Genes affected

PLA2G3 (HGNC:17934): (phospholipase A2 group III) This gene encodes a protein that belongs to the secreted phospholipase A2 family, whose members include the bee venom enzyme. The encoded enzyme functions in lipid metabolism and catalyzes the calcium-dependent hydrolysis of the sn-2 acyl bond of phospholipids to release arachidonic acid and lysophospholipids. This enzyme acts as a negative regulator of ciliogenesis, and may play a role in cancer development by stimulating tumor cell growth and angiogenesis. This gene is associated with oxidative stress, and polymorphisms in this gene are linked to risk for Alzheimer's disease. [provided by RefSeq, Apr 2014]

The c.1097G>T (p.R366L) alteration is located in exon 5 (coding exon 5) of the PLA2G3 gene. This alteration results from a G to T substitution at nucleotide position 1097, causing the arginine (R) at amino acid position 366 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
