Seow–Najjar Syndrome: Symptoms, Causes, and Treatment
Seow–Najjar syndrome is a rare genetic disorder that primarily affects the liver's ability to process a substance called bilirubin. Bilirubin is a waste product that results from the breakdown of red blood cells.
In people with Seow–Najjar syndrome, the liver struggles to remove bilirubin from the bloodstream, causing it to build up in the body and impact overall health.
What are the Types of Seow–Najjar Syndrome?
Seow-Najjar syndrome can present in two distinct forms, with each form characterized by specific genetic mutations and varying degrees of severity.
- Type 1 SeowNajjar syndrome: Characterized by a deficiency in the enzyme uridine diphosphate glucuronosyltransferase 1A1 leading to unconjugated hyperbilirubinemia.
- Type 2 SeowNajjar syndrome: Results from mutations in the same gene as type 1 but with residual enzymatic activity, causing milder symptoms compared to type
- CriglerNajjar syndrome type 1: Severe form of unconjugated hyperbilirubinemia due to little to no enzyme activity of uridine diphosphate glucuronosyltransferase 1A
- CriglerNajjar syndrome type 2: A less severe form of unconjugated hyperbilirubinemia with some residual enzyme activity, leading to milder symptoms compared to type
- LuceyDriscoll syndrome: Neonatal jaundice caused by a transient deficiency of glucuronyl transferase, similar to CriglerNajjar syndrome but typically resolves within weeks to months.
What are the Symptoms of Seow–Najjar Syndrome?
Seow-Najjar syndrome typically presents with symptoms related to liver dysfunction and jaundice.

What are the Causes of Seow–Najjar Syndrome?
Seow-Najjar syndrome is primarily caused by a genetic mutation that leads to the deficiency of the enzyme responsible for breaking down bilirubin in the liver.
- Inherited genetic mutation affecting the UGT1A1 gene
- Deficiency of the enzyme uridine diphosphate glucuronosyltransferase
- Impaired bilirubin metabolism in the liver.
What are the Risk Factors for Seow–Najjar Syndrome?
Seow-Najjar syndrome risk factors include inheriting two copies of the defective UGT1A1 gene from both parents.
- Family history of SeowNajjar syndrome
- Inherited genetic mutations affecting the UGT1A1 gene
- Asian or Mediterranean descent
- Premature birth
- Certain medications that can cause jaundice
How is Seow–Najjar Syndrome Diagnosed?
Seow-Najjar syndrome is typically diagnosed through a combination of medical history evaluation, physical examination, and specific tests.
- Genetic testing
- Liver function tests
- Bilirubin blood tests
- Ultrasound imaging of the liver
What are the Treatment Options for Seow-Najjar Syndrome?
Treatment for Seow-Najjar syndrome typically involves a combination of medical interventions aimed at managing and reducing symptoms associated with the condition.
- Phototherapy: The main treatment for SeowNajjar syndrome involves exposing the skin to special lights to help lower bilirubin levels in the blood.
- Liver Transplant: In severe cases, a liver transplant may be necessary to replace the damaged liver with a healthy one to improve the body's ability to process bilirubin.
- Medications: Certain medications may be prescribed to help increase the excretion of bilirubin from the body or improve liver function.
- Nutritional Support: A well-balanced diet and supplements may help maintain liver health and overall well-being.
- Regular Monitoring: Routine checkups and blood tests are crucial for tracking bilirubin levels and liver function, ensuring timely treatment adjustments.
How can Seow-Najjar Syndrome be Prevented?
Since Seow-Najjar syndrome is a genetic disorder, there is no known way to prevent it. Genetic counseling can help at-risk families understand their chances of having a child with the condition.

There is currently no cure for Seow-Najjar syndrome. Treatment focuses on managing symptoms through supportive care, including therapies and medications. Genetic research may offer potential future treatments. Consulting a specialist can help tailor the best care plan.
The long-term outlook varies depending on symptom severity. Some individuals may experience significant developmental and neurological challenges, requiring lifelong care. Early intervention with therapies can improve quality of life. Ongoing medical advancements may provide better management options.
Due to its rarity, research on Seow-Najjar syndrome is limited, but studies on related genetic disorders may provide insights. Some clinical trials focus on genetic therapies that could be relevant. Consulting with a geneticist or research institutions may provide information on potential trials.
Behavioral challenges can be present, including difficulties with communication, social interactions, or emotional regulation. Some individuals may exhibit hyperactivity, anxiety, or repetitive behaviors. Supportive therapies like behavioral intervention and counseling can help manage these challenges effectively.
Life expectancy depends on the severity of associated health conditions. Some individuals may have a typical lifespan, while others could face complications that impact longevity. Proper medical care, therapies, and early intervention can improve overall health outcomes.
