Summaries for Crigler-Najjar Syndrome, Type Ii

About this section
NIH Rare Diseases:45 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 Ii, also known as crigler najjar syndrome, type 2, is related to gilbert syndrome and kernicterus, and has symptoms including abnormality of the liver, autosomal recessive inheritance and jaundice. An important gene associated with Crigler-Najjar Syndrome, Type Ii is UGT1A1 (UDP Glucuronosyltransferase 1 Family, Polypeptide A1), and among its related pathways are Statin Pathway - Generalized, Pharmacokinetics and Nicotine Pathway, Pharmacokinetics. Affiliated tissues include skin, brain and eye.

UniProtKB/Swiss-Prot:67 Crigler-Najjar syndrome 2: Patients have less severe hyperbilirubinemia and usually survive into adulthood without neurologic damage. Phenobarbital, which induces the partially deficient glucuronyl transferase, can diminish the jaundice. CN2 inheritance is autosomal dominant.
