Environmental and different genetic factors affect disease process, prognosis and treatment. Among different genetic factors NPM1, FLT3, MLL and BAALC genes are the most effective on patient&#39;s survival rate. The aim of this study was to assess amount of BAALC gene expression in AML patients, and its relation to survival rate.</p> <p style="text-align: justify"><strong>&nbsp; Methods:</strong> In this case-control study, from all 94 individuals referred to Ghaem Medical Center during 2012-2015, 47 cases were normal cytogenetic AML and others were healthy individuals that were studied as control group. Real-time PCR method was applied for gene expression evaluation. Other information of patients was extracted from medical documents. SPSS v.21 was used for data processing.</p> <p style="text-align: justify"><strong>&nbsp; Results:</strong> Mean age of studied cases was 31.50 years. The most of BAALC gene expression was seen in M1 and M2 subtypes, and the less was in M5. A significant relation was found between amount of gene expression and patient&#39;s survival rate.</p> <p style="text-align: justify"><strong>&nbsp; Conclusion:</strong> BAALC gene expression was increased significantly in AML cases. BAALC expression had reverse relation with patients&#39; survival rate in North-East of Iran.</p> Acute myeloid leukemia, Survival rate, Prognosisampus. 852 856 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1-1051&slc_lang=en&sid=1 Mojgan Amirpour amirpourm1@mums.ac.ir 200319475328460024535 200319475328460024535 No Mashhad University of Medical Sciences, Mashhad, Iran.
