HLA-G多态性与妊娠高血压综合征相关性研究

目的 :探索HLA G与妊娠高血压综合征的发生是否存在关联。方法 :采用非同位素地高辛标记的寡核苷酸探针杂交技术 ,对上海地区 5 4例妊娠高血压综合征 (Pregnancy inducedHypertension ,PIH)病人和 14 6例正常孕妇对照进行HLA G等位基因分型。结果 :在正常对照组及妊高征组中均可检出 9种HLA G等位基因 :G 0 10 11、G 0 10 12、G 0 10 13、G 0 10 18、G 0 10 3、G 0 10 4 1、G 0 10 4 2、G 0 10 4 3、G 0 10 5N。其中G 0 10 11在PIH病人和正常对照组中均是最常见的等位基因 ,各占31 4 8%和 37 33% ,其次是G 0 10 13分别为 2 5 0 0 %和 2 0 2 1% ,G 0 10 4 1分别占 18 5 2 %和 18 4 9%。检出的各等位基因在两组之间比较均无显著性差异。结论 :HLA G等位基因多态性与妊娠高血压综合征的发生可能没有直接关联

Study on association of PIH with HLA-G allele

Objective:To investigate the mechanism of association between Pregnancy induced Hypertension and HLA G.Methods:The distribution and frequencies of HLA G alleles were analyzed in 54 PIH patients and 146 random healthy controls with nonradioactive digoxigenin labeled PCR SSO method.Results:The results showed that the same nine HLA G alleles were detected and the G*01011 was the commonest allele with the frequency of 31.38% and 37.33% respectively in both PIH and controls groups,the next was G*01013,25.00% and 20.21% separately.Statistic analysis showed that the frequencies of HLA G alleles were similar to in the two groups and there was no significant difference between PIH patients and controls.Conclusion:These data suggest that there is no significant detectable relation between the HLA G polymorphism and PIH.
