Abstract

Abstract : Abstract: Preeclampsia is a complex genetic disorder and its pathogenesis remains to be investigated. Single nucleotide polymorphisms serve important roles in genetic predisposition. The present study aimed to explore the association between runt-related transcription factor 3 ( RUNX3 ) gene polymorphisms in severe preeclampsia (SPE) and clinical features. A total of 417 participants were enrolled in the present study. The rs2236852, rs7528484 and rs760805 polymorphisms of the RUNX3 gene were tested using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Clinical information of patients and controls was collected. Relationship between clinical feature and different genotype was analyzed. Compared with rs2236852 GG genotype carriers, the odds ratios (OR) for the risk of SPE were 2.26 [95% confidence interval (CI), 1.24–4.12; P = .023] in AA genotype carriers. A significantly increased risk of SPE was associated with AG/AA genotypes compared with GG genotypes (OR, 1.74; 95% CI, 1.11–2.75; P = .015). AA homozygote carriers with SPE exhibited lower birth weight, shorter birth length and reduced incidence of hypoproteinemia compared with AG heterozygote carriers ( P <.05). A significantly increased risk of SPE was determined to be associated with the rs7528484 CC genotype in codominant and recessive models (CC vs TT: OR, 3.70, 95% CI, 1.31–10.43, P = .01; CC vs TT/TC: OR, 3.98, 95% CI, 1.46–10.87, P = .003). Patients carrying C-allele (TC + CC) presented increased systolic pressure and an increased incidence of neonatal pneumonia compared with TT homozygote carriers ( P <.05). Compared with rs760805 TT homozygote carriers, patients carrying AA homozygote exhibited significantly reduced 24 hours urinary protein levels, lower serum creatinine concentrations and a decreased incidence of neonatal asphyxia ( P <.05). The present study suggested a genetic association between RUNX3 gene polymorphisms and SPE. The data provided a novel insight to guide future investigations.
