title: Infrequent involvement of p53 mutations and loss of heterozygosity of 17p in the tumorigenesis of renal cell carcinoma.
abstract: Restriction fragment length polymorphism (RFLP) analysis and the polymerase chain reaction of the single-strand conformation polymorphism (PCR-SSCP) method were conducted to assess the loss of heterozygosity of chromosome 17p and mutations of the p53 gene in 30 surgical specimens of human renal cell carcinoma. Six of 29 tumors (20.6%) showed loss of heterozygosity on chromosome 17p in RFLP analysis, and in none of 21 tumors could a mutation be found on exons 5 to 8 of the p53 gene in PCR-SSCP analysis. We conclude that the p53 gene mutation does not play a role in the development of the majority of cases of renal cell carcinoma and that there may be another tumor suppressor gene on 17p.
