Investigation heme oxygenase-1 polymorphism with the pathogenesis of preeclampsia.

ABSTRACT

Objectives: The involvement of oxidative stress in the pathophysiology of preeclampsia (PE) has been already suggested. In this present study, we aimed to investigate the association of the genetic frequency of heme oxygense-1 (HMOX1) polymorphism with PE in Chinese Han women.Methods: We researched the genetic distribution of rs2071746 polymorphism in HMOX1 by the TaqMan allelic discrimination real-time PCR between 1235 PE patients and 1720 healthy women.Results: We found there were't significant differences in the distribution of HMOX1 rs2071746 polymorphism in PE compared to the control group (rs2071746, genotype χ2 = 0.282, P = 0.869 and allele χ2 = 0.027, P = 0.869, OR = 1.009, 95% = 0.909-1.120).Conclusion: The rs2071746 polymorphism in HMOX1 might not be related to PE in Chinese women, although further investigations should be conducted to confirm our findings.
