The APOE gene provides instructions for making a protein called apolipoprotein E (APOE) which is involved in the metabolism of lipids (fats) in the body. There are three common forms of the APOE gene, known as e2, e3, and e4. The e3/e3 genotype is the most common, and is considered the "normal" form of the APOE gene. The e4 allele may be associated with an increased risk of developing Alzheimer's disease, as well as other medical conditions such as cardiovascular disease and diabetes.
