FOXF1 and alveolar capillary dysplasia with misalignment of pulmonary veins: Since Foxf1WT/S52F mice developed alveolar capillary dysplasia phenotypically similar to human ACDMPV14, we used single cell RNA sequencing (scRNAseq) of lung tissue to identify molecular mechanisms through which the S52F FOXF1 mutation causes ACDMPV.
