It is worth noting that all cholangiocarcinoma cases, liver hepatocellular carcinoma cases, pancreatic adenocarcinoma cases, pheochromocytoma, paraganglioma cases, and diffuse large B-cell lymphoma with genetic alteration (>2% frequency) had copy number amplification of FCGR3A (Figure 9(a)). Here, FCGR3A is linked to hereditary pheochromocytoma-paraganglioma.
