Abstract excerpt
A total of 76 primary breast cancers were screened for p53 mutations using the yeast p53 functional assay, and the mutations were determined by DNA sequencing. Clonal mutations of p53 were detected in 30 tumors (39%). Immunohistochemical staining for nuclear p53 accumulation performed on the yeast assay-positive cases clearly differentiated missense mutations in the DNA binding domain (contact mutant; 17 cases)...
