Biochemical investigation of FOXP3 genetic polymorphism and its association with biochemical parameters in pre-eclampsia patients.

This study addresses the pivotal question of the association between FOXP3 gene polymorphism and pre-eclampsia (PE), employing the Tetra ARMS PCR method for analysis. PE, a multifaceted disorder marked by hypertension and organ dysfunction during pregnancy, led to an exploration of FOXP3 due to its integral role in immune regulation and its implication in various autoimmune and inflammatory disorders. The primary objective was to discern the relationship between FOXP3 gene polymorphism (rs2232365) and the risk of PE. Recruiting 200 PE patients and 100 healthy pregnant women as controls, genomic DNA was extracted from peripheral blood samples, and FOXP3 promoter region polymorphism was meticulously examined using the Tetra ARMS PCR method. The results revealed significant differences in FOXP3 gene polymorphism between PE patients and healthy controls. Specifically, certain alleles and genotypes were more frequent in PE patients, suggesting a potential genetic predisposition to this disorder. Our findings showed that rs2232365 A/G variant was found to be associated with PE under the overdominance model [OR=1.89, CI 95%= 0.99-3.60, P<0.05]. The heterozygous genotype (A/G) of FOXP3 (rs2232365) was associated with increasing the level of clinical and biochemical markers in mild and severe PE patients when compared to controls. Thus, the FOXP3 (rs2232365) A/G variant can be considered a substantial risk factor for PE.
