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]

Gilbert syndrome is due to a genetic variant in the UGT1A1 gene which results in decreased activity of the bilirubin uridine diphosphate glucuronosyltransferase enzyme.[1][3] It is typically inherited in an autosomal recessive pattern and occasionally in an autosomal dominant pattern depending on the type of variant.[3] Episodes of jaundice may be triggered by stress such as exercise, menstruation, or not eating.[3] Diagnosis is based on higher levels of unconjugated bilirubin in the blood without either signs of other liver problems or red blood cell breakdown.[2][3]

Typically no treatment is needed.[1] Gilbert syndrome is associated with decreased cardiovascular health risks.[4] If jaundice is significant phenobarbital may be used, which aids in the conjugation of bilirubin.[1] Gilbert syndrome affects about 5% of people in the United States.[3] Males are more often diagnosed than females.[1] It is often not noticed until late childhood to early adulthood.[2] The condition was first described in 1901 by Augustin Nicolas Gilbert.[5][2][6]
