Zusammenfassung
Lipids are highly diverse molecules that are traditionally best known for their role in the formation of biological membranes and cellular systems and as a way to store energy. In the last decade, lipids have taken a more center stage in apoptosis, cell signaling, inflammation, immunity and inborn errors of metabolism (IEMs). Inborn errors of lipoprotein metabolism are a group of genetic disorders exemplified by changes in plasma lipids due to defects in the protein lipid-carriers (lipoproteins), lipoprotein receptors, or enzymes responsible for the hydrolysis and clearance of lipoprotein-lipid complexe. The proteins responsible for the maintenance of normal plasma and tissue lipids, which are primarily triglycerides and free and esterified cholesterol, include the apolipoproteins A-I, A-II, A-IV, A-V, B, C-I, C-II, C-III, and E with key enzymes including lipoprotein lipase (LPL), hepatic triglyceride lipase (LIPC), lecithin cholesterol acyltransferase (LCAT), and cholesterol ester transfer protein (CETP); and key receptors being the low-density lipoprotein receptor (LDL-R) for LDL-Cholesterol, and the ATP-binding cassette transporter 1 (ABC1A) for HDL-Cholesterol levels. A number of genetic abnormalities of lipoprotein metabolism have been described in childhood.
