Crigler-Najjar syndrome

Genetic counseling is recommended for prospective parents with a family history of Crigler-Najjar syndrome.

Individuals with Crigler-Najjar syndrome develop hyperbilirubinemia in the absence of hemolysis.

Crigler-Najjar syndrome is a very rare inherited disorder in which bilirubin (a substance made by the liver) cannot be broken down.

An example is Crigler-Najjar syndrome.

People with Crigler-Najjar syndrome often have a genetic defect known as a point mutation: one base pair that is either incorrect or missing.

One 10-year-old girl with Crigler-Najjar syndrome type I was successfully treated by hepatocyte transplantation.

Crigler-Najjar syndrome occurs when the enzyme that normally converts bilirubin into a form that can easily be removed from the body does not work correctly.

Childs studied the genetics of adrenal hyperplasia, Crigler-Najjar syndrome, and propionic acidemia.

In the condition, Crigler-Najjar syndrome, a substance called bilirubin, a waste product from the destruction of worn-out red blood cells, builds up in the body.

The year was 1999, and the disease was Crigler-Najjar syndrome, a liver-enzyme deficiency that allows a lethal buildup of bilirubin in the blood.

The inheritance pattern of Crigler-Najjar syndrome type II has been difficult to determine but is generally considered to be autosomal recessive.

More severe types of glucuronyl transferase disorders like Crigler-Najjar syndrome (types I and II).

The hallmark finding of Crigler-Najjar syndrome is persistent yellowing of the skin, mucous membranes and whites of the eyes (jaundice).

In Crigler-Najjar syndrome and Gilbert syndrome, routine liver function tests are normal, and hepatic histology usually is, too.

Crigler-Najjar syndrome or CNS is a rare disorder affecting the metabolism of bilirubin, a chemical formed from the breakdown of red blood cells.

A Difficult Disease Frustration For Patients Dr. Morton first encountered Amish children with Crigler-Najjar syndrome in 1991.

Phenobarbital is occasionally prescribed in low doses to aid in the conjugation of bilirubin in patients suffering from Crigler-Najjar syndrome (Type II).

Autosomal recessive knockouts of UDP-glucuronyl-transferase itself can lead to Crigler-Najjar Syndrome and elevations of unconjugated bilirubin.

More specifically, amniotic epithelial cells have been used in the past to treat genetic liver diseases such as ornithine transcarbamylase deficiency, familial hypercholesterolemia, and Crigler-Najjar Syndrome.

A defect in the UGT1A1-gene, also linked to Crigler-Najjar syndrome and Gilbert's syndrome, is responsible for the congenital form of Lucey-Driscoll syndrome.

The homozygous Gunn rat, which lacks the enzyme uridine diphosphate glucuronyltransferase (UDPGT), is an animal model for the study of Crigler-Najjar syndrome.

Most cases of Crigler-Najjar syndrome are inherited as autosomal recessive traits and are due to errors or disruptions (mutations) of the UGT1 gene located on chromosome 2.

His patients think of him in another way: "He is a gift to us," said Miriam Martin of Mifflinburg, Pa., whose three young children are all under his care for Crigler-Najjar syndrome.

One reason the researchers chose Crigler-Najjar syndrome as a test case for the treatment is that if it works, the results will be easy to detect: the children should become less jaundiced, and their bilirubin levels, measured by a simple blood test, should fall.

Crigler-Najjar syndrome, type I is associated with mutation(s) that result in a complete absence of normal UDPGT enzyme, which causes a severe hyperbilirubinemia with levels of total serum bilirubin from 20 to 45 mg/dL.
