Objectives: To investigate the role of LPL-Ser447Ter and Asn291Ser polymorphisms in the predisposition to different types of preeclampsia, as well as the contribution to the lipid profile and the prognosis of preeclampsia.
Methods: 125 women with preeclampsia and 131 normal pregnant women were genetically screened using PCR-restriction enzyme analysis.
Results: We found an increased risk for mild and severe preeclampsia in carriers of the negative Ser447/Ser447 genotype. An increased risk for severe preeclampsia in carriers of the Asn291Ser polymorphism was seen. In mild and severe preeclampsia, carriers of the negative Ser447/Ser447 genotype had increased TG and LDL-C levels and decreased HDL-C levels as compared with carriers of the Ser447Ter polymorphism. The presence of the Asn291Ser polymorphism influenced the higher TG and LDL-C levels and the lower HDL-C levels in mild preeclampsia and the higher TG and LDL-C levels in severe preeclampsia. Women with severe preeclampsia, carriers of the Ser447/Ser447 genotype and women with mild preeclampsia, carriers of the Asn291Ser polymorphism, delivered at a lower gestational age neonates with a lower birth weight compared to women carriers of this polymorphism.
Conclusions: The LPL variants are associated with severe preeclampsia and influence the lipid profile and pregnancy outcome in mild and severe preeclampsia.
