Answer

Once the diagnosis of pheochromocytoma is made, additional studies to rule out a familial syndrome may be indicated. Testing for every possible gene would be inappropriate and expensive; however, the following information can suggest which genetic tests to select [35] :

  • Biochemical profile of catecholamine secretion
  • Age of the patient
  • Site of the primary tumor
  • Family history
