Apolipoprotein E Polymorphism in Ischemic and Hemorrhagic Stroke / 대한해부학회지

ABSTRACT

There is an evidence for a role of apolipoprotein E (APOE) in atherosclerosis, coronary heart disease and carotid artery stenosis. Morbidity of carotid artery atherosclerosis is higher in persons carrying an epsilon4 allele, but the association of cerebrovascular disease and apoE genotype is controversial. We studied the association between APOE genotype and allele (epsilon2, epsilon3, epsilon4) frequency and stroke. We evaluated APOE genotype in 133 first -ever stroke patients and 111 healthy controls. We also estimated the risk factors of stroke such as hypertension, diabetes and lipid profiles in both groups. APOE genotypes were analyzed by polymerase chain reaction. APOE genotypes and allele distributions were not different in patients and controls. There is also no difference of APOE allele frequencies between ischemic small artery occlusive disease and hypertensive subcortical intracerebral hemorrhage. We concluded that the APOE -epsilon4 allele is not associated with stoke including ischemic and hemorrhagic stroke.
