Genetics of Nonalcoholic Fatty Liver Disease: From Pathogenesis to Therapeutics

Semin Liver Dis DOI: 10.1055/s-0039-1679920Here, the authors review the remarkable genetic discoveries that have illuminated the biology of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). The authors integrate genes associated with NAFLD and NASH into regulatory pathways to elucidate the disease pathogenesis. They review the evidence for molecular mediators of chronic liver damage, which suggests that convergent pathophenotypes, including inflammation and fibrosis, share common genetic modifiers. They further demonstrate that genes involved in the genetic susceptibility of NAFLD and NASH participate in cross-phenotype associations with diseases of the metabolic syndrome, including type 2 diabetes, obesity, and cardiovascular disease. However, immune-related loci associated with NAFLD and NASH exhibit some level of pleiotropy influencing disparate phenotypes, such as premature birth or sepsis. They finally focus on the translation of current genetic knowledge of NAFLD and NASH toward precision medicine. They provide evidence of genetic findings that can be leveraged to identify therapeutic targets.
