The relationship between placental gene polymorphisms and preeclampsia risk in Russian women

To study the associations of polymorphisms of the NDRG1 gene, which is differentially expressed in the placenta, with the risk of preeclampsia (PE) development. The study group included 997 women: 366 pregnant women with preeclampsia and 631 women with physiological pregnancy. Clinical and laboratory examination of pregnant women was carried out in the Perinatal Center of the Belgorod Regional Clinical Hospital of St. Joasaph. DNA was isolated from peripheral venous blood lymphocytes by phenol-chloroform extraction. All women underwent typing of four single nucleotide polymorphisms of the N-myc downstream regulated gene 1 (NDRG1). The analysis of SNPs associations with the development of preeclampsia was performed using logistic regression analysis within the framework of additive, dominant and recessive genetic model
