-DNA source: maternal and neonatal-73 SNPs in glucocorticoid-related genes including drug-metabolizing enzymes (CYP3A5 and CYP3A7), transport proteins (IPO13 and ABCB1), signaling proteins (ADCY9) and hormone receptors (CRHR1 and NRC31)Association of genotypes with neonatal respiratory outcomes other than RDS (MV, surfactant use, BPD) by logistic regression-. Here, ABCB1 is linked to bronchopulmonary dysplasia.
