Abstract

The association between apolipoprotein E (apo E) gene polymorphism and ischemic cerebrovascular disease (ICVD) has been controversial. These controversies may be due to inaccurate classification of patients and ethnic differences. We investigated the association between apo E genotypes and ICVD patients by case-control study in a Korean population. The association between apo E polymorphism and ICVD was examined in 121 patients with ICVD and 132 controls without ICVD. The E3/E4 phenotype was more frequent in control subjects (23.8%) than in patients (13.0%) (p<0.05). The E2/E3 phenotype was more frequent in patients (14.8%) than in control subjects (10.8%), but the difference was not statistically significant (p>0.05). These results suggest that the E4 allele may be a protective factor against early vascular morbidity, and the E2 allele may be a risk factor for cerebrovascular morbidity.
