The APOE gene, located on chromosome 19, is a gene that helps in the creation of apolipoprotein E to help to form molecules called lipoproteins, this protein forms the lipo-proteins by combining with lipids in the body. By forming lipo-proteins, apolipoprotein E participates in the responsibility of managing cholesterol and carrying it, and other fats, through the bloodstream. By maintaining cholesterol, it helps to act as a prevention against disorders that can hurt the cardiovascular system, such as heart disease. While there are three different variations of the gene, the most common allele is e3. Allele e3 is characteristic of over half the general population (2015). As for how mutations in the APOE gene are related to health conditions,
