    ### Instruction:
    What are the genetic changes related to cryptogenic cirrhosis ?
    ### Response:
    Unlike most cases of cirrhosis, cryptogenic cirrhosis is not caused by the hepatitis C or B virus or chronic alcohol use. A diagnosis of cryptogenic cirrhosis is typically given when all other causes of cirrhosis have been ruled out. When a disorder occurs without an apparent underlying reason, it is described as cryptogenic.
