Original Article Relationship between the IL28B gene-related single-nucleotide polymorphism of rs8099917 and susceptibility to hepatitis C infection in Iranian population

Background: The current medical treatment for hepatitis C is a combination of antiviral therapy along with pegylated interferon alpha and ribavirin. Recent studies have demonstrated that single nucleotide polymorphisms near the interleukin 28B gene coding for IFN-λ3 were associated with the antiviral response. Therefore, this study aimed to determine the frequency of G/T polymorphism of rs8099917 among the Iranian population. Materials and Methods: This cross-sectional study was performed on 93 blood samples (71 sensitive and 22 resistant to treatment) collected from individuals suffering from chronic HCV, and 57 healthy controls. DNA was extracted from the samples and the frequency of the polymorphism was analyzed using the PCR-RFLP method. Finally, the products were detected on 3.5 % agarose gel electrophoresis. Results: The frequency of the G/T polymorphism between the healthy individuals an
