CaseHPOFreeText: Was diagnosed with bilateral pheochromocytoma resected when she was the age of 18 years. She presented several relapses, the most recent one at the age of 32, when she was also diagnosed with cerebral angioma.

Case: F, 52Y0M, Ethnicity Unknown

DiseaseAssertion: Assumed 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:0010797; HP:0002666 (Hemangioblastoma, Pheochromocytoma)

CaseHPOFreeText: This patient presented with CNS hemangioblastoma (18Y) and pheochromocytoma (17Y).

VariantEvidence: Authors state that the c.712C>T germline familial variant of the VHL gene in this patient is “inferred from the family”. No genetic testing was done on this patient to confirm this. Being that this familial 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).
