The MDM2 promoter T309G polymorphism was associated with preeclampsia susceptibility.

ABSTRACT: Preeclampsia (PE) is a hypertensive disorder of pregnancy in which abnormal proliferation and apoptosis of placenta trophoblast has a pivotal role in its pathophysiology. The aim of the current study was to examine the association between Mouse Double Minute 2 (MDM2) T309G and 40 bp insertion/deletion (I/D) polymorphisms and PE risk.A case-control study was conducted on 208 PE women and 164 healthy pregnant women matching age, sex, and ethnicity. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and PCR methods were used for genotyping.The MDM2 309GG genotype was associated with PE, and this genotype was found to be a risk factor for PE. There was no association between the MDM2 I/D polymorphism and PE. The haplotype-based association analysis revealed no association between MDM2 T309G and 40 bp I/D polymorphisms and PE. The frequency of TT-DD and GG-DD combined genotypes were significantly higher in PE women with marginal P values (P = 0.046).The MDM2 309GG genotype was associated with higher risk of PE. The TT-DD and GG-DD combined genotypes were higher in PE women.
