LPL (Lipoprotein Lipase): LPL is a gene that encodes an enzyme crucial for the metabolism of triglyceride-rich lipoproteins. It hydrolyzes triglycerides in lipoproteins such as chylomicrons and VLDL, facilitating the release of free fatty acids for energy use or storage. Mutations in LPL can cause hyperlipidemia and increase the risk of pancreatitis and cardiovascular disease.
