CasePreviousTesting:

GenotypingMethod: Genetic analysis was performed at the laboratory of hematology of the Radboud University Medical Center in Nijmegen. Ion semiconductor sequencing (Ion-Torrent) was used to analyze the VWF gene from peripheral blood obtained in EDTA tubes or from saliva samples. The 52 exons of VWF gene were analyzed including ±20 bp exon-intron boundaries. If no VWF gene variant was detected, multiplex ligation-dependent probe amplification (MLPA) analysis was performed to find large deletions or duplications. Thus, MLPA was performed in 183 patients (46.9%). All variants were confirmed with Sanger sequencing.

DiseaseAssertion: VHL

FamilyInfo: Families were selected based on their clinical data and family history. Patient’s father (BI1) had pheochromocytoma, but was not genetically tested. The patient’s son (BIII3) developed pheochromocytoma at the age of one, but progressed to bilateral pheochromocytoma 3 years later. Genetic testing revealed the same mutation in the patient and his son. In fact, a sample of amniotic fluid was taken from the patient’s wife (BII2) during the 16th week of pregnancy for prenatal testing, which was later confirmed to be the same point mutation as BII2. See pedigree in figure 1.

CaseHPOFreeText: The first symptoms of pheochromocytoma appeared in the patient at age 40Y0M.
