Rotor’s syndrome /rō″tərs/ , a rare condition of the liver inherited as an autosomal-recessive trait. It is similar to Dubin-Johnson syndrome but can be distinguished by the normal functioning of the gallbladder and lack of liver pigmentation. Jaundice occurs in childhood, caused by impaired biliary excretion. See also Dubin-Johnson syndrome, hyperbilirubinemia of the newborn.
