About Crigler-Najjar syndrome type 1
What is Crigler-Najjar syndrome type 1?
Crigler-Najjar syndrome type 1 is a rare inherited disorder that affects the liver and causes a buildup of bilirubin in the body. It is caused by a deficiency of the enzyme glucuronyl transferase, which is responsible for breaking down bilirubin. Symptoms of Crigler-Najjar syndrome type 1 include jaundice, dark urine, light-colored stools, and an enlarged liver. Treatment typically involves phototherapy and, in some cases, a liver transplant.
What are the symptoms of Crigler-Najjar syndrome type 1?

This mutation results in a deficiency of the enzyme, leading to an accumulation of bilirubin in the body and the symptoms associated with the syndrome.
What are the treatments for Crigler-Najjar syndrome type 1?
