Background
Apolipoprotein E (APOE) is a chylomicron lipoprotein which is essential for the metabolism of lipoproteins and lipid transport. The APOE gene has 3 alleles, designated APOE2, APOE3, and APOE4. The APOE allelic proteins differ by only one or two amino acids, however have different biological structures and functions. APOE3 is the most common and neutral allele. The APOE4 allele is linked with an increased risk for Alzheimer's Disease (AD) and coronary artery disease (CAD). The APOE4 protein morphology decreases the ability of APOE4 to clear beta-amyloid protein from the brain, resulting in AD progression. The APOE2 allele is linked with type III hyperlipoproteinemia, which is characterized by defects in the clearance of plasma lipoproteins, however APOE2 may have a protective effect against AD.
