Systemic Lupus erythematosus (SLE) is a worldwide autoimmune disease with different presentations. Genetic and environmental factors like infection and ultraviolet light are supposed to be responsible for the development of SLE. Disturbance in cytokines production may be involved in SLE pathogenesis. In this case-control study, we investigate the interleukin-17F (IL-17F) gene polymorphism (7488T/C, rs763780) in Egyptian SLE patients using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). There were no significant changes when both genotypes and alleles for patients and controls were compared with each other. According to the results, no association between the IL-17F gene polymorphism (7488T/C, rs763780) and SLE.
