Canalicular bile acide transporte ABCB11, BSEP

Anomalies

- BSEP/ABCB11 germline mutations in

  • progressive familial intrahepatic cholestasis type 2 (PFIC2) (MIM.601847)
  • benign recurrent intrahepatic cholestasis type 2 (BRIC2) (MIM.605479)
    • Benign recurrent intrahepatic cholestasis (BRIC) is characterized by intermittent episodes of cholestasis without progression to liver failure.
    • The cholestatic attacks vary in severity and duration and patients are asymptomatic between episodes, both clinically and biochemically

IHC

- BSEP and MDR3 are useful Immunohistochemical Markers to Discriminate Hepatocellular Carcinomas From Intrahepatic Cholangiocarcinomas and Hepatoid Carcinomas. (26735860)
