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.2156C>T (p.T719I) alteration is located in exon 15 (coding exon 14) of the PLCD4 gene. This alteration results from a C to T substitution at nucleotide position 2156, causing the threonine (T) at amino acid position 719 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
