    Abstract

    Background: Systemic lupus erythematosus (SLE) is a chronic disease of autoimmune nature. Genetic pre-disposition has been known to play a role. With a number of genes already named, the IL-RA is no exception. Polymorphism in the human cytokine gene, an uncommon allele of a variable repeat polymorphism in intron 2 of the IL1-RA gene has been found to be associated with SLE. Objective: The aim of this present study was to study the polymorphism of the IL-1RA gene in Malay and Chinese SLE patients and to investigate the possible contribution of the IL-RA gene polymorphism in disease susceptibility. Materials and Methods: We thus investigated the allele frequencies of the IL-RA gene polymorphism in 87 Malay and 100 Chinese SLE population at the Hospital of National University of Malaysia, Kuala Lumpur by PCR and direct analysis by electrophoresis on agarose gel. Unrelated healthy ethnically-matched individuals were taken as controls. Results: Allelic frequencies of the IL1-RN*4 were most dominant in all groups (patients and controls) but there was no significant differences among them. We found an increased allelic frequency and carriage rate of the IL1-RN*2 repeat in both the Malay and Chinese SLE cases compared to controls. However they were not statistically significant. Conclusion: Thus from this finding we postulate that the polymorphism of the IL-1RA gene (both alleles 2 and 4) does not influence susceptibility to SLE.
