SEPP1 encodes selenoprotein P, which involved in oxidative stress and plays an important role in the development of preeclampsia (PE). The aim of this study was to investigate the association between PE and genetic variants of SEPP1 in Chinese Han women.Methods:
In all, 2434 unrelated pregnant women were recruited, including 1034 PE cases and 1400 normal pregnant controls. TaqMan allelic discrimination real-time PCR method was used to genotype the 2 polymorphisms of rs7579 and rs230813 in SEPP1.Results:
No statistically significant difference in genotypic or allelic frequencies were found at the 2 genetic variants in SEPP1 between PE patients and controls (rs7579: genotype χ2 = 2.417, P = .299 and allele χ2 = 0.197, P = .761, odds ratio 1.049, 95% confidence interval 0.744–1.151; rs230813: genotype χ2 = 3.273, P = .195 and allele χ2 = 0.252, P = .615, odds ratio 0.971, 95% confidence interval 0.864–1.091). There were also no statistically significant differences in genetic distributions between mild/severe PE or early/late-onset PE and control subgroups.Conclusion:
Our data indicate that the 2 genetic variants of rs7579 and rs230813 in SEPP1 may not play a role in the pathogenesis of PE in Chinese Han Women.
