Jaundice occurs when this pathway is disrupted. The specific cause of the problem cannot be identified. In pre-hepatic jaundice, there is excessive red cell breakdown which overwhelms the liver's ability to conjugate bilirubin. Pathologic elevation of conjugated or direct bilirubin (concentration higher than 2 mg/dL or more than 20% of total bilirubin) is termed conjugated hyperbilirubinemia.

Neonatal cholestasis (poor bile flow in a young baby) can be caused by several things. Neonatal hepatitis refers to many forms of liver dysfunction that affects fetuses and neonates. In the context of medical liver disease: Grade = inflammation/activity. The liver is commonly affected, and in severe cases, these disorders can lead to cirrhosis . Infants with this condition are usually jaundiced.
