Genes affected

PLCD1 (HGNC:9060): (phospholipase C delta 1) This gene encodes a member of the phospholipase C family. Phospholipase C isozymes play critical roles in intracellular signal transduction by catalyzing the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) into the second messengers diacylglycerol (DAG) and inositol triphosphate (IP3). The encoded protein functions as a tumor suppressor in several types of cancer, and mutations in this gene are a cause of hereditary leukonychia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]

The c.1942G>T (p.A648S) alteration is located in exon 12 (coding exon 12) of the PLCD1 gene. This alteration results from a G to T substitution at nucleotide position 1942, causing the alanine (A) at amino acid position 648 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
