BACKGROUND: Preeclampsia is a major pregnancy complication characterized by hypertension and systemic dysfunction, significantly impacting maternal health. The study highlights the complex immune responses triggered during pregnancy, particularly focusing on the interleukin 17 signaling pathway in PE pathogenesis. This study examines the association between two genetic variants-IL-17RA rs4819554 and IL-17RC rs708567-and the risk of preeclampsia.
METHODS: In this case-control study, a cohort of 470 women including 240 diagnosed with PE and 230 control women were examined utilizing polymerase chain reaction-restriction fragment length polymorphism techniques (PCR-RFLP). Additionally, a new computational study was conducted to prediction the possible roles of these polymorphisms.
RESULTS: The research found significant correlations between the AG and GG genotypes of IL-17 RA rs4819554 and the TT genotype of IL-17RC rs708567 with increased preeclampsia risk, particularly severe cases. Notably, combining these polymorphisms further elevated the risk, with the IL-17 RA rs4819554 GG/ IL-17RC rs708567 CC genotype associated with a six-fold increase in late-onset PE risk. These findings underscore the potential of IL-17 receptor gene variants as biomarkers for preeclampsia susceptibility and suggest a complex interplay of genetic factors influencing inflammation during pregnancy. The IL-17RA rs4819554 gene polymorphism may result in differential allelic expression, according to in-silico study. Additionally, bioinformatics study revealed that the IL-17RC rs708567 SNP will result in a notable change to its secondary structure and physicochemical characteristics.
CONCLUSIONS: This study provides significant insights into the genetic mechanisms underlying preeclampsia, highlighting the necessity for further investigation into these genetic variants and their implications for pregnancy outcomes.
