DiseaseAssertion: VHL

FamilyInfo: A family pedigree is provided in figure 1. Neither parent had VHL syndrome characterized by retinal capillary hemangiomas (RCHs). They likely did not undergo molecular testing because there was no mention of de novo status.

CaseHPOFreeText: A 32-year-old woman had been diagnosed in 2000 with multiple cerebellar and spinal hemangioblastomas. In 2005, she was examined at the eye clinic and were visual acuity was 20/20 and 20/25 in the right and left eye, respectively. No abnormalities were found in the right eye, but a peripheral RCH that was already partially treated with laser was observed in the left eye. Many tiny RCHs that surrounded the major lesion were also detected in this eye. Further laser treatments were scheduled, but the patient did not follow-up and instead came to the ophthalmic emergency service three years later. Visual acuity of the left eye worsened to 20/640, and she presented with retinal detachment. The partially treated RCH of the left eye worsened and and more tiny RCHs were detected. Cryotherapy was performed in the left eye but retinal detachment was still present at follow up. On follow up, no RCHs were detected in the right eye and vision loss developed in both eyes.

FamilyInfo: Large multigenerational family with a history of both VHL and spinocerebellar ataxia type 2 (SCA2). Screening for clinical and genetic diagnostics were gathered as well as thorough information on non-living members. His two daughters also appeared to have the VHL mutation. See family pedigree (Fig. 1).

CaseHPOFreeText: CNS (including retinal angiomas) and renal involvement; with cerebellum hemangioblastoma found at age 34Y. An oesophageal abnormality that was treated with vagotomy at age 35Y. At age 44Y had bilateral clear cell renal cancer resulting in a right partial nephrectomy and left total nephrectomy. Same year had spinal surgery to treat a syrinx associated with a spinal cord haemangioblastoma, as well as cystic lesions in the pancreas (consistent with epididymal cystadenoma).

CaseProblemVariantFreeText: c.477del, p.Glu160Serfs10 should be used. Details: 477del same as 475delA bc that codon is AAA so doesn't matter which A gets deleted: there is an A at 475 476 477 so for HGVS we say that 477 (the latter) is deleted since that follows HGVS nomenclature. Thus use c.477del: p.Glu160Serfs10

Case: Sex Unknown, 39Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: Positive. Patient's mother did not undergo genetic testing but had a hemangioblastoma at age 50 and a pancreatic cyst or tumour at age 62. The patient's sister also had this mutation but was asymptomatic. Another one of the patient's sisters presented with hemangioblastoma (age 40), renal cell carcinoma (age 43), and pancreatic cysts or tumours (age 43). This patient died before diagnosis. The proband's brother also died before diagnosis and presented with hemangioblastoma and retinal angioma at age 27.
