Epidemiology of Surfactant Protein-B Deficiency
In Brief
An observational study for Lung Diseases and 3 related conditions. Completed, enrolled 5,176 participants across 1 site.
Detailed Summary
The purpose of this study is to test the hypothesis that excess, rare, functionally disruptive single nucleotide polymorphisms (SNPs) characterize genes (e.g., the surfactant protein-B gene)(SFTPB) and gene networks (e.g., the pulmonary surfactant metabolic network or other gene networks that regulate alveolar type 2 cell function) associated with increased risk of neonatal respiratory distress syndrome (RDS).
