High-throughput sequencing methods reveal characteristic mutation spectra in leukemia associated with different chromosomal disorders. However, the role of mutation events in malignant cell transformation processes remains obscure. We searched for driver mutation events in leukemic cells containing the chimeric CBFB-MYH11 gene, which results from inversion of chromosome 16. Using target enrichment, the coding regions of 84 genes in genomes of 12 children with acute myeloid leukemia with inv(16) were investigated. Somatic mutations have been found in the genes of the proteins of intracellular signaling cascades mediated by receptor tyrosine kinases, such as KIT (41%), NRAS (25%), KRAS (17%), and FLT3 (8.3%). Comparative analysis of samples at the time of diagnosis and during remission was used to assess the role of mutations in the pathogenesis of the disease. Previously undescribed mutations in the KDM6A, NOTCH1, and IDH1 genes, which may be involved in leukemogenesis processes have been identified. massive parallel sequencing, acute myeloid leukemia, somatic mutations, inversion 16 |
