PatientID: III-16 (proband)

KindredID: 1

Case: M, 52Y0M, Iranian

DiseaseAssertion: VHL

FamilyInfo: Familial history was positive for BL-PCC in his son and his daughters, and for retinal hemangioblastoma and bilateral pheochromocytoma in his siblings. A total of 43 members of the kindred, 24 males and 19 females, aged 2-77 years were reached for evaluation. It is stated in the paper that all affected subjects (13) were positive for the same mutation (c.500G>A). Additionally, gene sequencing revealed that 4 asymptomatic members of the kindred also harbored the pathogenic mutation.

CasePresentingHPOs: HP:0002666; HP:0006880 (Pheochromocytoma; cerebellar hemangioblastoma)

CaseHPOFreeText: Patient had bilateral pheochromocytoma diagnosed at 30Y which had been operated on surgically at 50Y. He was hospitalized at age 50Y also for headache, vertigo, and gait problems for the past 2 months. Brain MRI then showed a huge lobulated hyper-intense lesion measuring 48 by 38 by 28 mm in the right cerebellar hemisphere with significant projection into the fourth ventricle, consistent with hemangioblastoma of reticular pattern.

CaseNotHPOs: HP:0000077 (abnormality of the kidney)

CaseNotHPOFreeText: There was no case of kidney tumors among the kindred.

GroupInfo: Clinical characteristics of 258 patients from 80 unrelated Chinese families were reported in this study. Grouped by the 21 mutations found, 3 families with 15 members total were described, and phenotypic information was given for this group.

GroupHPOFreeText: 10 of the 15 members presented with CNS hemangioblastoma (mean age of 29.9Y), 2/15 had retinal capillary hemangiomas at 23Y and 30Y, renal cell carcinoma in 4 members (at a mean age of 41.5Y), pancreatic cysts in 5 members (with a mean age of onset of 41.4Y), and 1 member with pheochromocytoma at 38Y
