Specific genetic change in tumors associated with von Hippel-Lindau disease.
Previous reports showed that the loss of DNA sequences on the short arm of chromosome 3 (3p) is consistently found in sporadic renal cell carcinomas. To evaluate the significance of this genetic change, we looked for the loss of 3p alleles in hereditary renal cell carcinomas and other tumors from patients with von Hippel-Lindau disease. Specific loss of alleles from chromosome 3p was detected with polymorphic DNA markers in 11 renal cell carcinomas, one pheochromocytoma, two spinal hemangioblastomas and one cerebellar hemangioblastoma from von Hippel-Lindau patients. Multiple renal cell carcinomas in individuals with von Hippel-Lindau disease showed loss of the same chromosome 3p alleles, which demonstrated that the same chromosome was deleted in each tumor. Analysis of haplotypes indicated that the loss of chromosome 3p alleles was from the chromosome bearing the balancing, wild-type allele of the VHL gene. These results are consistent with the concept that the VHL gene is a recessive oncogene. Renal cell carcinoma, pheochromocytoma, and spinal and cerebellar hemangioblastomas develop in predisposed family members when somatic mutational events lead to loss of chromosome 3p sequences bearing the wild-type allele of the VHL gene.
