In a 17 year-old male patient with Rotor's syndrome, hepatic glutathione S-transferase activity toward 1-chloro-2,4-dinitrobenzene reduced to about 0.2% of the mean activity of patients with other diseases. The activities toward sulfobromophthalein and 1,2-dichloro-4-nitrobenzene were low (44% and 47%, respectively, of those controls), but basically present. Bilirubin UDP-glucuronyltransferase activity in this Rotor's syndrome case was in the normal range.
