KindredID: 1

Case: F, 32Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: Her paternal grandfather (I:1) had been diagnosed with an adrenal tumor and hypertension in his 40s. In addition, four other relatives developed unilateral PHEOs: her father (II:1) at age 73, her 34-year-old brother (III:2), her paternal aunt in her 40s (II:4), and the aunt’s 12-year-old son (III:7). Subsequently, the son of III.7 (IV:3) was also diagnosed with PHEOs at 23 years of age. All affected individuals underwent adrenalectomy and remain asymptomatic, 1 to 30 years after surgery. In addition, a renal cyst was detected in individual III.2 at the time of the PHEO diagnosis, whereas II.1 developed multiple spinal cord hemangioblastomas after the adrenal tumor resection. No RCCs were diagnosed. Other declared diseases in this family are: thyroid nodule and bladder carcinoma but the presenting patient is unclear.

CohortInfo: Patients with the diagnosis of familial or sporadic PHEO and their relatives.

CasePresentingHPOs: HP:0002666 (Pheochromocytoma)

CaseHPOFreeText: Diagnosed with a normetanephrine-secreting, 5-cm right PHEO with no other clinical features of VHL disease.

DiseaseAssertion: VHL

FamilyInfo: Her two sons and her father had the same VHL mutation.

CohortInfo:Three patients with endolymphatic sac tumors were studied.

CasePresentingHPOs: HP:0001737, HP:0002666, HP:0030393, HP:0009713 (pancreatic cysts, pheochromocytoma, endolymphatic sac tumor, spinal hemangioblastoma)

CaseHPOFreeText: She presented with pancreatic cysts and pheochromocytoma at age 32. She experienced headache and dizziness and a temporal bone mass consistent with an ELS tumor was found on brain MR imaging. A preoperative audiogram showed no hearing function and she underwent a left transcochlear approach and resection of the tumor. The pathological diagnosis was consistent with an ELS tumor. She was later found to have a spinal hemangioblastoma that was resected and included in this study.

FamilyInfo: There was said to be, at the time, no affected relatives

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

CasePresentingHPOs: HP:0006748; HP:0002668; HP:0006476; HP:0006880; HP:0009711; HP:0000618; HP:0010797 (adrenal pheochorocytoma, paraganglioma, abnormality of the pancreatic islet cells, cerebellar hemangioblastoma, retinal capillary hemangioblastoma, blindness, hemangioblastoma)

CaseHPOFreeText: At 8Y, (in 1978), she was operated for a right pheochromocytoma; at age 13 for a contralateral pheochromocytoma; at age 15, for a 4-cm mass at the neck was diagnosed by selective arteriography as a carotid paraganglioma. The patient was then operated twice for cerebellar hemangioblastoma at age 22, leading to the diagnosis of VHL disease. At age 27, the patient was operated again for a retrocaval pheochromocytoma and for islet cell tumors. The patient was also repeatedly treated for bilateral retinal hemangioblastomas leading to blindness at age 32. At age 36, again a pheochromocytoma was removed
