The Association Between LPCAT1 Genetic Polymorphism and Stress Biomarkers in Neonatal Respiratory Distress Syndrome

Aims of the Research Primary: 1. Measure the levels of stress biomarkers in full and preterm neonates with normal and complicated pregnancies and to study the influence of delivery mode on their cord blood concentrations. 2. Test the association between LPCAT1 genetic polymorphism and the levels of these biomarkers in neonates suffering from RDS. 3. Study the relation between LPCAT1 genetic polymorphism and the risk/severity of neonatal respiratory distress syndrome. Secondary: 1\) Help understanding the possible etiology and pathogenesis of neonatal RDS. 2) Help the possibility of early detection, diagnosis and management. 3\) Help to decrease mortality and morbidity in selective cases. 4) Understand the individual variability in the susceptibility to development of pulmonary pathologies.
