Abstract
Von Hippel-Lindau (VHL) disease is an autosomal dominant inherited tumor syndrome associated with germline mutations in the VHL gene. VHL disease, as well as several other cancer syndromes, has been associated with an increased risk of pheochromocytomas, which are catecholamine-secreting tumors of the adrenal gland. VHL disease genotype-phenotype correlations have been well established based on the type of mutations in the VHL gene. However, although many groups have reported VHL germline mutations in different countries, no previous report has described VHL gene mutations in VHL disease and/or pheochromocytoma patients in Korea. In this study, we used direct sequencing to investigate VHL germline mutations in Korean patients with VHL disease or pheochromocytomas (11 VHL patients and 3 additional members from 7 families, 2 patients from 1 family with familial pheochromocytoma, and 2 cases of isolated pheochromocytoma). We found a total of 7 VHL germline mutations (6 missense and 1 frameshift), 3 of which were novel (323_324delGC, 355T>C and 361G>A). No VHL germline mutation was found in the 2 patients with isolated pheochromocytomas and paragangliomas. This study provides informative data for VHL germline mutations and VHL-related phenotypes in Korea.
