Finally, we also analyzed the relationship between MTTP genotypes and susceptibility to hepatic steatosis in different HCV genotypes, but found no increased risk in patients infected by the HCV genotype 1 and harboring MTTP recessive model mutations (OR = 0.862, 95% CIs: 0.443–1.676, P = 0.661, Fig. 7). The gene discussed is MTTP; the disease is Hepatic steatosis.
