Case: Sex Unknown, 39Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: Positive. Patient's mother did not undergo genetic testing but had a hemangioblastoma at age 50 and a pancreatic cyst or tumour at age 62. The patient's sister also had this mutation but was asymptomatic. Another one of the patient's sisters presented with hemangioblastoma (age 40), renal cell carcinoma (age 43), and pancreatic cysts or tumours (age 43). This patient died before diagnosis. The proband's brother also died before diagnosis and presented with hemangioblastoma and retinal angioma at age 27.

CaseHPOFreeText: The patient presented with hemangioblastoma at age 35. At age 37 she presented with retinal angioma and pancreatic cysts or tumours. At age 39 she presented with renal cell carcinoma.

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.

Case: F, 43Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: a 3 generational family found with 5 phenotypically affected members, two of which were confirmed with the exon 1 deletion. This patient and her son were tested to be found with the deletion of exon 1. Her son was found with retinal angiomas at 17Y, pancreatic cysts and epididymal/ovarian cystadenoma at 19Y, and hemangioblastomas at 23Y. Her two sisters and father all had hemangioblastomas; and father also had RCC, however the father and one sister were deceased; and the other sister was not available to provide a DNA sample.
