Detection of TP53 Mutation in Acute Myeloid Leukemia by RT-PCR-Based Sanger Sequencing.

The TP53 gene is known to be one of the most frequently mutated genes in various human cancers. In de novo acute myeloid leukemia (AML), TP53 has been found to be mutated in ~10% of patients. Although the frequency of TP53 mutations in AML is substantially lower compared to other human cancers, TP53 mutations in AML are associated with poor response to chemotherapy and poor outcomes. Therefore, assessment of TP53 status is critical in clinical routines and research studies. In this chapter, we described the use of conventional RT-PCR for rapid detection of TP53 mutations by Sanger sequencing. We use AML cells as an example but provide sufficient details for usage in other cell types.
