PatientID: Carrier 1 (sister to proband 1)

KindredID: 1

Case: F, 29Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The family with PCCs includes 56 members of 4 generations, and is from Gansu Province. Among them, 7 extended over 3 generations were diagnosed as PCCs. One died before admission and another died due to a cardiovascular incident. Five were initially evaluated; evaluation included medical history, physical examination, abdominal ultrasonography, CT or MRI and laboratory tests. All 5 probands of this family underwent surgical resection. The tumors were benign under pathological examinations. There were no recurrence and malignant transformation over the period of up to 23-year follow-up. Twenty members, including 5 live patients and 15 direct relatives, accepted genetic examination.

CasePresentingHPOs: HP:0002666 (Pheochromocytoma)

CaseHPOFreeText: Bilateral PCC diagnosed at 17Y and did not have any other clinical presentations. Stated as having VHL type IIC.

Case: M, 49Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband's mother and sister had a CNS hemangioblastoma at ages 40 and 50, respectively. His nephew presented with a CNS hemangioblastoma (age 15), a retinal angioma (age 27), and renal cell carcinoma (age 25). His daughter had a retinal angioma at age 14, and a CNS hemangioblastoma at age 24. No genetic testing information was available for family members.
