Genes affected

PLCD4 (HGNC:9062): (phospholipase C delta 4) This gene encodes a member of the delta class of phospholipase C enzymes. Phospholipase C enzymes play a critical role in many cellular processes by hydrolyzing phosphatidylinositol 4,5-bisphosphate into two intracellular second messengers, inositol 1,4,5-trisphosphate and diacylglycerol. Expression of this gene may be a marker for cancer. [provided by RefSeq, Jan 2011]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.292C>T (p.R98C) alteration is located in exon 4 (coding exon 3) of the PLCD4 gene. This alteration results from a C to T substitution at nucleotide position 292, causing the arginine (R) at amino acid position 98 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
