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]
DACT3-AS1 (HGNC:44120): (DACT3 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2024The c.2488C>T (p.H830Y) alteration is located in exon 18 (coding exon 18) of the PRKD2 gene. This alteration results from a C to T substitution at nucleotide position 2488, causing the histidine (H) at amino acid position 830 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
