Thirteen new p53 gene mutants identified among 41 human breast cancer cell lines.

Abstract excerpt

The p53 tumor suppressor gene is frequently mutated in breast cancer. Here, we used direct sequencing to screen the complete coding sequence of the p53 gene from 41 human breast cancer cell lines. We identified 32 cell lines (78%) with a p53 gene alteration that predicted a change in the encoded protein. Thirty-one of these mutations were accompanied by loss of the other p53 allele. All mutations but one were...
