A person with Dubin Johnson syndrome has a rare inherited disorder that causes the buildup of bilirubin in the liver, resulting in episodes of mild jaundice.

Bilirubin is one of the by-products that result from the breakdown of hemoglobin, which carries oxygen in the bloodstream.

The episodes of jaundice are temporary and treatment is not required. Those with Dubin Johnson syndrome live normal lives and have a normal life expectancy.
