As a result, it seems that in the acute phase of HCV infection with viral genotypes 1 or 4, those who have IL28B rs12979860 CC genotype clear the virus better than rs12979860 T allele carriers, so in the chronic hepatitis C with HCV genotype 1, rs12979860 CC genotype is seen in lower frequency than the healthy group. Here, IFNL3 is linked to chronic hepatitis C virus infection.
