Case: M, 52Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband's son and sister were both confirmed to have this VHL mutation. Their son had a retinal angioma at 26 and a pheochromocytoma at 31. Their sister had a pheochromocytoma at 14. Their mother had renal cell carcinoma at 56, however no genotyping information is available for her.

Case: M, 52Y0M, Indian

DiseaseAssertion: VHL

FamilyInfo: Another member of this family (Gen 1) presented with the same mutation and bilateral pheochromocytoma.

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, 52Y0M, Chinese

DiseaseAssertion: Assumed VHL

FamilyInfo: Eight affected individuals in the patient’s family were retrospectively identified by reviewing medical records and from the recall of relatives. Three had passed away before 40 years of age because of central nervous system hemangioblastoma. Among the 10 living family members that carried the same NM_000551.3:c.326_339dupTCCACAGCTACCGA the patient carried, 3 had renal cysts and 1 had developed renal cell carcinoma, 2 had central nervous system hemangioblastoma, 1 had retinal hemangioblastomas, 1 was diagnosed with glioblastoma, and 5 were asymptomatic.
