Objective:
The purpose of this study was to determine whether genetic variability in oxidative stress-related enzymes contributes to individual preeclampsia susceptibility differences.
Study Design:
Polymorphisms in the cytochrome P450 (CYP)1A1 (MspI), CYP1A1(Ile/Val), glutathione S-transferase (GST)M1, GSTT1, myeloperoxidase (MPO), and manganese superoxide dismutase (MnSOD) genes were evaluated by polymerase chain reaction (PCR) or PCR-restriction fragment length polymorphism (RFLP) in 214 healthy controls with an uncomplicated obstetric history, and in 121 preeclampsia patients. Chi2 analyses were used to statistically evaluate differences.
Results:
No significant differences in the CYP1A1(MspI) or CYP1A1(Ile/Val) genotypes were observed between the healthy controls and the preeclampsia patients (chi2 = 1.43, P = 0.49 versus chi2 = 1.54, P = 0.46). The GSTM1 homozygous null type and GSTT1 homozygous null type were no differences in the patients and controls (chi2 = 0.01, P = 0.92 versus chi(2) = 0.31, P = 0.57), and no significant differences in the polymorphisms of the MPO and MnSOD genotypes were found between the patients and controls (chi2 = 2.00, P = 0.37 versus chi2 = 0.07, P = 0.96).
Conclusion:
Polymorphisms in the oxidative stress-related genes (CYP1A1, GSTM1, GSTT1, MPO, MnSOD) do not seem to be risk factors for preeclampsia.
