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).

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)

CaseHPOFreeText: This patient presented with retinal angioma (18Y) and pheochromocytoma (20Y). Age of diagnosis of CNS hemangioblastoma and renal cell carcinoma is unknown.

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).
