PatientID: 12

KindredID: 12

Case: F, 36Y0M, Ethnicity Unknown

DiseaseAssertion: assumed VHL

FamilyInfo: 3/4 of her sons also carried the mutation, one of which presented with a paraganglioma.

CohortInfo: An international consortium registered patients with head and neck paragangliomas with VHL or RET gene mutations.

CasePresentingHPOs: HP:0002668; HP:0006748; HP:0002886 (paraganglioma, adrenal pheochromocytoma, vagal paraganglioma)

CaseHPOFreeText: At 39Y (in 1993), she presented with recent onset of hypertension and was diagnosed with a right pheochromocytoma. (At age 36, a suspected left pheochromocytoma was noted by CT and confirmed at age 39 by [123I]MIBG scintigraphy). This imaging showed in addition an uptake located in the neck. MRI confirmed a left adrenal tumor and a left 2-cm vagal paraganglioma that was removed and confirmed histopathologically.

CaseNotHPOs: N/A

CaseNotHPOFreeText: No other tumor of the VHL spectrum was discovered.

Case: F, 39Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband, patient 72, has multiple family members with the same mutation. Her father (patient 73) had a CNS hemangioblastoma at 65, renal cell carcinioma at 54, and multiple pancreatic cysts/tumors at 67. Her sister 2 (second sister) had multiple pancreatic cysts/tumors at 36, and a CNS hemangioblastoma at 39. Her sister 3 had multiple pancreatic cysts/tumors at 32, and a retinal angioma at 34. The proband's sister 1 had a CNS hemangioblastoma at 22, but passed away before they could be diagnosed/ confirmed with the mutation.

CasePresentingHPOs: HP:0010797; HP:0005584; HP:0001732; HP:0001737; HP:0002666 (Hemangioblastoma, Renal cell carcinoma, Abnormality of the pancreas, Pancreatic cysts, Pheochromocytoma)

CaseHPOFreeText: The patient presented with a CNS hemangioblastoma, renal cell carcinoma, and multiple pancreatic cysts/tumors at 37, and a pheochromocytoma at 39.
