Identification of SEPP1 polymorphisms is not a genetic risk factor for preeclampsia in Chinese Han women: A clinical trial and experimental study: Erratum

BACKGROUND 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 χ = 2.417, P = .299 and allele χ = 0.197, P = .761, odds ratio 1.049, 95% confidence interval 0.744-1.151; rs230813: genotype χ = 3.273, P = .195 and allele χ = 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.
