Mutations in the ATP8B1 gene cause two autosomal recessive disorders affecting liver: cholestasis, benign recurrent intrahepatic, 1 (BRIC1), cholestasis, progressive familial intrahepatic, 1 (PFIC1) and one autosomal dominant disorder: cholestasis, intrahepatic, of pregnancy, 1 (ICP1). BRIC2 is caused by mutations in the ABCB11 more
