Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Phenotypes
PFIC1; progressive familial intrahepatic cholestasis type 1; benign recurrent intrahepatic cholestasis; intrahepatic cholestasis of pregnancy; modifier in other genetic causes of cholestasis
Majority of pathogenic variants are missense; but there are also nonsense and splicing variants
