E80.5
Crigler-Najjar syndrome
Clinical Classification Guidelines
Medical Intelligence & Overview
Crigler-Najjar syndrome is a rare inherited disorder affecting the body's ability to process bilirubin, a yellow pigment formed during the breakdown of red blood cells. This condition can lead to severe jaundice, characterized by a yellowing of the skin and eyes, and in some cases, serious neurological complications. The syndrome is classified into two types, each with different severity levels and treatment options. Recognizing and managing this condition early is essential to prevent complications.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting the UDP-glucuronosyltransferase enzyme, which is responsible for processing bilirubin in the liver Inherited in an autosomal recessive pattern, meaning a person needs two copies of the mutated gene to develop the syndrome Type 1 Crigler-Najjar syndrome, caused by a complete deficiency of the enzyme Type 2 Crigler-Najjar syndrome, caused by a partial deficiency of the enzyme
Key Symptoms: Severe jaundice appearing within the first days of life Unusual lethargy or irritability Poor feeding and weight loss in infants Risk of neurological damage, such as kernicterus, if bilirubin levels are very high In some cases, symptoms may include seizures or developmental delays
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves blood tests to measure bilirubin levels and identify the type of Crigler-Najjar syndrome. Liver function tests and genetic testing can confirm the diagnosis. In newborns particularly, early testing is crucial for prompt management to prevent complications.
Treatment Protocols: Treatment strategies vary based on the severity of the syndrome. Common approaches include:
