Abstract
We report the case of a preterm infant who died at 10 months of age with severe bronchopulmonary dysplasia (sBPD) with refractory pulmonary hypertension and respiratory failure who had striking histologic features compatible with the diagnosis of alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV) but without genetic confirmation of the diagnosis. We further demonstrate dramatic reductions in lung FOXF1 and TMEM100 content in sBPD, suggesting common mechanistic links between ACDMPV and sBPD with impaired FOXF1 signaling.
