Abstract
Preeclampsia (PE), one of the most serious complications of pregnancy, is characterized by endothelial dysfunction and hypertension. Gastrointestinal complications of preeclampsia can occur and have the risk of being life-threatening for the mother and fetus. Genetic predisposition is a risk factor for PE. In this context, the genotype rates and allele frequencies of the STOX1 gene rs1341667 (Y153H) polymorphism in peripheral blood and placental tissues (decidua, umblical cord) of 25 PE patients and 25 healthy controls were examined by Light Cycler® Nano Real Time PCR Instrument (Roche Applied Systems). The STOX1 gene rs1341667 polymorphism exists in three different genotypes in humans: TT (wild type), TC (heterozygous) and CC (mutant). When the genotype frequencies of peripheral blood and placenta samples were compared between patients and controls, there was no difference (P > 0.05). The genotype results of the decidua and umblical cord samples, analyzed from the same placenta in all cases, were the same. There was no difference between allele frequencies of the patients and controls (P > 0.05). In our study, rs1341667 polymorphism was detected in peripheral blood and placental tissues of preeclamptic mothers. However, this polymorphism was also detected in healthy pregnant women peripheral bloods and their placental tissues. There was no difference between the frequencies of the C allele, which is the risk allele, in both blood and placental tissues of controls and PE patients. In this regard, we cannot support the view that the relevant polymorphism predisposes to preeclampsia. However, our study has small number of patients. This polymorphism needs to be analyzed in large populations.
