CDH17 and cancer: For genes fully duplicated in BD‐cancer patients but not in BD‐only and healthy patients, functional enrichments identified include cell–cell adhesion (FDR = 2.2E‐16), sensory perception of chemical stimulus (FDR = 0.0021), olfactory receptor activity (FDR = 4.3E‐5), growth factor receptor binding (FDR = 0.027), peptidase regulator activity (FDR = 0.072), Wnt signaling pathway (FDR = 2.2e‐16), cadherin signaling pathway (FDR = 2.2e‐16), and cytokines and inflammatory response (FDR = 0.0039) (Fig. 3A,B).
