Case: F, 69Y0M, Arab

DiseaseAssertion: VHL

FamilyInfo: No family history of VHL disease was described for this patient. Immediate family members were recommended to genetically test for the relevant variant or monitor for VHL-related symptoms.

CasePresentingHPOs: HP:0006770; HP:0006880; HP:0009713; HP:0000107; HP:0001737 (clear cell renal cell carcinoma; cerebellar hemangioblastoma; spinal hemangioblastoma; renal cyst; pancreatic cysts)

CaseHPOFreeText: At 63Y, Patient 3 had a left radical nephrectomy for renal cell carcinoma. She also had multiple pancreatic and right renal cysts. At 67Y, Patient 3 exhibited cerebellar and spinal hemangioblastomas, renal cell carcinoma, and cysts in kidneys and pancreas. She was diagnosed with VHL disease. Two years later, had a right radical nephrectomy for renal cell carcinoma. Her entire pancreas was covered with cysts (see table 1).

CaseNotHPOs: HP:0002088; HP:0001392; HP:0005264; HP:0001743 (abnormal lung morphology; abnormality of the liver; abnormality of the gallbladder; abnormality of the spleen)

CaseNotHPOFreeText: No lesions were observed in the lungs, liver, gallbladder, and spleen.

Case: M, 58Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband, patient 23, had a brother (patient 24) and father (patient 25) who were both genetically confirmed with the mutation. The brother presented with a CNS hemangioblastoma, renal cell carcinoma, and pancreatic cysts/tumors at age 32. The father presented with renal cell carcinoma and pancreatic cysts/tumors at age 58.

CaseHPOFreeText: The proband's father, patient 25, presented with renal cell carcinoma and multiple pancreatic cysts/tumors.

Case: F, 69Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband (patient 138) had multiple family members affected with the mutation. Their daughter (pt 139) was asymptomatic at the time of assessment; their son (pt 140) was also asymptomatic at the time of assessment; their mother (pt 141) presented with a CNS hemangioblastoma at 66, renal cell carcinoma at 69, and multiple pancreatic cysts/tumors at 66; their sister 1 (pt 142) presented with a CNS hemangioblastoma at 32, renal cell carcinoma at 36, and multiple pancreatic cysts/tumors at 36; the son of sister 1 was asymptomatic at the time of analysis; the daughter of sister 1 was asymptomatic at the time of analysis; the proband's sister 2 presented at age 39 with CNS hemangioblastoma, renal cell carcinoma, and multiple pancreatic cysts/tumors; and the son of sister 2 was asymptomatic at the time of analysis. All members of this family were genetically confirmed to have this mutation.
