Serum alanine aspirate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyl transpeptidase (GGT) were higher in NASH patients than non-NASH group (p = 0.223, p = 0.005 and p = 0.006 respectively). This evidence concerns the gene GGTLC1 and metabolic dysfunction-associated steatohepatitis.
