Genes affected

PLD2 (HGNC:9068): (phospholipase D2) The protein encoded by this gene catalyzes the hydrolysis of phosphatidylcholine to phosphatidic acid and choline. The activity of the encoded enzyme is enhanced by phosphatidylinositol 4,5-bisphosphate and ADP-ribosylation factor-1. This protein localizes to the peripheral membrane and may be involved in cytoskeletal organization, cell cycle control, transcriptional regulation, and/or regulated secretion. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011]

The c.821C>T (p.T274M) alteration is located in exon 9 (coding exon 8) of the PLD2 gene. This alteration results from a C to T substitution at nucleotide position 821, causing the threonine (T) at amino acid position 274 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
