Direct sequencing and multiplex ligation dependent probe amplification were performed on thirteen unrelated subjects with VHL mutations. The clinical manifestations and family histories of the subjects were evaluated. A 21 year old Korean female patient presented with pheochromocytoma at age 24 and multiple pancreatic lesions at age 21. Genetic testing confirmed a familial frameshift mutation at c.592delC of the VHL gene. The patient has a mother who presented with pheochromocytoma at age 27, multiple pancreatic lesions at age 48, and developmental venous anomaly or meningioma.
