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