    1. Of the 13 individuals tested, V:2, IV:4, IV:6, III:2, III:3, and III:11 were all found to carry the P25L mutation in the VHL gene.

      PatientID: III:2

      KindredID: 1

      Case: F, 62, Ethnicity Unknown

      DiseaseAssertion: Asymptomatic

      FamilyInfo: The patient's father (II:3) had a brain tumour at age 53 and died at age 78. The patient's paternal aunt (II:1) died of stomach cancer at age 80. The patient's paternal grandfather died at age 50 due to a brain tumour. The patient had three children all of whom carried the P25L mutation and were asymptomatic (IV:4 and IV:6) except patient IV:2 who presented with a retinal hemangioma and renal cyst. Her daughter (IV:2) had three children and one was found to carry the mutation. The patient had seven siblings, five of whom underwent genetic testing. Two were found to carry the mutation but both were asymptomatic (patient III:3 and III:11). Patient III:3 had six children one of whom died due to clear cell renal carcinoma at age 48 but did not carry the P25L mutation. Of the 13 family members tested, V:2, IV:4, IV:6, III:3, and III:11 were all found to carry the P25L mutation in the VHL gene. Refer to Figure 1 for pedigree.

    1. DNA obtained from peripheral blood was available for all patients but only patient RCC-23, with a p.P25L alteration, showed in the germline the same aminoacidic change detected in tumor tissue.

    1. Case 3 (intradural tumor of T7 spinal nerve roots), which was first thought to be sporadic (non-familial) in 2001, was then re-classified as “HB-only VHLD” (form fruste of VHLD) after the patient’s sister, aged 53, was diagnosed with cerebellar HB (in the sister a germline point mutation and 2 somatic point mutations were found in the DNA of the cerebellar HB, and the case was included as case HB-25 in another study [28]). To the best of our knowledge, this is the first case of a patient with “HB-only VHLD” having clinical expression outside CNS.

      FamilyInfo: Sister was thought to be sporadic (non familial) in 2001 with a spinal T7 tumor - genetic testing in this paper describes her (the sister, case 3) without any mutations.

      CasePresentingHPOs: HP:0006880 (cerebellar hemangioblastoma)

      CaseHPOFreeText: The patient had a single cerebellar hemangioblastoma that was diagnosed at age 53. She had a germline point and 2 somatic point mutations found in the DNA of her CHB. These mutations are discussed further in PMID: 24335534
