To explore the association between preeclampsia/eclampsia and maternal and fetal angiotensinogen SNPs. From January 2008 to October 2015, a case-parents/mother-control designed study was conducted among 347 preeclampsia/eclampsia cases and 700 controls to collect related information on their demographic characteristics and to detect the related angiotensinogen SNPs' genotypes. Both log-linear and unconditional logistic regression methods were employed to investigate the genetic effects of maternal/fetal angiotensinogen SNPs on preeclampsia/eclampsia. Multivariate binary unconditional logistic regression model and covariance were used to analyze the relationship between BMI before pregnancy, weight gain during pregnancy and overweight and obesity in preschool children. Both fetal angiotensinogen rs3789679 GA and AA genotype were associated with the reduced risks of preeclampsia/eclampsia, with s as 0.73 (95: 0.55-0.96) and 0.62 (95: 0.39-0.98), respectively. For fetal angiotensinogen rs2493132, individuals that carrying the TT genotype, presented a positive association with the risk of preeclampsia/eclampsia, with as 1.60 (95: 1.08-2.37). However, these associations were not statistically significant after the correction of the false discovery rate. It was observed that fetal rs3789679 could reduce the risk of preeclampsia/eclampsia (=0.73, 95: 0.55-0.96) under the dominant model (GA+AA/GG) while fetal rs2493132 increased the risk of preeclampsia/eclampsia (=1.66, 95: 1.13-2.44) under the recessive model (TT/CC+CT). Maternal rs5051 presented an association with preeclampsia/eclampsia (=1.33, 95: 1.01-1.76) under the dominant model (TC+CC/TT). Results from the dominant model showed that both fetal rs3789679 GA and AA genotype reduced the risk of preeclampsia/eclampsia and maternal rs5051 TC while CC genotype increased the risk of preeclampsia/eclampsia. Fetal rs2493132 TT genotype seemed to be associated with the risk of preeclampsia/eclampsia under the recessive model.
探讨子痫前期/子痫与母婴血管紧张素原单核苷酸多态性(SNP)之间的关联。2008年1月至2015年10月,在347例子痫前期/子痫病例和700例对照中开展了一项病例-父母/母亲对照设计研究,以收集其人口统计学特征的相关信息,并检测相关血管紧张素原SNP的基因型。采用对数线性和非条件逻辑回归方法研究母婴血管紧张素原SNP对子痫前期/子痫的遗传效应。使用多变量二元非条件逻辑回归模型和协方差分析孕前体重指数、孕期体重增加与学龄前儿童超重和肥胖之间的关系。胎儿血管紧张素原rs3789679的GA和AA基因型均与子痫前期/子痫风险降低相关,比值比分别为0.73(95%置信区间:0.55 - 0.96)和0.62(95%置信区间:0.39 - 0.98)。对于胎儿血管紧张素原rs2493132,携带TT基因型的个体与子痫前期/子痫风险呈正相关,比值比为1.60(95%置信区间:1.08 - 2.37)。然而,在错误发现率校正后,这些关联无统计学意义。观察到在显性模型(GA + AA/GG)下,胎儿rs3789679可降低子痫前期/子痫风险(比值比 = 0.73,95%置信区间:0.55 - 0.96),而在隐性模型(TT/CC + CT)下,胎儿rs2493132增加子痫前期/子痫风险(比值比 = 1.66,95%置信区间:1.13 - 2.44)。母亲rs5051在显性模型(TC + CC/TT)下与子痫前期/子痫相关(比值比 = 1.33,95%置信区间:1.01 - 1.76)。显性模型结果显示,胎儿rs3789679的GA和AA基因型均降低子痫前期/子痫风险,母亲rs5051的TC基因型降低风险,而CC基因型增加子痫前期/子痫风险。在隐性模型下,胎儿rs2493132的TT基因型似乎与子痫前期/子痫风险相关。
