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) associated with increased risk of neonatal respiratory distress syndrome (RDS).

Primary Outcome Measures:
  • Statistical association of rare, functionally disruptive genomic variant with RDS [ Time Frame: 4 weeks ]
    Using custom exon capture, next generation sequencing, and in silico prediction of function, discover statistical associations between gene loci with excess, rare, functionally disruptive variants and risk of neonatal respiratory distress syndrome.

Secondary Outcome Measures:
  • Statistical associations between risk of neonatal respiratory distress syndrome and excess, rare functional variants in gene pathways [ Time Frame: 4 weeks ]
    Using custom exon capture, next generation sequencing, in silico prediction of functional variants, and Metacore for pathway construction, identify statistical associations between risk of neonatal respiratory distress syndrome and pathways with excess, rare functional variants
