    1. A female patient observed reduced vision in the right eye at age 17 years. She was diagnosed with retinal angiomatosis of the right eye. Laser therapy and brachytherapy were performed. Vision of the right eye remained reduced to 15%. At age 24, a hemangioblastoma of the cervical spinal cord was resected. At age 27, she underwent craniotomy for a cerebellar hemangioblastoma. Genetic testing revealed the mutation VHL c.394 C > T, which predict a truncated VHL protein (Q132X). In 2007, a 20 mm diameter left renal tumor was detected but not resected owing to its small size, as internationally recommended [1].In 2009 at age 38, abdominal MRI and CT angiography showed, in the axial view, a solid, 3.6 × 3.3 cm tumor of the pancreatic tail (Fig. 2a). Early arterial phase imaging after contrast injection revealed that the tumor had significant hyperperfusion. In addition, multiple pancreatic cysts were noted.

Pancreatic endocrine tumour and pancreatic cysts at age 38. She had a laparoscopy which found an 8-cm retrogastric cyst, 3.2-cm benign PNET, and a serous cystadenoma.

      Case: F, 80Y0M, Ethnicity Unknown

      DiseaseAssertion: Assumed 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: Authors state that the c.712C>T germline familial variant of the VHL gene in this patient is “inferred from the family”. No genetic testing was done on this patient to confirm this. Being that this familial 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).

    1. In Patient 1, who was 40 years old and had a cerebellar hemangioblastoma, the P86L missense heterozygous germline mutation was identified in exon 1. The DNA analysis of close relatives did not show affected subjects. This patient was recommended for VHL disease surveillance protocols (15) (Table 4) and developed a retinal hemangioblastoma 4 years after diagnosis.
