“…Thomas et al [6] genotyped the rs12979860 SNP in HCV patients, from six cohorts, with well-characterized spontaneous clearance of HCV or viral perseverance and demonstrated that the genotype was strongly related to the clearance HCV. The level of IL-28B is a type of T-helper interleukins, a class II cytokine receptor ligand, a 200 amino acid long protein, a member of type III IFN-s, that indistinctly structurally relates to the members of IL-10 superfamily of cytokines, but parts also partial sequence similarity and efficient features with the type I IFN-s (α, β) [5]. Qahtani et al [7] found that there is a association between serum IL28B levels and the different SNP genotypes, a box-plot investigation was achieved for the diverse SNPs against average logarithmic values of IL28B levels.…”
