Hyperbilirubinemia is a clinical condition describing an elevation of blood bilirubin level due to the inability to properly metabolise or excrete bilirubin, a product of erythrocytes breakdown. In severe cases, it is manifested as jaundice, the yellowing of tissues like skin and the sclera when excess bilirubin deposits in them. [1]
Hereditary hyperbilirubinemia refers to a group of conditions where levels of bilirubin, a byproduct of red blood cell metabolism, are elevated in the blood due to a genetic cause. [1] Various mutations of enzymes in the liver cells, which breakdown bilirubin, cause varying elevated levels of bilirubin in the blood. [ 2 ]
Rotor type hyperbilirubinemia is a distinct yet similar disorder to Dubin–Johnson syndrome [1] – both diseases cause an increase in conjugated bilirubin, but Rotor syndrome differs in that it is a result of impaired hepatocellular storage of conjugated bilirubin that leaks into plasma causing hyperbilirubinemia.
Gilbert syndrome (GS) is a syndrome in which the liver of affected individuals processes bilirubin more slowly than the majority. [1] Many people never have symptoms. [1] Occasionally jaundice (a slight yellowish color of the skin or whites of the eyes) may occur. [1]
The most commonly associated symptoms of jaundice are itchiness, [2] pale feces, and dark urine. [4] Normal levels of bilirubin in blood are below 1.0 mg/dl (17 μmol/L), while levels over 2–3 mg/dl (34–51 μmol/L) typically result in jaundice. [4] [9] High blood bilirubin is divided into two types: unconjugated and conjugated bilirubin. [10]
Around 80 to 99% of people with Dubin–Johnson syndrome have jaundice, [3] [4] abnormal urinary color, biliary tract abnormality, and conjugated bilirubinemia. [4] Around 30 to 79% of people with the disorder have abnormality of the gastric mucosa. [4] Other rare symptoms include fever and fatigue. [3]

Pathological jaundice in newborns should be suspected when the serum bilirubin level rises by more than 5 mg/dL per day, serum bilirubin more than the physiological range, clinical jaundice more than 2 weeks, and conjugated bilirubin (dark urine staining clothes). Haemolytic jaundice is the commonest cause of pathological jaundice.
