PatientID: 7

KindredID: 3

Case: F, 18Y0M, Indian

DiseaseAssertion: VHL

FamilyInfo: Another member of this family (Gen 1) presented with the same mutation and bilateral pheochromocytoma, pancreatic cysts, RCC and neural hemangioblastoma.

CohortInfo: This retrospective study was conducted at Department of Endocrinology of a tertiary care health centre in Western India. Patients presented to our institute between 2008 and 2016 were included in the study. During the study period a total of 33 patients were suspected to have VHL syndrome based on clinical features among whom 31 patients were found to have mutation in VHL gene. All patients are of Asian Indian descent.

Case: F, 26Y0M, Ethnicity Unknown

DiseaseAssertion: assumed VHL

FamilyInfo: Positive family history of VHL.

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

CasePresentingHPOs: HP:0000618; HP:0009711; HP:0010797; HP:0002668 (blindness, retinal capillary hemangioma, hemangioblastoma, paraganglioma)

CaseHPOFreeText: At 15Y she presented with loss of visual acuity, leading to the diagnosis of bilateral retinal hemangioblastomas (treated with laser and cryotherapy), with the outcome of unilateral blindness. The patient was then operated 3 times for CNS hemangioblastomas between ages 18 and 24. At age 26, she presented with a palpable lateral neck mass. CT of the head and neck revealed a 3-cm carotid body tumor (paraganglioma).
