A retrospective cohort study included all the VHL patients diagnosed at Peking University First Hospital (Beijing, China) prior to June 1 2016. A total of 291 patients from 115 different families were included for analysis. This familial mutation (p.P97Afs*35, c.287_288insA) was confirmed in family #33, with 2 affected members that were both genetically confirmed for the mutation. A male proband (patient 99) was diagnosed with CNS hemangioblastoma at 37Y, retinal angioma at 20Y, renal cell carcinoma at 20Y, and multiple pancreatic cysts or tumours at 29Y. His brother (patient 100) was diagnosed with retinal angioma at 32Y, renal cell carcinoma at 43Y, and multiple pancreatic cysts or tumours at 43Y. This cohort was also published in a paper by Wang et al., 2018 (PMID: 29330336).
