Dubin-Johnson syndrome is a rare genetic disorder that affects the liver's ability to process bilirubin, a substance produced during the breakdown of red blood cells. This condition leads to an accumulation of conjugated bilirubin in the bloodstream, resulting in mild jaundice, which is a yellowing of the skin and eyes. The syndrome is usually inherited in an autosomal recessive pattern, meaning both parents must carry the gene for a child to be affected. Most individuals with Dubin-Johnson syndrome lead normal lives without significant health issues, and the condition is often discovered incidentally during routine blood tests.
