Germline mutations in 45 unrelated Japanese VHL patients were determined from blood samples using PCR-SSCP or Southern blot analyses. The authors reported variants in legacy variant nomenclature (AF010238.1) so this variant was mapped to c.429_439del (NM_000551.3). PCR-SSCP or Southern blot analyses of the DNA from family members showed that mutations were segregated with disease phenotype in VHL families, although this data was not shown. Data on the presence of retinal angioma, CNS hemangioblastoma (Hb) renal cell carcinoma (RCC), and pheochromocytoma was available. Case 26 had a G144fs (c.429_439del) frameshift mutation. 1 member was affected with retinal angioma, CNS hemangioblastoma, and renal cell carcinoma. Other demographics of the members were not described.
