A cohort of 141 patients with hemangioblastomas of the central nervous system was analyzed. 81 patients had germline mutations in the VHL gene, analyzed through peripheral blood by Southern blotting and SSCP analysis. This splice site mutation (c.464-2A>G) was recorded in the paper as c.677-2A>G due to a difference in transcript sequence. It was found in one patient with a hemangioblastoma of the central nervous system. Any family information is unknown. No other phenotypes described.

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.

Of 65 VHL families from central Europe, 53 were identified with germline mutations using SSCP analysis of PCR products by peripheral blood. This splice mutation was found in a Italian, VHL type 1 family. Only one affected patient was identified with retinal angiomas, hemangioblastomas of the central nervous system, renal cell carcinoma, pancreatic cysts and cystadenomas of the epididymis. (family VHL 31). The c.464-2A>G mutation was detected in the patient, referred to in the paper by c.677-2A>G due to a difference in transcript sequence.

GroupID/ KindredID: VHL 31

Case: Sex unknown, Age unknown, Italian

DiseaseAssertion: assumed VHL

FamilyInfo: One patient with the given mutation is stated to belong to VHL family 31 - this was said to be not inherited from either parent, indicating a de novo germline mutation.

Germline mutational data on VHL was gathered from various countries to assess variation in germline mutations that produce disease within different populations. Families were grouped according to three possible outcomes of disease: renal cell carcinoma without pheochromocytoma, renal cell carcinoma with pheochromocytoma, or pheochromocytoma alone. SSCP and denaturing gradient gel electrophoresis identified mutations in 300/469 (63%) of families affected with VHL. This germline familial VHL mutation (c.464-2A>G) was taken from the Bristol Myers Squibb database, and the Munich, university of Freiburg and Institute of Pathology database. It had an unknown number of members belonging to Family ID 31CE, reported in Table 3, as being found in VHL families without pheochromocytoma, and with renal cell carcinoma. Additionally, it was reported in table 5, specified as families without detailed clinical information, under family ID 28BMS. It was reported in the paper as c.677-2A>G due to a difference in transcript reference.
