Multiple predisposing factors\u2014including prematurity, low birth weight, and respiratory insufficiency\u2014have been consistently documented in the scientific literature. In this study, we investigated the influence of genetic polymorphisms in genes associated with the arachidonic acid\u2013prostaglandin metabolic pathway. Specifically, we analyzed polymorphisms in genes encoding phospholipase A2 (rs10798059, rs1549637, rs4375, rs1805017, rs1051931), cyclooxygenase-1 (rs1236913), prostaglandin synthase 2 (rs13283456), and the prostaglandin E2 receptor EP4 (rs4613763). The study cohort comprised 99 preterm neonates born between 24 and 32 weeks of gestation. Genetic analyses were performed to identify polymorphisms in the aforementioned genes. Statistical evaluation demonstrated that selected polymorphic were significantly associated with an increased risk of patent ductus arteriosus development. This study represents a preliminary step toward elucidating the contribution of genetic variability to the pathogenesis of patent ductus arteriosus. Improved understanding of these molecular mechanisms may facilitate the early identification of neonates at increased risk and support the implementation of targeted monitoring and preventive strategies in this high-risk population.<\/jats:p>","DOI":"10.3390\/ijms26199274","type":"journal-article","created":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T10:27:53Z","timestamp":1758623273000},"page":"9274","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Association Between Genetic Polymorphisms in the Prostaglandin Pathway and the Development of Patent Ductus Arteriosus in Preterm Infants"],"prefix":"10.3390","volume":"26","author":[{"given":"Marcin","family":"Minta","sequence":"first","affiliation":[{"name":"Department of Neonatology, Karol Marcinkowski University of Medical Sciences in Poznan, ul.
