NOS3 and newborn respiratory distress syndrome: They found that the status of rs2070744 allele C carrier(TC+CC) was significantly more frequent in infants with RDS, BPD, and IVH compared to control patients (15.3 vs. 7.3%, p = 0.03) and represents a significant risk factor for the development of these pathologies [6] Our data are in partial agreement with these findings because we did not observe any relationship between the polymorphism and the risk of severe RDS and IVH, but we could confirm that TC+CC rs2070744 eNOS genotypes are a risk factor for BPD.
