Besides this, four more common genes have been identified: leptin (LEP), adiponectin (ADIPOQ), aryl hydrocarbon receptor (AHR), and transforming growth factor beta-1 (TGFB1) genes, the expression of which is typical for patients with AH, NAFLD, liver fibrosis, and the presence of systemic inflammation [141]. This evidence concerns the gene AHR and metabolic dysfunction-associated steatotic liver disease.
