【摘要】 分析59名中国人58条无遗传关系的X染色体,发现中国人DX13上Bg1Ⅱ多态性位点出现的频率为81%,明显高于国外同类研究结果。以DX13/Bg1 Ⅱ RFLPs为遗传标志对9个甲型血友病家系进行连锁分析,4个家系中的甲型血友病基因可以得到确定。

【Abstract】 Genomic DNA fragment DX13 (DXS15) is located in q28 region of X chromosome that also contains the hemophilia A locus. Fifty-eight unrelated X chromosomes in 59 Chinese were studied. Results show that frequency in Chinese of Bgl E polymorphic site in DX13 is 81%, being significantly higher than that of Western population. By use of the RFLPs, 9 families with hemophilia A were analysed.
