Abstract
Nonalcoholic fatty liver disease (NAFLD) and alcoholic fatty liver disease (AFLD) are both leading causes of nonviral chronic liver diseases, and the prevalence of these two clinical disorders is constantly growing worldwide.
NAFLD and AFLD share similar natural history, histologic features, and major molecular mechanisms, leading to inflammation and increased fibrogenesis. In this chapter, we revise current knowledge and recent insights regarding the genetic basis of NAFLD and AFLD in an integrative approach to understand the role of the genetic component in the susceptibility of abnormal liver fat accumulation and the progression of liver disease.
