IRF-1 acts as a tumor suppressor gene, and is inactivated in chronic (CML) and non-chronic myelogenous leukemia (non-CML). In the light of numerous reports on genetic changes in the noncoding region of the IRF-1 gene, this study aimed to explore possible genomic changes in coding and non-coding regions of IRF-1 in a random sample of leukemic Saudi patients, in order to obtain insights into potential impact of genetic changes on clinicopathological characteristics. Patients were classified into two major leukemia subtypes: CML (8 cases; 36.4%) and non-CML (14 cases; 63.6%). Sequencing results revealed two novel mutations in the coding area of the IRF-1 gene likely to influence the IRF-1/DNA binding affinity. In addition, three mutational sites in the non-coding region between exon 5&6 (8985(T>G), 8,990(T>G) and 8995(A>G) were identified. In conclusion, a larger representative study might help provide better understanding of the possible contribution of the identified genetic changes in IRF-1 to disease prognosis and outcomes in leukemic patients.
