ABSTRACT
Background: The purpose of the study was to determine the relationship between angiotensin II type 1 receptor at position+1166 [AT1R+1166A/C; rs5186] and angi-otensin II type 2 receptor at position+1675 [AT2R+1675A/G; rs5194] gene poly-morphisms with preeclampsia in an Iranian women population
Methods: 430 women were recruited in this study including 212 preeclamptics and 218 healthy women. PCR-RFLP method was used for genotyping the polymorphisms. Chi square and Fisher exact test were used for comparing case and control groups. The p<0.05 was considered statistically significant
Results: The frequency of genotypes of the AT1R gene and AT2R gene was similar in preeclampsia and normal pregnancy. There were no significant differences in geno-type and also allele frequencies between preeclamptics and healthy women regarding the two studied polymorphisms. AT1R/AT2R genotypes combination study indicated that there was a statistically significant difference between preeclamptics and healthy women. AC/AG combination was significantly decreased, while CC/AA combination showed significant increase in patients compared with the healthy women [p<0.01]
Conclusion: The present study showed that the genetic polymorphisms within AT1R and AT2R genes may be associated with susceptibility to preeclampsia in Iranian women
