Polymorphisms in the IL-2 gene are associated with various diseases and cancers including non-Hodgkin lymphoma (NHL). The aim of the study is to assess the impact of IL-2 genetic polymorphisms [- 330 T/G (rs2069762) and + 114 T/G (rs2069763)] on the susceptibility and prognosis of NHL. Sixty patients with NHL as well as 60 age and sex matched healthy control subjects are included in this study. IL-2 genotypes were determined by Polymerase Chain Reaction-Restriction Fragment length Polymorphism assay (PCR-RFLP). Our study revealed that both IL-2 rs2069762 and rs2069763 gene polymorphisms are associated with increased risk of developing NHL; OR = 3.609 (95% CI = 1.527-8.417) and 4.142 (95% CI = 1.637-10.538) respectively. Moreover, the simultaneous presence of both polymorphisms is associated with about 6 fold increased risk of developing NHL. Also, IL-2 rs2069762 and rs2069763 gene polymorphisms increase the risk of unfavorable prognosis with OR = 17.300 (95% CI = 3.392-87.725) and 10.424(95% CI = 1.870-58.413) respectively. These findings suggest that IL-2 (rs2069762) and (rs2069763) gene polymorphisms could be involved in the development of NHL.
