For example, Apoa4 plays a role in fat digestion and absorption, cholesterol metabolism, and atherosclerosis; Pla2g12a functions in Glycerophospholipid metabolism, ether lipid metabolism, arachidonic acid metabolism, linoleic acid metabolism, and fat digestion and absorption; Elovl7, Slc27a4, Hilpda, and Fabp4 are all involved in lipid metabolism (Supplementary Table S1). This evidence concerns the gene PLA2G12A and atherosclerosis.
