Aim: The possible effects of maternal and placental ANRIL polymorphisms on preeclampsia were examined. Methods: The maternal blood of 315 preeclamptic and 317 control women and the placentas of 103 preeclamptic and 133 control women were enrolled in the study. ANRIL polymorphisms were genotyped using a PCR-RFLP method. Results: The maternal ANRIL rs1333048C variant showed a relationship with a lower risk of preeclampsia in codominant and dominant models. The maternal ANRIL rs4977574G variant had a relationship with a lower risk of preeclampsia in codominant and recessive models. There was an association between the placental rs1333048C variant and a lower risk of preeclampsia in codominant and dominant models. Conclusion: Maternal ANRIL rs1333048C and rs4977574G variants and placental rs1333048 variant showed a relationship with a lower risk of preeclampsia.
