Crigler Najjar Syndrome affects fewer than 50 people in the United States and fewer than 200 people in the whole world. The condition is a metabolic disorder and is hereditary. It is caused by an enzyme deficiency in the liver which prevents bilirubin – a normal byproduct which results from the body’s natural disposal of red blood cells when the cells die – from being broken down in the blood as it should.

Blue light therapy is the standard treatment for this life threatening disorder.  More information at the links below.
