KindredID: 18

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.

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).

Case: M, 38Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: Patient’s mother (I:1) was found with the same mutation and RCC at 63Y. The proband’s brother (II:1) died before diagnosis; thus no DNA sample available. He presented with hemangioblastoma at 19Y

CasePresentingHPOs: HP:0010797; HP:0009711 (hemangioblastoma, retinal capillary hemangioma)

Case: F, 27Y0M, Hungarian

DiseaseAssertion: VHL

FamilyInfo: The patient had an affected brother (IV-14) who carried the Ser80Asn mutation and presented with pheochromocytoma and retina hemangioblastoma. The patient's mother (III-7) carried the same mutation and had a brain hemangioblastoma and retina hemangioblastoma. The uncle (III-8) harboured the same mutation and had brain hemangioblastoma, pheochromocytoma, and retina hemangioblastoma. He had three kids, out of which only one carried the mutation but was asymptomatic (IV-16). The patient's grandmother (II-5) also harboured the same mutation and presented with renal cell carcinoma. This patient's great aunt (II-1) carried two different VHL mutations; the Ser80Asn and Pro25Leu but herself was asymptomatic. She passed the Ser80Asn mutation to her daughter, the proband (III-1), who had renal cell carcinoma, brain hemangioblastoma, and pheochromocytoma. Refer to figure 1 for pedigree.

CasePresentingHPOs: HP:0010797, HP:0009711, HP:0000107 (hemangioblastoma, retinal capillary hemangioma, renal cyst)

CaseHPOFreeText: The patient presented with brain hemangioblastoma at age 22, retina hemangioblastoma at age 23, and renal cysts at age 20.
