RESUMO
[Objective]To investigate associations between the functional polymorphisms of signal transducer and activator of transcription 4 (STAT4) gene and preeclampsia.[Methods]PCR-restriction fragment length polymorphism was used to genotype rs10181656 and rs16833431 local polymorphism in 228 preeclampsia cases and 179 normal controls.[Results](1)The frequencies of rs10181656C/G were 35.96%,46.37%in genotype C/C,47.81%,44.69%in genotype C/G and 16.23%,8.94%in genotype G/G between preeclampsia patients and normal controls. They reached statistical difference (P = 0.031). There was different distribution in two alleles(C and G)between preeclampsia patients and normal controls(P=0.009).(2)There was no different distribution in 3 genotypes(C/C,C/T,T/T)and 2 alleles(C and T)of rs16833431 C/T between preeclampsia patients and normal controls(P =0.508,0.461).[Conclusions]Functional polymorphisms of the rs10181656 locus could associate with the preeclampsia. The polymor-phisms of the rs16833431 locus could not associate with the preeclampsia.
