Is preeclampsia associated with higher frequency of HSP70 gene polymorphisms?
AIM: To evaluate the possible association of three different HSP70 gene polymorphisms with preeclampsia. STUDY DESIGN: HSPA1A G(190)C, HSPA1B A(1267)G and HSPA1L T(2437)C polymorphisms were analyzed from blood samples of 72 women with preeclampsia and of 70 healthy pregnant women as controls by PCR-RFLP method. RESULTS: HSPA1B (1267)GG and HSPA1L (2437)CC genotypes occurred more frequently in preeclamptic patients compared to healthy controls (p<0.002 [RR: 4.38, 95% CI: 1.56-12.28]) and (p<0.03 [RR: 1.31, 95% CI: 1.03-1.67]), respectively. Significant difference was found in the distribution of HSPA1B A(1267)G genotype between the preeclamptic and control group (p<0.004 [RR: 0.67, 95% CI: 0.51-0.88]). Distribution of HSPA1A G(190)C was similar in the preeclamptic and control group. In controls, genotype distribution of HSPA1A G(190)C and HSPA1L T(2437)C was in Hardy-Weinberg equilibrium, while this criterion was not fulfilled for HSPA1B A(1267)G. CONCLUSION: We concluded that HSPA1B (1267)GG and HSPA1L (2437)CC genotypes were more frequent among preeclamptic than control patients, suggesting that these genotypes may play a role in the susceptibility for preeclampsia.[1]References
