MT-TP and hepatitis C virus infection: Specifically, Rosa Zampino et al. [16] found no significant correlation between MTTP gene polymorphisms and hepatic steatosis patients presenting with hepatitis C. In contrast, Mirandola et al. [17] reported the MTTP genotype (-493G/T) T allele significantly increases the probability of liver steatosis in a population not carrying the HCV genotype 3.
