Abstract:
This study examined the association of a common polymorphic allele (25G) of the low-density lipoprotein receptor-related protein1 (LRP1) gene with myocardial infarction (MI). The genotypes of LRP1 25CG (rs35282763) were determined in 347 MI patients and 347 age- and sex-frequency-matched controls from an unrelated Chinese Han population. Factor VIII (FVIII) levels were measured in the MI patients and controls by chromogenic assay and enzyme-linked immunosorbent assay (ELISA). The results showed that LRP1 25CG (rs35282763) genotype distribution did not differ significantly between patients (n=206 for 25CC, n=122 for 25CG) and controls (n=191 for 25CC, n=126 for 25CG; P>0.05). The 25G allele was not associated with a reduced risk of MI (P>0.05). Further stratifications for age, sex, and other cardiovascular risk factors did not affect the negative findings. It was concluded that the presence of the G allele at the 25CG (rs35282763) polymorphism of the LRP1 is not associated with a reduced risk of MI, and genotyping for LRP1 25CG (rs35282763) polymorphism is not useful in assessing the individual risk of MI.
