Crigler-Najjar syndrome (CNS) is a genetic disorder. It has a mostly autosomal recessive pattern of inheritance. Unconjugated to conjugated bilirubin conversion in the liver requires the enzyme Uridine 5’-diphosphate-glucuronosyltransferase (UDP-glucuronosyltransferase), which is absent or exhibits low activity in CNS. It is a significant contributor to congenital nonhemolytic jaundice. Following an aberrant gene mutation causes an increase in the bilirubin burden in the blood and is inherited within families. We present a case of a 22-year-old man who has had type I CNS since birth. There is minimal neurological damage, but there is a considerable increase in unconjugated bilirubin. Phenobarbital therapy had no impact on the reduction of bilirubin load. The primary goal is to reduce unconjugated bilirubin, although liver transplantation is the only curative treatment option for type I CNS.
