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]

PLCD4 links:

ZNF142 (HGNC:12927): (zinc finger protein 142) The protein encoded by this gene belongs to the Kruppel family of C2H2-type zinc finger proteins. It contains 31 C2H2-type zinc fingers and may be involved in transcriptional regulation. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2013]

The c.1865G>C (p.S622T) alteration is located in exon 13 (coding exon 12) of the PLCD4 gene. This alteration results from a G to C substitution at nucleotide position 1865, causing the serine (S) at amino acid position 622 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
