      GroupInfo: This germline familial VHL mutation was taken from the National Cancer Institute database, with an unknown number of members belonging to two family IDs: Family 4414NCI and 4577NCI. Table 4 lists all ID and mutations associated with individuals with pheochromocytoma.

    1. In a study of 114 unrelated VHL families, 85 germline mutations were found. VHL mutations were detected in affected family members, but not in unaffected family members or 96 normal individuals. This missense mutation was found in a VHL type 2B family of 7 individuals (Family ID 4414), using PCR and SSCP sequencing. The mutation of c.357C>G was referred to in the paper by c.570C>G due to a difference in transcript sequence. Two of seven individuals were identified with retinal hemangioblastomas, 3 with CNS hemangioblastomas, one with renal cell carcinoma, and one with pheochromocytomas. Supporting evidence of pathogenicity because cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease (ACMG code: PP1).
