Abstract
Background/Aims: Accumulating evidence suggests that an excessive maternal systemic inflammatory response to pregnancy with exaggerated activation of the innate immune system plays a critical role in the development of preeclampsia (PE). In this study, we investigated whether polymorphisms in the Toll-like receptor 3 (TLR3) gene are associated with susceptibility to PE in the Chinese Han population. Methods: We recruited 987 PE patients and 1227 healthy pregnant women. Two polymorphisms (rs3775291 and rs3775296) located in TLR3 were genotyped by TaqMan allelic discrimination real-time PCR. The association between the genotype or allele frequencies and PE was examined using chi-square tests. Clinical data were compared between cases and controls using Student's t test. Results: No significant difference was determined in the genetic distribution of rs3775291 and rs3775296 between cases and controls. There were also no significant differences in the genotype and allele frequencies of either SNP between healthy pregnant women and patients with late or early onset PE, or with mild or severe PE. Conclusion: Although this is the first study of the association between TLR3 polymorphisms and preeclampsia, we found that TLR3 polymorphisms are unlikely to play a significant role in the development of preeclampsia in the Chinese Han population.
