Abstract Background Preeclampsia, a complex hypertensive disorder unique to pregnancy, significantly impacts maternal and fetal health worldwide, with a prevalence of 2–8%. This condition results from a complex interplay of genetic, environmental, and immunological factors. Aim and objectives This study aims to investigate the genetic predispositions to preeclampsia, focusing on specific gene polymorphisms among pregnant women at Central Hospital Auchi, Nigeria. Materials and methods We examined the endothelial nitric oxide synthase (eNOS), vascular endothelial growth factor (VEGF), angiotensin-converting enzyme (ACE), and tumor necrosis factor-alpha (TNF-α) genes in 200 pregnant women, equally divided between preeclamptic patients and normotensive controls. Results The eNOS G894T polymorphism was significantly associated with preeclampsia, with the T allele nearly doubling the risk. The VEGF C936T polymorphism's T allele also indicated a higher risk. The D allele in the ACE gene's insertion/deletion (I/D) polymorphism significantly increased the risk, as did the A allele in the TNF-α G308A polymorphism. Conclusions These findings highlight the importance of genetic factors in preeclampsia and suggest that genetic screening could improve risk stratification and early detection. Future research should integrate genetic, epigenetic, and environmental data to understand preeclampsia's multifaceted nature and develop targeted therapies. This study underscores the potential of personalized medicine in managing and reducing the risks associated with preeclampsia.
