Abstract
|
|
|
An increased risk for arterial thrombosis is associated with high plasma levels of coagulation
and fibrinolytic factors such as PAI-1 and FVII. In this study, the 4G/5G polymorphism in the
promoter of PAI-1 gene and Arg353-->Gln polymorphism in the FVII gene were analysed in 139
normal adults and 158 patients with coronary artery disease (CAD), and their association
with plasma lipid traits was investigated. There were no significant differences in the
allele frequencies of PAI-1 and FVII polymorphisms between control and patient groups. The
allelic distributions of both polymorphisms in Koreans were similar to those in Japanese
but significantly different from those in Caucasians. In the CAD group, the 4G homozygotes
of PAI-1 polymorphism showed significantly higher levels of total (p=0.0250) and LDL cholesterol
(p=0.0335) with individuals having other genotypes. However, FVII polymorphism showed no
association with lipid levels. In conclusion, the 4G/5G PAI-1 promoter polymorphism and
Arg353-->Gln FVII polymorphism are not major genetic risk factors for CAD in Koreans.
However, 4G allele of PAI-1 polymorphism revealed to be associated with the levels of
cholesterol, especially LDL cholesterol levels in CAD patients.
