Moreover, when only cases of HCV-related hepatitis were considered, patients with HCV genotype 1 infection had a statistically lower Bcl-xL mRNA expression (75.38 ± 19.0) than cases with genotype 2 (114.57 ± 34.3, P = 0.010), or genotype 3 (104.85 ± 22.4, P = 0.019). Here, BCL2L1 is linked to hepatitis A virus infection.
