To examine the pathogenic role of MDR3 (ABCB4) transporter defects in adult and neonatal cholestatic syndromes.
Narrative synthesis of clinical genetics and pathophysiology involving ATP-binding cassette transporter defects in human cholestasis.
Evaluation of findings from human hereditary liver diseases alongside mechanistic data from rodent Mdr2-knockout cholangitis models.
MDR3 mutations impair biliary excretion of phosphatidylcholine, driving a spectrum of pathologies including progressive familial intrahepatic cholestasis, adult biliary cirrhosis, intrahepatic cholestasis of pregnancy, and drug-induced liver injury.
Rodent Mdr2-knockout models and clinical observations indicate that MDR3 sequence variants likely serve as disease-modifying factors in primary biliary cirrhosis and primary sclerosing cholangitis.
Pharmacological agents that modulate MDR3 expression and transporter function represent viable therapeutic targets for adult cholestatic liver disorders.
