KindredID: 6

Case: 30Y0M, Sex unknown, Chinese

DiseaseAssertion: VHL

FamilyInfo: Their sister had the same deletion and presented with VHL disease type 1, and first presented with a CNS hemangioblastoma at age 21. A second sister had no mutation and was asymptomatic, and the proband's daughter had the same deletion, but was asymptomatic at the time of the study.

GroupInfo: Clinical characteristics of 258 patients from 80 unrelated Chinese families were reported in this study. Grouped by the 21 mutations found, 3 families with 13 members total were described. it is unclear how many distinct families are reported in group 6B. 9 individuals were described. Phenotypic information was given for this mutation.
