KL-6 (a lung injury marker) was increased in infants in the umbilical cord blood samples in infants who went on to develop BPD (n = 50 vs. non-BPD n = 24) (79) and was also useful as a predictor of moderate/severe BPD at 1 week of postnatal life (80). The gene discussed is MUC1; the disease is bronchopulmonary dysplasia.
