Apolipoprotein E (apoE) is a 317-amino-acid long glycoprotein with three common isoforms (apoE2, apoE3, and apoE4) encoded by three apoE alleles (ε2, ε3, and ε4). These polymorphic forms arise from single amino acid substitutions with Cys and Arg interchanged at positions 112 and 158 (mature protein...
