Case: M, 36Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband's mother and sister both presented with renal cell carcinoma at ages 49 and 27, respectively. Their mother also had a CNS hemangioblastoma at 45, and their sister had a retinal angioma at 30. No genotyping information was available for either family member.

CasePresentingHPOs: HP:0005584; HP:0002666 (Renal cell carcinoma, Pheochromocytoma)

CaseHPOFreeText: The proband presented with renal cell carcinoma at age 22, and a pheochromocytoma at age 36.

Case: F, 80Y0M, 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.

CaseHPOFreeText: This patient presented with CNS hemangioblastoma (36Y), pheochromocytoma (36Y) and retinal angioma (22Y).

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).
