Popis: Background AML is a complex and heterogeneous disease. The KRAS gene is one of the important genes in the pathogenesis of acute myeloid leukemia (AML). Mutant RAS can promote oncogenesis via different mechanisms including oncogenic transcription, cell cycle progression, cellular survival, growth, metabolism, and cell migration. Therefore, it is important to identify the genomic landscape of AML. The aim of the study is to identify KRAS variants in AML and their association with clinic pathological criteria and possible effects on prognosis using NGS.Method Hotspot mutations in the KRAS gene were studied using Ion S5 next-generation sequencing system. Bone marrow samples of newly diagnosed AML patients were collected to identify hotspot mutations in the KRAS gene. DNA amplicons were subjected to sequencing and were analyzed using ion torrent software. Patients were classified according to the FAB classification system. Patients are also classified according to the cytogenetic groups and the ELN risk stratification system.Results KRAS mutations were detected in exon 2, 3, whereas no mutations in KRAS exon 1. Interestingly, Novel mutations were detected in KRAS in AML Egyptian patients. Also, there was no statistically significant association of RAS mutations with different clinical and prognostic parameters. However, KRAS mutant patients tended to have increased PB WBC counts, percentage of PB, and bone marrow blasts.Conclusion NGS is considered a useful tool to identify KRAS variants that could be useful for risk stratification and tailored therapy in AML patients
