    1. The proband, a 52-year-old Iranian man, was recognized with VHL.

      PatientID: III-16 (proband)

      KindredID: 1

      Case: M, 52Y0M, Iranian

      DiseaseAssertion: VHL

      FamilyInfo: Familial history was positive for BL-PCC in his son and his daughters, and for retinal hemangioblastoma and bilateral pheochromocytoma in his siblings. A total of 43 members of the kindred, 24 males and 19 females, aged 2-77 years were reached for evaluation. It is stated in the paper that all affected subjects (13) were positive for the same mutation (c.500G>A). Additionally, gene sequencing revealed that 4 asymptomatic members of the kindred also harbored the pathogenic mutation.

      CasePresentingHPOs: HP:0002666; HP:0006880 (Pheochromocytoma; cerebellar hemangioblastoma)

      CaseHPOFreeText: Patient had bilateral pheochromocytoma diagnosed at 30Y which had been operated on surgically at 50Y. He was hospitalized at age 50Y also for headache, vertigo, and gait problems for the past 2 months. Brain MRI then showed a huge lobulated hyper-intense lesion measuring 48 by 38 by 28 mm in the right cerebellar hemisphere with significant projection into the fourth ventricle, consistent with hemangioblastoma of reticular pattern.

      CaseNotHPOs: HP:0000077 (abnormality of the kidney)

      CaseNotHPOFreeText: There was no case of kidney tumors among the kindred.

      Case: F, 25Y0M, Iranian

      DiseaseAssertion: assumed VHL

      FamilyInfo: Familial history was positive. See Fig 1. A total of 43 members of the kindred, 24 males and 19 females, aged 2-77 years were reached for evaluation. It is stated in the paper that all affected subjects (13) were positive for the same mutation (c.500G>A). Additionally, gene sequencing revealed that 4 asymptomatic members of the kindred also harbored the pathogenic mutation. Phenotypes include pheochromocytoma, hemangioblastoma, and retinal HB.

      CasePresentingHPOs: HP:0002666; HP:0006880 (Pheochromocytoma, cerebellar hemangiomblastoma)

      CaseHPOFreeText: Patient had a unilateral PCC and cerebellar HB at 23Y which was surgically removed at the time. She presently has no abnormal findings.

    1. All family members underwent clinical, laboratory, imaging, and genetic evaluation.

      PatientID: IV-28 [written in Table 2 as IV-24 - typo]

      KindredID: 1

      Case: F, 33Y0M, Iranian

      DiseaseAssertion: assumed VHL

      FamilyInfo: Familial history was positive. See Fig 1. A total of 43 members of the kindred, 24 males and 19 females, aged 2-77 years were reached for evaluation. It is stated in the paper that all affected subjects (13) were positive for the same mutation (c.500G>A). Additionally, gene sequencing revealed that 4 asymptomatic members of the kindred also harbored the pathogenic mutation, one of which was this patient who proved to be symptomatic. Phenotypes include pheochromocytoma, hemangioblastoma, and retinal HB.

      CasePresentingHPOs: HP:0011732; HP:0006880; HP:0010302 (abnormality of adrenal morphology, cerebellar hemangioblastoma, spinal cord tumor)

      CaseHPOFreeText: Originally thought to be an asymptomatic carrier, however after follow-up was found to be symptomatic: brain MRI revealed multiple tutors, including a frontal mass (cerebellar tumor) with multiple spinal lesions, and an abdominal CT showed a 1.6x1.7 right adrenal mass. Additionally, this patient was pregnant at the time, to which was terminated at the 38th week of gestation with a caesarian section. She has two other children already.
