About this section


Fully expand this MalaCard
NIH Rare Diseases:42 Crigler najjar syndrome, type 2 is caused by mutations in the ugt1a1 gene. the gene mutation causes the body to be unable to make adequate enzyme to convert bilirubin into a form that can easily be removed from the body. without this enzyme, bilirubin can build up in the body and lead to extraordinarily yellow skin and eyes (jaundice). this condition is less severe than the type 1 form, however the severity of type ii can vary greatly. almost all patients with crigler najjar syndrome, type 2 develop normally, but there is a risk for some neurologic damage from kernicterus (bilirubin accumulation in the brain). in general people with type 2 crigler najjar syndrome have serum bilirubin levels ranging from 20 to 45 mg/dl. phenobarbital treatment is the standard therapy for this condition and can often help to drastically reduce the bilirubin levels. last updated: 1/19/2011

MalaCards based summary: Crigler Najjar Syndrome, Type 2, also known as crigler-najjar syndrome, type ii, is related to crigler-najjar syndrome and gilbert syndrome, and has symptoms including hepatitis/icterus/cholestasisand autosomal recessive inheritance. An important gene associated with Crigler Najjar Syndrome, Type 2 is UGT1A1 (UDP glucuronosyltransferase 1 family, polypeptide A1), and among its related pathways are Steroid hormone biosynthesis and Chemical carcinogenesis. The compounds n-acetylbenzidine and n-hydroxy phip have been mentioned in the context of this disorder. Affiliated tissues include eye, brain and skin.
