Case: F, 50Y0M, 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.

CaseHPOFreeText: This patient presented with CNS hemangioblastoma (25Y), retinal angioma (16Y) and pancreatic tumors or cysts (undefined) (22Y).

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).

DiseaseAssertion: VHL

FamilyInfo: Patient’s grandfather (I-1), now deceased, and aunt (II-1) had CNS/spinal hemangioblastoma and the confirmed VHL gene mutation. Her mom II-2 had confirmed VHL and CNS hemangioblastoma; and her cousin (III-6) has renal cell carcinoma and CNS/spinal hemangioblastoma and also the confirmed VHL gene mutation. Her uncle (II-3) has confirmed VHL gene and pancreatic and renal cysts. Her brother and sister (III-3; III-4) both were found with the confirmed VHL gene mutation; III-3 with retinal hemangioblastoma and CNS/spinal hemangioblastomas and III-4 with pancreatic and ovarian cysts. IV-1 and IV-3, were confirmed with the VHL gene mutation although no other manifestations.
