In Dubin-Johnson(autosomal recessive) and Rotor(possibly autosomal dominant) syndromes there are defects in bilirubin handling in the liver.there is conjugated hyperbilirubinaemia. prognosis is good in both. In the Dubin -Johson syndrome a mutation in the cMOAT tranpsorter gene has recently been discribed. The liver is black owing to melanin deposition.
