FRAT2 and metabolic dysfunction-associated steatotic liver disease: Furthermore, we found seven genes in NAFLD&NASH pathogenesis and NAFLD&NASH-associated hepatocarcinogenesis that also played a central role in PBC&PSC pathogenesis and PBC&PSC-associated hepatocarcinogenesis, i.e., two DNA repair-related genes (HIST2H2BE and RFC5), two apoptosis-related genes (ZNF480 and RPL30), and three metabolism-related genes (ALDOB, FRAT2, and TRMT1).
