Results showed that there were no statistically significant differences in the distributions of the -455G/A genotype and allele frequency between the Uygurs and the Han. Plasma fibrinogen levels in cerebral infarction patients among the Uygurs and the Han were higher than those among healthy subjects. In particular, the frequencies of the -455G/A AA and -148C/T TT genotypes were significantly higher than in healthy subjects. Individuals carrying the A or T allele had a higher incidence of cerebral infarction compared with those carrying the G or C allele. Our experimental findings indicate that the -148C/T and -455G/A polymorphisms are associated with cerebral infarction in Xinjiang Uygur and Han Chinese subjects. The susceptibility- conferring alleles are -148T and -455A, and the susceptibility-conferring genotype is -455G/A + AA. 关 键 词：等位基因频率 新疆维吾尔族 纤维蛋白原 中国人群 脑梗塞 多态性 汉族 基因型频率
