Panel-included key genes that encode proteins related to hypertriglyceridemia are LPL (lipoprotein lipase), APOC2 (apolipoprotein C2), APOA5 (apolipoprotein A5), LIPC (Lipase C), GPIHBP1 (glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1), and LMF1 (lipase maturation factor 1), and, later, GPD1 (glycerol-3-phosphate dehydrogenase 1) was also included. This evidence concerns the gene LPL and hypertriglyceridemia.
