Item Are the polymorphisms in ACE and ESR1 genes associated with preeclampsia occurrence?(2019) Lopes, Ana Cristina dos Santos; Perucci, Luiza Oliveira; Evangelista, Fernanda Cristina Gontijo; Godoi, Lara Carvalho; Sabino, Adriano de Paula; Silva, André Talvani Pedrosa da; Dusse, Luci Maria Sant'Ana; Alpoim, Patrícia NessrallaItem Association among ACE, ESR1 polymorphisms and preeclampsia in Brazilian pregnant women.(2019) Lopes, Ana Cristina dos Santos; Perucci, Luiza Oliveira; Evangelista, Fernanda Cristina Gontijo; Godoi, Lara Carvalho; Sabino, Adriano de Paula; Gomes, Karina Braga; Silva, André Talvani Pedrosa da; Dusse, Luci Maria Sant'Ana; Alpoim, Patrícia NessrallaBackground: Genetic, immune and environmental factors are involved in preeclampsia (PE) etiopathogenesis. Considering that hypertension and poor placental perfusion are important features in PE, polymorphisms in the angiotensin-converting enzyme (ACE) and estrogen nuclear receptor 1 (ESR1) genes could be involved in the predisposition and/or development of the disease. The aim of this study was to evaluate if polymorphisms in ACE and ESR1 genes were associated with PE occurrence. Material and Methods: This case-control study included 209 Brazilian pregnant women (107 with severe PE and 102 normotensive controls). The polymorphisms were investigated by polymerase chain reaction (PCR) followed by polyacrylamide gel electrophoresis. Results: No significant difference between PE versus normotensive pregnant women, as well as early versus late PE, was observed when compared the allelic and genotypic frequencies of insertion/deletion polymorphism in intron 16 of the ACE gene and the single nucleotide polymorphisms (SNPs - rs2234693 and rs9340799) of the ESR1 gene. Conclusion: This pioneer study involving Brazilian women showed no association among the studied polymorphisms and PE, which suggests that ins/del ACE and SNPs ESR1 do not contribute to this disease occurrence in Brazil.
