Genes affected

PLA2G15 (HGNC:17163): (phospholipase A2 group XV) Lysophospholipases are enzymes that act on biological membranes to regulate the multifunctional lysophospholipids. The protein encoded by this gene hydrolyzes lysophosphatidylcholine to glycerophosphorylcholine and a free fatty acid. This enzyme is present in the plasma and thought to be associated with high-density lipoprotein. A later paper contradicts the function of this gene. It demonstrates that this gene encodes a lysosomal enzyme instead of a lysophospholipase and has both calcium-independent phospholipase A2 and transacylase activities. [provided by RefSeq, Jul 2008]

The c.532C>T (p.R178C) alteration is located in exon 5 (coding exon 5) of the PLA2G15 gene. This alteration results from a C to T substitution at nucleotide position 532, causing the arginine (R) at amino acid position 178 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
