Abstract

Background: Preterm birth (PTB) is a major adverse pregnancy outcome and largely contributes to increasing neonatal and maternal mortality. Genetic and environmental factors may play an important role in the development of PTB. Numerous studies have shown that immune genes related to the immune system, such as IL-6, IL-10, and TNFα, are associated with the occurrence of PTB.
Objective: We examined genetic associations between IL-6 rs1800796, IL-10 rs1800872, and TNFα rs1800630 polymorphisms and PTB in Korean women.
Methods: In this study, 115 PTB patients and 147 controls were analyzed. The genotyping of three SNPs was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
Results: Our result showed that the rs1800872 polymorphism was significantly associated with the development of PTB in genotype frequency (odds ratio (OR) 1.71, 95% confidence interval (CI) 1.01?2.90, p?=?0.046). We also found a significant association in an analysis of combined genotypes (rs1800796 CC, rs1800872 CA, and rs1800630 CA) (OR 7.43, 95% CI 2.06?26.84, p?=?0.001). In a correlation analysis, rs1800630 A allele was significantly related with the increased birth weight (g) within PTB patients (p?=?0.005).
Conclusion: Our results imply possible relationships between the rs1800796, rs1800872, and rs1800630 polymorphisms and the development of PTB.
