چکیده
Objectives The study aims to understand geneome diversi?cation and complexity that developed in Acute myeloid leukemia (AML).Methods Next-generation sequencing (NGS) was used identify the genetic pro?les of 22 genes relevant hematological malignancy 204 patients with de novo non-M3 AML.Results At time initial diagnosis, at least one mutation identified 80.9% (165/204). most commonly mutated gene NPM1 (22.1%), followed by ASXL1 (18.1%), TET2 IDH2 (15.7%), CEBPA (14.7%), FLT3-ITD (13.2%) DNMT3A (11.8%). Mutations landscape analysis indicated several patterns co-occurring mutual exclusive mutations. Some correlation observed between mutations clinicohematological features. Multivariate showed age >60 years, karyotypes, KIT were independent unfavorable prognostic factors for OS; NPM1-mut/ FLT3-ITD-wt independently correlated prolonged whereas poor risk RFS high WBC RUNX1 mutation. According different genotype demonstrated multivariate analysis, 163 intermediate-risk cytogenetics classified into three subgroups: or biallelic as favorable risk, KIT, IDH2, TP53 NRAS remaining intermediate risk. We also obtain information clonal evolution during progression observing five who underwent repeat NGS relapse our cohort.Conclusion techniques is a useful tool discovering related AML genomes, leading novel targeted therapeutic approaches could improve outcomes.

Evaluation of the CD123 Expression and FLT3 Gene Mutations in Patients with Acute Myeloid Leukemia
Background and Objective: Identification of cytogenetic and molecular changes plays an important role in acute myeloid leukemia (AML) patients. Thus, they are used in classification, prognosis and treatment of the disease. The CD123 expression and FLT3 gene mutations are also the variations that may assist in prognosis and treatment of patients with AML.Methods:</...

Background: Osteogenesis imperfecta (OI) is a clinically and genetically heterogeneous disorder characterized by bone loss and bone fragility. The aim of this study was to investigate the variants of three genes involved in the pathogenesis of OI. Methods: Molecular genetic analyses were performed for COL1A1, COL1A2, and CRTAP genes in an Iranian family with OI. The DNA samples were analyzed by...
متن کاملDetection of R882 Mutations in DNMT3A Gene in Acute Myeloid Leukemia: A Method Comparison Study
Background: Somatic mutations in the hotspot region of the DNA-methyltransferase 3A (DNMT3A) gene were recurrently identified in acute myeloid leukemia (AML). It is believed that DNMT3A mutations confer an adverse prognosis for AML patients. These lines of evidence support the need for a rapid and cost-efficient method for the detection of these mutations. The present study aimed to establish h...
متن کاملGeographic Heterogeneity of the AML1-ETO Fusion Gene in Iranian Patients with Acute Myeloid Leukemia
Background: The human AML1 gene, located on chromosome 21, can be fused to the AML1- eight-twenty-one (ETO) oncoprotein on chromosome eight, resulting in a t(8;21)(q22;q22) translocation. Acute myeloid leukemia (AML) associated with this translocation is considered a distinct AML with a favorable prognosis. Due to the various incidences of the translocation, which is associated with geographic ...
