Diaphragmatic Eventration is related to distal spinal muscular atrophy 1 and pneumothorax, primary spontaneous. An important gene associated with Diaphragmatic Eventration is PIK3CA (Phosphatidylinositol-4,5-Bisphosphate 3-Kinase Catalytic Subunit Alpha), and among its related pathways/superpathways is Kallmann syndrome. Affiliated tissues include liver and small intestine, and related phenotypes are nervous system and growth/size/body region
