Ency. home Disease C Crigler-Najjar syndrome Overview Symptoms Treatment Prevention Alternative names: Glucuronyl transferase deficiency (type I); Arias syndrome (type II Crigler-Najjar) Definition: Crigler-Najjar syndrome is an inherited disorder of bilirubin metabolism in which bilirubin cannot be changed into its water-soluble form, bilirubin glucuronide. This is caused by abnormal genes which fail to produce a functional enzyme (bilirubin glucuronyltransferase) capable of converting bilirubin into a water-soluble and therefore, easily excreted form. As a result of the defect, bilirubin can build up in the body causing organs to not work properly and jaundice (a yellow discoloration of the skin and eyes because bilirubin is yellow colored). Causes and Risks Crigler-Najjar syndrome is inherited as an autosomal recessive trait. Parents who are carriers of this condition have about half the normal enzyme activity of a normal adult. Infants who inherit the trait from both parents (this is called homozygous for the abnormal gene) develop severe jaundice (hyperbilirubinemia) beginning a few days after birth. If these infants are not treated, they may develop

What: Treatment of Crigler-Najjar Syndrome: First international conference on rare, fatal liver disease that affects Amish, Mennonites and others. Who: Experts from around the world When: Monday, May 27, 8 a.m. to 5:45 p.m., and Tuesday, May 28, 8 a.m. to noon Where: Weiss Building, Room 305, at The Rockefeller University 1230 York Ave., New York City Crigler-Najjar Syndrome is a nearly always fatal genetic disorder that afflicts newborns. The disease is a deficiency in an enzyme that people need to control the production of bilirubin. When too much bilirubin accumulates, jaundice and severe brain damage occurs. Bilirubin is produced during the breakdown of hemoglobin, the blood's oxygen-carrying red pigment. Currently the disease is treated with phototherapy, to breakdown the bilirubin, followed by liver transplantation. However, liver transplantations may take place after permanent brain damage occurs. Investigators at The Rockefeller University have developed tin-mesoporphyrin, a drug that inhibits hemoglobin from breaking down. Currently, scientists are testing the drug in clinical trials. While the disease occurs worldwide, populations such as the Amish and Mennonites in which family and genetic histories can be established, afford an excellent opportunity for scientists and health care professionals to learn more about Crigler-Najjar Syndrome. Expected as attendees are a 31-year-old woman who is the oldest known living patient with Crigler-Najjar Syndrome, five Mennonite children with the disorder and their families as well as parents of patients from the United States, Canada, England, Germany and India.

    CRIGLER-NAJJAR SYNDROME - I
    DEFINITION:
    An inherited disorder of bilirubin metabolism resulting in chronic, severe unconjugated hyperbilirubinemia and jaundice.
    EPIDEMIOLOGY:
    • incidence: rare (about 70 cases reported)
    • age of onset:
      • newborn (2nd to 3rd week of life)
    • risk factors:
      • familial - autosomal recessive
        • chrom.#: 1q21-q23
        • gene: UDP-glucuronosyltransferase
      • M = F
      PATHOGENESIS:
      1. Background
      • UDP-glucuronosyltransferase is an enzyme which conjugates bili-rubin in the liver
      • there are two forms of Crigler-Najjar Syndrome based upon the degree of UDP-glucuronosyltrasferase deficiency:
      • Type I: severe form
      • Type II: mild-moderate form (also called Gilbert Syndrome)
      2. Genetic Defect
    • CLINICAL FEATURES:
      1. Gastrointestinal Manifestations
      • persistent icterus and jaundice
      • pale yellow stools
      2. Neurological Manifestations
    • 1. Kernicterus
      • presents in the newborn period in 75% of cases
      • eventually develops in all patients despite therapy

    Background: Crigler-Najjar syndrome (CNS) is a rare disorder of bilirubin metabolism and has 2 distinct forms: type 1 and type 2. Type 1 CNS is associated with neonatal jaundice and neurologic manifestations, whereas type 2 CNS (also called Arias syndrome) manifests as a lower serum bilirubin level. Affected individuals may survive to adulthood without any neurological impairment. The differential diagnosis of hyperbilirubinemia can be divided into 3 broad groups: (1) disorders of excessive bilirubin production (eg, hemolysis, ineffective erythropoiesis), (2) impaired hepatic handling of bilirubin (eg, hepatitis, cirrhosis, inherited syndromes), and (3) defective bile outflow (eg, intrahepatic or extrahepatic biliary obstruction). A markedly elevated unconjugated (indirect) hyperbilirubinemia is observed in inherited disorders such as Gilbert syndrome and CNS. Among the inherited unconjugated hyperbilirubinemias, Gilbert syndrome is believed to affect approximately 3-7% of the adult population. CNS is a much rarer disorder, with only a few hundred cases described in the literature.

    Arias’ syndrome
    Synonyms:
    Congenital familial non-haeomolytic jaundice, congenital non-hemolytic jaundice, congenital non-heomlytic jaundice with kernicterus.
    Associated persons: Irwin Monroe Arias John Fielding Crigler Victor Assad Najjar Description: A familial form of congenital hyperbilirubinemia associated with severe disorders of the central nervous system and resembling kernicterus (degeneration of the basal ganglia). Other symptoms include jaundice of the skin, sclera, and mucous membrane. The syndrome is caused by an enzyme deficiency in the liver and faulty bilirubin conjugation. Both sexes affected. Presents with severe jaundice in the first few days after birth. Inheritance is autosomal dominant with incomplete penetration and varied expressivity. A deficiency of glucuronide formation was demonstrated by Irwin Monroe Arias in an anicteric father of two jaundiced children with a defect of hepatic glucuronyl transferase activity. This is sometimes referred to as Crigler-Najjar, type II. In Type I (above) death from kernicterus usually occurs within 15 months after birth. In Type II, which has been called Arias’ syndrome, the patient may survive to young adult life. Hyperbilirubinaemia in newborn in Crigler-Najjar syndrome is called Najjar-Crigler icterus.
