Abstract

Aim: The aim of this case-control study was to investigate association of G/T IL-21 (rs2055979) and C/T IL-21R (rs3093390) gene Polymorphisms with chronic Hepatitis C virus in Iranian Patients. Background: Interleukin 21 (IL-21) has a significant function in the regulation of cellular immune responses. Its exclusive receptor, IL-21R, expressed on the surface of T, B and NK cells and is important for the proliferation and differentiation of these immune cells. Hence, it was suggested to be involved in response to viral infections. Methods: This study follows a case-control study design and blood samples were collected from 290 patients with chronic HCV and 290 controls for both genes. Genomic DNA was extracted and then for each position, SNP was genotyped by the dedicated PCR and restriction fragment length Polymorphism (RFLP) method. The results were analyzed by SPSS software using logistic regression and Chi-square tests. Results: Genotype frequencies of GG, GT and TT in IL21 gene (rs3093390) were found to be 27. 6%, 48. 3%, 24. 1% and 25. 2%, 55, 5%, 19, 3% respectively in HCV infected patients and control group. For IL21R gene (rs2055979) genotype frequencies of CC, CT and TT were 63. 8%, 31. 4%, 4. 8% and 61. 4%, 29. 7%, 9. 0% respectively in HCV infected patients and control group. P values for genotype and allele frequencies were p=0. 188, p=0. 769 for IL21 gene, and p=0. 144, p=0. 179 for IL21R gene respectively. Conclusion: As a result, there is no evidence for an association between IL-21 (rs2055979) and IL-21R (rs3093390) gene Polymorphisms with chronic Hepatitis C virus in Iranian Patients.
