title: Genetics of pheochromocytoma and paraganglioma: new developments.
abstract: Since 2000, several new susceptibility genes for hereditary pheochromocytoma or paraganglioma have been discovered. The aim of this review is to highlight how these discoveries have improved our knowledge on the mode of inheritance of these tumors and also on their molecular pathogenesis. Concerning this specific point, we will show that the different key players of tumorigenesis can converge on two pathways, the first being the hypoxia/angiogenesis pathway and the second being the control of neural crest cell development pathway. Finally, practical issues are considered; for us, it would be preferable to apply easy-to-identify clinical predictors to preselect patients eligible for molecular testing in order to improve the efficiency of these high-cost tests.
