  • Title: Familial pheochromocytoma associated with a novel mutation in the von Hippel-Lindau gene.
    Author: Gross DJ, Avishai N, Meiner V, Filon D, Zbar B, Abeliovich D.
    Journal: J Clin Endocrinol Metab; 1996 Jan; 81(1):147-9. PubMed ID: 8550742.
    Abstract:
    We report a three generation, 25 member kindred with familial pheochromocytoma. Seven subjects of generations I and II had pheochromocytoma, in five of the seven, the tumors were bilateral, and in two of the seven, the tumors were both adrenal and extraadrenal. One patient also had a carotid body chemodectoma, and one patient had a malignant adrenal tumor and abdominal paraganglioma. In the patient with the chemodectoma, a cerebellar hemangioblastoma became manifest 25 yr after his initial diagnosis with pheochromocytoma, leading only then to a clinical diagnosis of von Hippel-Lindau disease (VHL). A mutational analysis of the VHL gene revealed a novel nucleotide 709 G-->T transversion present in all affected subjects and in four presymptomatic children. In familial pheochromocytoma the diagnosis of VHL should be considered, even when the formal criteria for diagnosis of the syndrome are lacking.
