Finally, all enzymatic liver function parameters (ALT, AST, GGT) presented significant differences between the NAFLD and non NAFLD patients (AST: NAFLD 0.64 ± 0.44 vs. non NAFLD 0.45 ± 0.25, p=0.00, ALT: NAFLD 0.80 ± 0.79 vs. non-NAFLD 0.37 ± 0.20, p=0.00, GGT: NAFLD 0.48 ± 0.42 vs. non NAFLD 0.29 ± 0.11, p=0.00). The gene discussed is GPT; the disease is metabolic dysfunction-associated steatotic liver disease.
