DNA sequencing analysis of p53 gene in tumor samples of clear cell sarcoma of the kidney. DNA sequencing revealed the following: an A → G transition, upstream 9th base from codon 225, in intron (Case 4), a T insertion between codons 162 and 163 (Case 6), and a C → T transversion in codon 289 (Case 7). Cases 4 and 6 showed the sense strand of the p53 gene. Case 7 showed the antisense strand of the p53 gene.
