cancer cells. It can bind to diacylglycerol (DAG) in the trans-Golgi network (TGN) and may regulate basolateral membrane protein exit from TGN. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

The c.1934G>A (p.R645Q) alteration is located in exon 14 (coding exon 14) of the PRKD2 gene. This alteration results from a G to A substitution at nucleotide position 1934, causing the arginine (R) at amino acid position 645 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
