    Journal: Chin Med Sci J; 2009 Dec; 24(4):197-201. PubMed ID: 20120764.
    Abstract:
    OBJECTIVE: To investigate the clinical and genetic features of a Chinese family with von Hippel-Lindau (VHL) disease revealed by bilateral pheochromocytoma. METHODS: The proband and other members in a Chinese family with familial pheochromocytoma were clinically evaluated and followed up. Genomic DNA extracted from the peripheral blood of 8 family members (including 3 patients) was amplified by polymerase chain reaction (PCR) and the PCR products were directly sequenced. RESULTS: The first presentation in the proband, his mother, and his sister was bilateral pheochromocytoma, and the missense mutation of 695G-A (Arg161Gln) in exon 3 of VHL gene was detected in the three patients. In the follow-up study, the proband and his mother were found to have other VHL tumors, induding retinal and cerebellar hemangioblastomas and pancreatic tumor. Neither clinical presentation of VHL disease nor gene mutation was found in other family members. CONCLUSION: VHL disease should be suspected in some patients with familial pheochromocytoma, and VHL gene screening helps to achieve early diagnosis of the disease.
