摘　　要：目的观察我国北方汉族人β纤维蛋白原(BβFg)基因启动子区-455G/A多态性特点。方法应用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法测定153名大1连地区汉族人BβFg基因启动子区-455G/A等位基因及基因型。结果G-455等位基因频率为0.781,A-455等位基因频率为0.219,基因型GG、GA、AA的频率分别为0.588、0.386、0.026。结论大连地区汉族人群βFg基因-455G/A多态的等位基因及基因型频率与南方汉族人有差别,但与欧美白种人群相近。Objective To analyze the frequency of beta- fibrinogen gene -455G/A polymorphisms in Han nationality in Dalian Chinese and explore its characteristic in Han nationality in North China. Methods The beta-fibrinogen gene -455G/A polymorphisms for 153 individuals were analyzed by polymerase chain reaction-restrictive fragment length polymorphism （PCR-RFLP）. Results The frequencies of A^-455 , G^-455 allele were 0. 219 and 0. 781, respectively; and the frequencies of the genotype GG, GA, AA were 0. 588, 0.386, and 0.026, respectively. Conclusion The frequency of BβFg A455 allele in Han national population was consistent with Cauasians in Europe and America.
