Moreover, SNPs in the FGFR4 gene were shown to be associated with bronchopulmonary dysplasia (BPD) and respiratory distress syndrome (RDS), whereas SNPs in the FGFR2 gene had no association with neither BPD nor RDS (Rezvani et al., 2013). This evidence concerns the gene FGFR4 and bronchopulmonary dysplasia.
