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]

Collection Method:clinical testing

The c.377T>C (p.V126A) alteration is located in exon 4 (coding exon 3) of the PLCD4 gene. This alteration results from a T to C substitution at nucleotide position 377, causing the valine (V) at amino acid position 126 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
