Atp8b1 and Abcb11 Analysis in 62 Children With Normal Gamma-Glutamyl Transferase Progressive Familial Intrahepatic Cholestasis (Pfic): Phenotypic Differences Between Pfic1 and Pfic2 and Natural History

Abstract

PFIC1 and PFIC2 differ clinically, biochemically, and histologically at presentation and/or during the disease course. A small proportion of normal-GGT PFIC is likely not due to ATP8B1 or ABCB11 mutations.
