Cholestatic liver diseases related to ABCB4 variants include progressive familial intrahepatic cholestasis type 3 (PFIC3), benign recurrent intrahepatic cholestasis, intrahepatic cholestasis of pregnancy (ICP), drug-induced liver injury (DILI), and low phospholipid associated cholelithiasis (LPAC) [1, 6]. This evidence concerns the gene ABCB4 and progressive familial intrahepatic cholestasis type 3.
