      GroupInfo: This family group of 1 individual has clinically confirmed VHL disease presenting with retinal angiomatosis. This individual was found to harbor a c.278G>T variant causing a Gly93Val missense mutation (noted in the paper as c.491G>T due to Latif reference transcript being used).

      GroupHPOFreeText: Patients within this family were found to have a clinical diagnosis of VHL disease. No VHL clinical phenotypes were explicitly stated other than retinal angiomatosis.

    1. A previously healthy 10-year-old girl presented with occasional routine blood pressure measurements by her pediatrician above the 99th percentile for her age, sex, and height. She had noted mild hand edema over the previous days and reported recent nocturia. She was taking no medications. Family history was unremarkable. The physical examination was without significant findings other than an elevated blood pressure of 139/113 mm Hg. Urine tests showed boderline moderate albuminuria (albumin-creatinine ratio of 50 mg/g). There was no hematuria.On ultrasound, kidney size and parenchyma were unremarkable but an increased flow rate of the left renal artery in color duplex sonography was detected (systolic flow rate: right, 100 cm/s; left, 300 cm/s [age-adjusted normal values range from 72 to 104 cm/s]) (Fig 1A and B). No additional finding was reported. Magnetic resonance (MR) angiography of the kidney vessels was performed (Fig 2A) and antihypertensive therapy was initiated.

      PatientID: N/A

      KindredID: 1

      Case: F, 10Y0M, Ethnicity Unknown

      DiseaseAssertion: Assumed VHL

      FamilyInfo: No family history, authors indicate that the variant occurred de novo.

      CaseHPOFreeText: Patient presented with occasional high routine blood pressure at 10Y0M. She noted mild hand edema over the past days and reported recent nocturia. Physical examination appeared normal other than elevated blood pressure of 139/113 mm Hg. Urine tests showed moderate albuminuria (albumin-creatinine ratio of 50 mg/g), as well as high levels of noradrenaline and normetanephrine, suggestive of benign pheochromocytoma. Ultrasound showed normal kidney size and parenchyma, but color duplex sonography revealed increased flow rate of the left renal artery. This finding suggests renal artery stenosis. Magnetic Resonance Angiography of the kidney vessels showed a solid tumor that had cystic features. Tumor resection normalized blood pressure and pathologic examination of the removed tumor confirmed pheochromocytoma. Patient was diagnosed with secondary hypertension due to compression of renal vessels and catecholamine production by vHL-associated pheochromocytoma. Antihypertensive therapy with phenoxybenzamine as α blockade was initiated, along with subsequent expansion of the therapy with a β-blocker. Authors mention that the patient is in complete remission with no other manifestations of VHL disease and is receiving close follow-up.

      PatientID: None

      KindredID: 1

      Case: F, 17Y0M, Ethnicity Unknown

      DiseaseAssertion: Retinal hemangioblastoma

      FamilyInfo: The heterozygous missense variant NM_000551.3:c.311G>T was identified on her 21-year-old sister and her mother, but not her father. The sister had hypertension and a paraganglioma. The patient’s mother had refused a complete staging.

      CasePresentingHPOs:HP:0009711 (Retinal hemangioblastoma)

      CaseHPOFreeText: The patient’s evaluation was normal with the exception of a small retinal hemangioblastoma.
