Apoe2 binds poorly to the ldlr , and homozygous inheritance of the apoe2 allele is strongly associated with type iii dyslipoproteinemia . apoe2 and apoe4 are associated with hypercholesterolemia and atherosclerosis ( as ) . the apoe4 is also associated with higher incidence and earlier age of onset of late onset familial alzheimer ' s disease ( ad ) , whereas apoe2 may have the opposite effect Apoe _ 2与ldlr结合能力很差，与型高脂血症关联。 apoe _ 2和apoe _ 4与高胆固醇血症、动脉粥样硬化( as )等疾病有关， apoe _ 4还是老年痴呆( ad )的高发风险因子，而apoe _ 2则对预防老年痴呆病的发生具有积极作用。
