Phospholipase A2, group VII (platelet-activating factor acetylhydrolase, plasma), also known as PLA2G7, is a human gene.^[1]

The PLA2G7 gene encodes platelet-activating factor (PAF) acetylhydrolase (EC 3.1.1.47), a secreted enzyme that catalyzes the degradation of PAF to inactive products by hydrolysis of the acetyl group at the sn-2 position, producing the biologically inactive products LYSO-PAF and acetate.[supplied by OMIM]^[1]
