Abstract
- Objective: To check whether individual or combined mutated genotypes for Ala-9Val (Mn-SOD) and Arg213Gly (EC-SOD) are associated with preeclampsia; to check the influence of the mutated genotypes on the degree of severity and perinatal outcome of preeclampsia.<br />Methods: We genotyped 97 pregnant women (47 with preeclampsia and 50 normal pregnant women) using PCR-RFLP analysis.<br />Results: The Val/Val (Mn-SOD) genotype (OR 5.99, p = 0.004) but not the Gly/Gly (EC-SOD) genotype (OR 4.23, p = 0.027) was significantly associated with preeclampsia. Higher frequency of both polymorphisms in women with preeclampsia (42.55%) compared to normal pregnant women (8%). Higher frequency of women diagnosed with PIH (27.27%, OR 4.31), mild (50%, OR 11.5) and severe preeclampsia (37.5%, OR 6.9) positive for both polymorphism compared to control women (8%). There was a statistically significant difference in gestational age at delivery according to Mn-SOD (Ala/Ala vs. Val/Val, 39 ± 1.41 weeks vs. 32.77 ± 3.7 weeks) and EC-SOD genotypes (Arg/Arg vs. Gly/Gly, 37.05 ± 3.18 weeks vs. 31.5 ± 3.84 weeks). There also was a statistically significant difference in birth weight according to Mn-SOD (grams, Ala/Ala vs. Val/Val, 3080 ± 481.66 vs. 2376.92 ± 916.88) and EC-SOD genotypes (grams, Arg/Arg vs. Gly/Gly, 2934.09 ± 662.14 vs. 2080 ± 721.19).<br />Conclusions: Our study demonstrates a relationship between these two mutated genes, the clinical severity and the perinatal outcome of preeclampsia.
