PatientID: II-4

KindredID: 3

Case: M, 38Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The patient's mother (I-2) died as a result of pancreatic cancer. The eldest sister of the patient (II-1) underwent surgery for a brain tumor and had pancreatic and renal cysts. Another sister (II-2) underwent surgery for breast cancer. The patient's two sons (III-6 and III-7) were found to harbour their father's VHL mutation. See Figure 3 for family pedigree.

CasePresentingHPOs: HP:0006770, HP:0001737, HP:0009713, HP:0000107, HP:0000787 (clear cell renal cell carcinoma, pancreatic cysts, spinal hemangioblastoma, renal cysts, nephrolithiasis)

CaseHPOFreeText: The patient was treated for kidney stones at age 33. At age 38 he was found to have a mass in the right kidney. Upper abdominal CT revealed the presence of multiple nodules and lumpy low-density areas in the left and right kidneys with uneven density. Multiple round low-density lesions were observed in the left and right kidneys, and in the pancreas. Brain CT revealed no abnormalities, but sphenoiditis was observed on the right side. Thoracic MRI revealed a round-shaped mixed signal (diameter, 12.0 mm) in the sixth thoracic vertebra. Contrast-enhanced scanning revealed minor enhancement, which appeared to indicate the presence of a hemangioma. Postoperative pathological analysis confirmed that the tumor was a clear cell renal cell carcinoma.

Case: F, 38Y0M, Hungarian

DiseaseAssertion: VHL

FamilyInfo: Family C consists of two parents and their two daughters. Patient's 14 year old daughter (see patient 4) shares the same mutation as him. She developed a retinal angioma at 12 years of age and a spinal cord hemangioma was detected at 14 years. The mother and the other daughter were free from any manifestations of the disease and showed no mutations in the VHL gene.

CasePresentingHPOs: HP:0009713; HP:0006880; HP:0009711; HP:0006770 (spinal hemangioblastoma, cerebellar hemangioblastoma, retinal capillary hemangioma, clear cell renal cell carcinoma)

CaseHPOFreeText: Radiological investigations detected bilateral kidney tumors, a cerebellar and a spinal cord hemangioma at 34 years of age. Histological analysis of the kidney verified RCC. Four years later (38 years of age), retinal angioma developed in both of his eyes.

Case: F, 38Y0M, German

DiseaseAssertion: VHL

FamilyInfo: N/A

CohortInfo:All patients from the German registry for VHL with PNETs >3 cm diameter with tumours located in the pancreatic body or tail region.

CasePresentingHPOs: HP:0009711, HP:0009713, HP:0006880, HP:0009726, HP:0030405, HP:0001737 (retinal capillary hemangioma, spinal hemangioblastoma, cerebellar hemangioblastoma, renal neoplasm, pancreatic endocrine tumour, pancreatic cysts)

CaseHPOFreeText: Retinal angiomatosis at age 17, hemangioblastoma of the cervical spinal cord at age 24, cerebellar hemangioblastoma at age 27, left renal tumor at age 36. Pancreatic endocrine tumour and pancreatic cysts at age 38. She had a laparoscopy which found an 8-cm retrogastric cyst, 3.2-cm benign PNET, and a serous cystadenoma.
