Haptoglobin phenotypes were studied by a polyacrylamide gel electrophoresis on 200 blood donors and 105 patients with liver cirrhosis, of which 79% belonged to non-alcoholic etiology. Though no difference of haptoglobin types could be found between blood donors with positive and negative hepatitis B antigen, the cirrhois patients had an excess haptoglobin gene 1. The patients with haptoglobin gene 1 were associated with severe liver dysfunction. Since the family pedigrees of the patients with type 1--1 excluded individuals with type 2--2, the phenotypes seemed to be stable in the cirrhotic process. The possibility that the haptoglobin 2 gene offered resistence to the non-alcoholic cirrhosis was discussed.
