Genes affected

PLCD3 (HGNC:9061): (phospholipase C delta 3) This gene encodes a member of the phospholipase C family, which catalyze the hydrolysis of phosphatidylinositol 4,5-bisphosphate to generate the second messengers diacylglycerol and inositol 1,4,5-trisphosphate (IP3). Diacylglycerol and IP3 mediate a variety of cellular responses to extracellular stimuli by inducing protein kinase C and increasing cytosolic Ca(2+) concentrations. This enzyme localizes to the plasma membrane and requires calcium for activation. Its activity is inhibited by spermine, sphingosine, and several phospholipids. [provided by RefSeq, Jul 2008]

The c.1136G>T (p.R379L) alteration is located in exon 7 (coding exon 7) of the PLCD3 gene. This alteration results from a G to T substitution at nucleotide position 1136, causing the arginine (R) at amino acid position 379 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
