Case: M, 12Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband (patient 42) had four family members confirmed with the mutation: his son (CNS hemangioblastoma at 12, retinal angioma at 11); his sister 1 (patient 116) presented with multiple pancreatic cysts/tumors at 53; his niece (daughter of sister 2) was asymptomatic at the time of assessment, and his nephew (son of brother 2) presented with a CNS hemangioblastoma at 12, and pheochromocytoma and multiple pancreatic cysts/tumors at 18. The proband also had three family members who passed away before diagnosis/ before they could be confirmed with the mutation: his sister 2 (patient 117) had multiple pancreatic cysts/tumors at 46, his brother 1 presented with a CNS hemangioblastoma at 47, renal cell carcinoma at 59, and multiple pancreatic cysts/tumors at 59; and his brother 2 presented with a retinal capillary hemangioma at 43, and CNS hemangioblastoma, renal cell carcinoma, and multiple pancreatic cysts/tumors at 44.

Case: F, 53Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: Positive. The patient's sibling was the proband and had the mutation c.349T>G presenting with renal cell carcinoma, retinal angioma, hemangioblastoma, abnormality of the pancreas, and epididymal or ovarian cystadenoma.The patient's mother, aunt, grandmother, brother 1 and 2, and sister 3 all passed before they could undergo genetic testing but had a variety of VHL presentations. The patient's third nephew were confirmed to have this genetic mutation. The nephew had hemangioblastoma and retinal angioma at age 13. Additional familial phenotypes can be found in Table 1.

CasePresentingHPOs: HP:0001732 (abnormality of the pancreas)

CaseHPOFreeText: The patient presented with abnormality of the pancreas at age 53.

Case: Sex Unknown, 44Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: Positive. Patient's son who was confirmed to have this mutation presented with hemangioblastoma at age 12. The patient's mother, aunt, grandmother, brother 1 and 2, and sister 3 all passed before they could undergo genetic testing but had a variety of VHL presentations. The patient's first sister and third nephew were confirmed to have this genetic mutation. The first sister presented with abnormality of the pancreas at age 53.
