Dubin-Johnson syndrome


Definition:

Dubin-Johnson syndrome is a disorder passed down through families (inherited) in which a person has mild jaundice throughout life.

Causes:

Dubin-Johnson syndrome is a very rare genetic disorder. In order to inherit the condition, a child must get a copy of the defective gene from both parents.

The syndrome interferes with the body's ability to move a chemical called bilirubin from the liver. Bilirubin is produced when the liver breaks down worn out red blood cells. It normally moves through the bile produced by the liver and into the bile ducts, past the gallbladder, and into the digestive system.

When bilirubin is not properly processed, it builds up in the bloodstream and causes the skin and the whites of the eyes to turn yellow (jaundice). Severely high levels of bilirubin can damage the brain and other organs.

People with Dubin-Johnson syndrome have lifelong mild jaundice that may be made worse by:

  • Alcohol
  • Birth control pills
  • Environmental factors that affect the liver
  • Infection
  • Pregnancy
Symptoms:

Mild jaundice, which may not appear until puberty or adulthood, is usually the only symptom of Dubin-Johnson syndrome.

Exams and Tests:

The following tests can help diagnose this syndrome:

Treatment:

No specific treatment is required.

Outlook (Prognosis):

The outlook is very positive. Dubin-Johnson syndrome generally does not shorten a person's lifespan.

Possible Complications:

Complications are unusual, but may include the following:

  • Reduced liver function
  • Severe jaundice
When to Contact a Medical Professional:

Call your health care provider if any of the following occurs:

  • Jaundice is severe
  • Jaundice gets worse over time
  • You also have abdominal pain or other symptoms (which may be a sign that another disorder is causing the jaundice)
Prevention:

Genetic counseling may be helpful for people who wish to have children and have a family history of Dubin-Johnson syndrome.
