GroupAgeRange: 33.8Y +/- 17.6Y

GroupInfo: Clinical characteristics of 258 patients from 80 unrelated Chinese families were reported in this study. Grouped by the 21 mutations found, 3 families with 13 members total were described. it is unclear how many distinct families are reported in group 6B. 9 individuals were described. Phenotypic information was given for this mutation.

GroupHPOFreeText: 7 of the 9 members presented with CNS hemangioblastoma (mean age of 29.9Y), 2/9 had retinal angiomas at 25Y and 35Y, 1 had renal cell carcinoma (at 30Y), pancreatic cysts in 2 members (with an age of onset of 30 and 31Y), and 1 member with a genital system tumor (epididymis or broad ligament) at 24Y

CasePresentingHPOs: HP:0006880; HP:0002894; HP:0005584 (Cerebellar Hemangioblastoma; neoplasm of the pancreas; renal cell carcinoma)

CaseHPOFreeText: At 35-year old, the female patient was diagnosed with VHL due to clinical presentation of pancreatic serous cystic neoplasm and renal cell carcinoma, and cerebellar hemangioblastomas that were surgically removed at age 21. The patient had underwent total pancreatectomy and right nephrectomy for pancreatic serous cystic neoplasm (SCN) and renal cell carcinoma (RCC), respectively. 4 years later, tumors in the liver were detected by CT scan and radiographically diagnosed as metasta-ses of the pancreatic SCN or RCC. Again, morphology and immunohistochemical findings of the resected tumors again were similar to the primary pancreatic SCN, thus diagnosed as multiple metachronous liver metastases of pancreatic SCN. As of 47Y, the patient has remained disease-free without any recurrence after the third operation.

Case: M, 30Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband (patient 23) had three family members genetically confirmed with the mutation: his son/ patient 61 (asymptomatic at time of assessment), his daughter/ patient 62 (asymptomatic at time of assessment), and his cousin/ the son of his Aunt 3/ patient 68 (CNS hemangioblastoma at 26). The proband also had 5 family members who passed away before they could be confirmed with the mutation: his father/patient 63 (CNS hemangioblastoma at 35, retinal angioma at 35); his sister/ patient 64 (CNS hemangioblastoma at 24 and multiple pancreatic cysts/tumors at 31); his aunt 1/ patient 65 had a CNS hemangioblastoma at 35; his aunt 2/ patient 66 had a CNS hemangioblastoma at 20; and his aunt 3/ patient 67 had a CNS hemangioblastoma at 44.
