sFLT-1 has been implicated in the pathogenesis of HDP. We aimed to examine the role of maternal and fetal polymorphisms in risk of HDP and severe-spectrum disease.
Cases of HDP (143) and controls (169) from mother-baby dyads were recruited at the Los Angeles County Women's and Children's Hospital (WCH). Cases of severe disease (99) and controls (31) from mother-father-baby triads were recruited through HELLP syndrome websites. Four sFLT-1 SNPs (rs7993594, rs3751395, rs7983774, and rs664393) were genotyped. Data was analyzed using a log-linear regression model in the Haplin package in R.
Maternal double dose of the A allele (rs7993594) exhibited a nominally significant increased risk of HDP (RR = 3.52, 95% CI 1.08, 11.20). In the severe-spectrum cohort, a marginally significant protective effect among mothers carrying infants with a single dose of the A allele (rs7993594) was observed (RR = 0.59, 95% CI 0.36, 0.98) and double-dose maternal carriage of the G-t-G-G haplotype increased risk of severe disease (RR = 4.13, 95% CI 1.22, 13.80).
The maternal rs7993594 A allele appears to be associated with increased risk of HDP. Double-dose maternal carriage of the G-t-G-G haplotype increased risk of severe disease whereas the fetal rs7983774 A allele appears to be associated with decreased risk.
可溶性血管内皮生长因子受体-1（sFLT-1）与妊娠期高血压疾病（HDP）的发病机制有关。我们旨在研究母体和胎儿基因多态性在HDP及严重程度疾病风险中的作用。
在洛杉矶县妇女儿童医院（WCH）招募母婴二元组中的HDP病例（143例）和对照（169例）。通过HELLP综合征网站招募母婴父三元组中的严重疾病病例（99例）和对照（31例）。对4个sFLT-1单核苷酸多态性（SNP，rs7993594、rs3751395、rs7983774和rs664393）进行基因分型。使用R语言中Haplin软件包的对数线性回归模型分析数据。
母体携带双剂量A等位基因（rs7993594）患HDP的风险名义上显著增加（相对风险[RR]=3.52，95%置信区间[CI]1.08，11.20）。在严重程度疾病队列中，观察到携带单剂量A等位基因（rs7993594）婴儿的母亲有边缘显著的保护作用（RR=0.59，95%CI 0.36，0.98），而母体携带双剂量G-t-G-G单倍型会增加严重疾病风险（RR=4.13，95%CI 1.22，13.80）。
母体rs7993594 A等位基因似乎与HDP风险增加有关。母体携带双剂量G-t-G-G单倍型会增加严重疾病风险，而胎儿rs7983774 A等位基因似乎与风险降低有关。
