MTTP and chronic hepatitis C virus infection: Our results provide evidence that in patients with chronic hepatitis C the interaction between HCV genotype 3 and the GT/TT genotype (as opposed to the GG genotype) of the MTTP -493G/T SNP increases the risk of steatosis by 25.22-fold, which may indicate that this SNP has a significant influence on the accumulation of triglycerides in hepatocytes.
