Germline mutations in 45 unrelated Japanese VHL patients were determined from blood samples using PCR-SSCP or Southern blot analyses. The authors reported a nucleotide deletion (i.e. 476G>C) which coincides with legacy variant nomenclature (AF010238.1) and was mapped to c.263G>C (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 Hb, RCC, and Pheo was available. Case 8 had p.Trp88Ser mutation. All 5 examined family members were affected with renal cell carcinoma. Other demographics of the members were not described.
