FamilyInfo: The patient's sister (the proband) had the same germline mutation, and presented with a CNS hemangioblastoma at 24, renal cell carcinoma at 32, and multiple pancreatic cysts/tumors at 33. The proband's mother had a CNS hemangioblastoma at 35, however no genotyping information is available for her.

Case: M, 20Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: This is the proband. 3 members of this family were found to have the mutation and pheochromocytoma. Other declared diseases in this family are: hemangioblastoma, parathyroid nodule, and esophageal carcinoma but the presenting patient is unclear. Relationship between these family members is unclear.

CohortInfo: Patients with the diagnosis of familial or sporadic PHEO and their relatives.

CasePresentingHPOs: HP:0002666 (Pheochromocytoma)

CaseHPOFreeText: Follow-up 25 years later but it is unclear if this pertained to all affected family members. Pheochromocytoma diagnosed at age 20. VHL type 2C.

Case: F, 62Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: 11 members of this family tested positive for the c.712C>T/c.499C>T germline variant of the VHL gene. 14 members of this family were assumed to carry this variant due to family history/personal medical history. Members of this family range from asymptomatic to multi-organ involvement (pheochromocytoma, pancreatic and renal cysts/tumors and hemangioblastomas). The family was previously reported in PMID 3942913.

CasePresentingHPOs: HP:0002666; HP:0009711; HP:0005584; HP:0010797 (Pheochromocytoma, Retinal capillary hemangioma, Renal cell carcinoma, Hemangioblastoma)

VariantEvidence: A point mutation (c.712C>T) was found. Being that this variant is out of bound with respect to the NM_000551.3 reference sequence, it was concluded that this variant is noted in the Latif et al. (1993) reference and was translated to c.499C>T (NM_000551.3).
