Abstract
This retrospective analysis aimed to investigate the mutation profile of 16 common mutated genes in acute myeloid leukemia (AML) patients. A total of 259 patients who were diagnosed of AML were enrolled in this study. Mutation profiling of 16 candidate genes were performed in bone marrow samples by using Sanger sequencing. We identified at least 1 mutation in 199 of the 259 samples (76.8%), and 2 or more mutations in 31.7% of samples. was the most common mutated gene (16.2%, 42/259), followed by (15.1%, 39/259), (14.7%, 38/259), and (13.5%, 35/259). Concurrence was observed in 97.1% of the mutated cases and in 29.6% of the double mutated cases. Distinct patterns of co-occurrence were observed for different hotspot mutations within the gene: mutations were associated with and/or mutations, whereas mutations co-occurred with mutations only. Concurrence was also observed in 86.6% of epigenetic regulation genes, most of which co-occurred with mutations. The results showed certain rules in the mutation profiling and concurrence of AML patients, which was related to the function classification of genes. Defining the mutation spectrum and mutation pattern of AML will contribute to the comprehensive assessment of patients and identification of new therapeutic targets.
