Researchers are developing and testing novel gene therapy to cure Crigler-Najjar syndrome

Crigler-Najjar syndrome affects about one in a million people at birth. Because of a defective gene, these individuals lack an essential enzyme in their liver to eliminate bilirubin, a toxic bile pigment that accumulates in all body tissues causing jaundice and potentially leading to irreversible and lethal neurological damage.
