PatientID: None (Cousin 1)

KindredID: G

Case: Sex Unknown, 37Y0M, Hungarian

DiseaseAssertion: Assumed VHL

FamilyInfo: Large VHL family spanning five generations. The index patient presented with pheochromocytoma, renal cell carcinoma as well as spinal cord, cerebellar, and medulla oblongata hemangioblastomas. Her parents showed no clinical, biochemical, or radiological evidence of the disease, but VHL-associated tumors were detected in five other family members (bilateral renal cell carcinomas in one, renal cysts in one, spinal cord, cerebellar, and medulla oblongata hemangioblastomas in three, retinal hemangioblastomas in four, and pheochromocytomas in two family members).

CasePresentingHPOs: HP:0010797; HP:0009711 (Hemangioblastoma, Retinal capillary hemangioma)

CaseHPOFreeText: Presented with CNS hemangioblastoma at age 37 and retinal hemangioblastoma at age 18. No VHL diagnosis noted but assumed to have VHL based on genetic, clinical and familial findings.

VariantEvidence: Patient data is extracted from two rows assumed to be referring to the same patient (i.e. tumor samples 40 and 41 in Supplementary Table 1a). Carbonic anhydrase 9 (CA9) mRNA level of 795.70 (PCC) and 815.38 (PCC) were detected. Membrane CA9 immunostaining was observed in both PCC samples.
