CohortInfo: The authors evaluated 64 VHL patients (32 women and 32 men) with renal involvement of whom 54/64 had undergone renal surgery or a radiofrequency thermal ablation procedure for RCC. In 10/64 VHL patients, at least one or more RCC were diagnosed, however at the time of diagnosis an indication for treatment was not yet present. For all patients several CT/MRI scans existed for retrospective description of tumour growth kinetics.

41 non-related patients with retinal capillary hemangioma presenting in the Benjamin Franklin University Eye Clinic between 1988 to 1999 Germany were evaluated for the presence of other VHL lesions. VHL disease was diagnosed in 33 patients based on the presence of other severe VHL lesions (spinal hemangioblastoma, cerebellar hemangioblastoma, renal cysts, pancreatic cyst, renal carcinoma, and pheochromocytoma), molecular genetic testing, and/or family history. VHL germline mutations were identified in 27 out of 29 VHL families screened with molecular genetics. Blood samples were genetically tested using PCR-SSCP sequencing. One patient with VHL-related retinal angiomatosis was found to have germline splicing mutation (c.464-1G>C) mutation in the VHL gene. This variant was reported as c.677-1G>C (AF010238.1) and mapped to c.464-1G>C (NM_000551.3).

540 patients from 187 unrelated Chinese VHL families at the Peking University First Hospital were all screened for VHL clinical features and germline mutations. Of these, clinical characteristics were observed in 258 patients from 80 unrelated Chinese families. These were reported in this study, grouped by the 21 mutations found. PCR and MLPA on peripheral blood detected the VHL mutations. Possessing the c.464-1G>C mutation, 11 members total from 2 families were described, and phenotypic information was given for this group. With ages of onset ranging from 10-66Y, hemangioblastomas were observed in 6/11 members, renal cell carcinoma in 4, pancreatic cysts in 4, and a papillary cystadenoma of the epididymis genital system tumor (epididymis or broad ligament) in 1 member. These families have been previously published: see more information in PMID 29330336 (2 families of 11 people total), and PMID 28388566 (as family #52 (9 members), and #53 (2 members)).

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 was confirmed in family #52 with 9 affected members who were all genetically confirmed with the mutation. A male proband was diagnosed with CNS hemangioblastoma at 28Y, RCC at 28Y, and multiple pancreatic lesions at 28Y. His son and daughter of unknown ages are asymptomatic. His mother was diagnosed with CNS hemangioblastoma at 66Y, RCC at 69Y, and multiple pancreatic lesions at 66Y. His first sister was diagnosed with CNS hemangioblastoma at 32Y, RCC at 36Y, and multiple pancreatic lesions at 36Y. His nephew and niece (son and daughter of first sister) of unknown ages are asymptomatic. His second sister was diagnosed with CNS hemangioblastoma at 39Y, RCC at 39Y, and multiple pancreatic lesions at 39Y. His nephew (son of second sister) of unknown age is asymptomatic. This cohort was also published in a paper by Wang et al., 2018 (PMID: 29330336). It is likely that both papers published the same family.
