FOXF1 and alveolar capillary dysplasia with misalignment of pulmonary veins: Since many non-coding deletions in or near the FOXF1 gene locus cause human ACDMPV8, identification of pathogenic enhancers critical for FOXF1 gene expression is important to understand and diagnose the pathobiology of ACDMPV, enabling better genetic screening for ACDMPV which currently relies primarily on exome DNA sequencing.
