PatientsThe Chinese family study included five-generations comprising of 38 living family members, of whom nine were affected [Figure 1]. All living members were examined clinically. The clinical and radiographic images were published with the consent of the patient. The study was approved by the research Ethics Committees of Xi’an Jiaotong University School of Medicine. Written informed consents were obtained from all participants.Open in a separate windowFigure 1Haplotypes of the Chinese family affected by Von Hippel-Lindau (VHL). The open and filled blackened symbols indicated unaffected and affected individuals, respectively. The squares and circles symbolized the males and females, respectively. The proband, IV-3, was indicated by an arrow. The haplotyping was conducted using three polymorphic microsatellite markers. The marker order was determined from the Marshfield map and the UCSC Human Genome database (February 2009). The dark boxes symbolized haplotypes that cosegregated with the affected individuals and suggested linkage of VHL to disease in this family. The boxes with slash symbolized the dead family members.
PatientID: II:4
KindredID: 1
Case: F, Age Unknown (deceased), Chinese
DiseaseAssertion: VHL
FamilyInfo: A 5-generation family with VHL in 15 members. Both second generation children (presumed), 5 third generation, and 8 further generation individuals were affected and haplotyping was conducted using three polymorphic microsatellite markers. All of the 5th generation children (9 total at time of publication) had been sequenced and haplotyped as unaffected.
