Current clinical selection criteria for donor livers include liver function tests to evaluate the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) [12, 13], total bilirubin, blood type compatibility between the donor and recipient [14, 15], absence of viral infections such as Hepatitis and HIV [16, 17], assessment of alcohol and drug-induced liver damage and histopathological evaluation of liver biopsy for steatosis, fibrosis, and necrosis [18, 19]. The gene discussed is GPT; the disease is viral infectious disease.
