Inherited forms of Hyperbilirubinemia

Major pathways involved in bilirubin production, conjugation, and excretion. Notes: Both the UB and CB forms are bound by albumin in the plasma and interstitial space and by ligandin in the hepatocyte. The mechanism responsible for transporting unconjugated bilirubin into the hepatocyte has not been identified. 

Gilbert

Crigler-Najjar

 - Decreased/absent UGT1A1

Dubin-Johnson

 - Decreased MRP2
