Pheochromocytoma in a 2.75‐year‐old‐girl with a germline von Hippel–Lindau mutation Q164R

Pheochromocytoma in a 2.75‐year‐old‐girl with a germline von Hippel–Lindau mutation Q164R Pheochromocytomas are rare tumors of the adrenal gland occurring sporadically or as part of familial cancer syndromes. Here we report on the case of a pheochromocytoma due to the germline missense mutation c.491A>G (Q164R) in exon 3 of the von Hippel–Lindau gene in a girl as young as 2.75 years. Extended analyses of her relatives showed that the mutation occurred de novo in the patient's father who was subsequently diagnosed with bilateral pheochromocytomas and a retinal angioma. To the best of our knowledge, this is the youngest patient presenting with pheochromocytoma so far described in the literature. The same VHL mutation has been reported in a patient who developed a pheochromocytoma at the age of 10 years; therefore, for known VHL Q164R mutation carriers, we suggest screening for pheochromocytoma beginning at 2 years of age. © 2010 Wiley‐Liss, Inc. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Medical Genetics Part A Wiley

Abstract

Pheochromocytomas are rare tumors of the adrenal gland occurring sporadically or as part of familial cancer syndromes. Here we report on the case of a pheochromocytoma due to the germline missense mutation c.491A>G (Q164R) in exon 3 of the von Hippel–Lindau gene in a girl as young as 2.75 years. Extended analyses of her relatives showed that the mutation occurred de novo in the patient's father who was subsequently diagnosed with bilateral pheochromocytomas and a retinal angioma. To the best of our knowledge, this is the youngest patient presenting with pheochromocytoma so far described in the literature. The same VHL mutation has been reported in a patient who developed a pheochromocytoma at the age of 10 years; therefore, for known VHL Q164R mutation carriers, we suggest screening for pheochromocytoma beginning at 2 years of age. © 2010 Wiley‐Liss, Inc.
