Additionally, significant positive correlations were observed between liver enzymes (AST and ALT), markers of liver damage and cholestasis (AST with GGT, ALT with GGT), markers of cellular damage (AST and ALT with LDH), markers of iron deposition (AST and ALT with ferritin), and a cardiac marker (ALT with troponin I), although in this case, the association is negative. The gene discussed is GPT; the disease is cholestasis.
