ABSTRACT
OBJECTIVE@#To investigate the incidence of Runt-related transcription factor 1 (RUNX1) gene and its associated gene mutations in patients with acute myeloid leukemia (AML), and analyze its clinical characteristics and prognosis.@*METHODS@#The genomic DNA-PCR method was used to detect the exon of RUNX1 gene, and the gene mutations were analyzed by genetic sequencing. NPM1, DNMT3A, FLT3-ITD, IDH1/2, K/N-RAS, CEPBA, TET2, and WT1 co-mutations were also detected. Patients were followed up to determine efficacy and prognosis.@*RESULTS@#Among 171 patients, the RUNX1 gene mutation was detected in 17 cases, and the mutation rate was 9.9%. The type of RUNX1 gene mutation was 9 missense mutations, 4 frameshift mutations, and 4 nonsense mutations. The peripheral blood leukocyte count of the patients in mutation group was 3 (1-101) ×10@*CONCLUSION@#AML patients with RUNX1 gene mutation shows unique clinical and biological characteristics, RUNX1 mutation can be regarded as a molecular marker of poor prognosis in AML patients.
