Zampino et al. [8] found an association between the T allele of the polymorphism and high degrees of fatty liver accumulation in patients infected with HCV genotype 3; conversely, Mirandola et al. [30] found that the GT/TT MTTP genotype was the main risk factor associated with a higher degree of steatosis in HCV genotype non-3. The gene discussed is MT-TP; the disease is Hepatic steatosis.
