Association between polymorphisms of prokineticin receptor (PKR1 rs4627609 and PKR2 rs6053283) and recurrent pregnancy loss
Abstract: Recurrent pregnancy loss (RPL) is a condition with complex etiologies, to which both genetic and environmental factors may contribute. During the last decade, studies indicated that the expression patterns of the prokineticin receptor (PKR1 and PKR2) are closely related to early pregnancy. However, there are few studies on the role of PKR1 and PKR2 in RPL. In this study, we purpose to investigate the association between polymorphisms of the prokineticin receptor (PKR1 rs4627609 and PKR2 rs6053283) and RPL on a group of 93 RPL cases and 169 healthy controls. Genotyping of the single nucleotide polymorphisms (SNPs) was performed using a Sequenom MassARRAY iPLEX system. The results revealed a significant association between PKR2 rs6053283 polymorphism and RPL (P=0.003), whereas no association was observed between PKR1 rs4627609 polymorphism and RPL (P=0.929) in the Chinese Han population.
Key words: Prokineticin receptor 1 (PKR1), PKR2, Polymorphism, Recurrent pregnancy loss
创新点：首次在中国汉族人群中进行前动力蛋白受体PKR1 rs4627609和PKR2 rs6053283的多态性与复发性流产关系的研究，并对其功能进行预测。
方法：共收集了93例复发性流产和169例健康对照者血液样本，提取基因组DNA，对PKR1 rs4627609和PKR2 rs6053283两个位点进行基因多态性分析，在两组样本中分析不同基因型与复发性流产的关系，并对PKR2 rs6053283位点的不同等位基因进行生物功能预测。
结论：PKR2 rs6053283的多态性与复发性流产相关；而PKR1 rs4627609的多态性与复发性流产之间不存在相关性。
