A previous study of 26 Japanese, VHL families was extended to 41 additional families. Germline mutations were detected in 55 of 77 Japanese families using SSCP, direct sequencing, and Southern Blot analysis of peripheral blood samples. The S168Tfs*2 (c.503_513del) germline mutation (reported as “c.716del11bp” according to legacy reference sequence) was found in a VHL type 1 family of 3. All three family members had renal cell carcinoma, two had hemangioblastomas of the central nervous system, and one had pancreatic cysts or tumors (unspecified) (family ID 63).
