In the final multiple logistic regression model used to determine which characteristics combined with each SNP to influence the presence of hepatic steatosis in patients with chronic hepatitis C, it was observed that in the dominant genetic model (GG × GT/TT), the GT/TT genotype of the -493G/T SNP in the MTTP gene combined with HCV genotype 3 infection presented an 11.51-fold higher risk of hepatic steatosis than that observed in carriers of the GG genotype without HCV genotype 3 infections (95% CI 2.08‒63.59, p = 0.005). The gene discussed is MTTP; the disease is fatty liver disease.
