ATP-binding cassette G1 (ABCG1), one of the members of the large protein family of ABC transporters involved in the active transport of lipophilic molecules, and apolipoprotein E (APOE), the protein involved in the metabolism of lipids in the body, both affect blood lipid levels and might contribute to the development of atherosclerosis and cardiovascular disease [8, 9].
