Familial forms of cryptogenic cirrhosis have been described. We have cared for families in which several members were afflicted with cryptogenic cirrhosis as well as the more recently recognized entity of nonalcoholic steatohepatitis. To examine the familial patterns of these disorders, we reviewed patients with nonalcoholic steatohepatitis, with and without cirrhosis, or cryptogenic cirrhosis to assess how frequently their relatives were afflicted with these disorders. ⋯ The coexistence of nonalcoholic steatohepatitis with and without cirrhosis and cryptogenic cirrhosis within these kindreds suggests a common pathogenesis and possible genetic risk. These disorders were frequently but not invariably associated with female sex, obesity, and type 2 diabetes.
