Liver function test results showing elevated AST, ALT, and GGT levels, indicating hepatocellular injury. Hyperbilirubinemia (both direct and indirect) reflects cholestatic and hepatocellular dysfunction. A prolonged PT and elevated INR suggest impaired hepatic synthetic function. Hypoalbuminemia further supports the diagnosis of decompensated cirrhosis. The gene discussed is GPT; the disease is Hyperbilirubinemia.
