Review Date:
12/05/2024 Anti-soluble liver antigen antibodies are detected in 10-30% of patients with type 1 autoimmune hepatitis (AIH), but not in patients with type 2 AIH, primary sclerosing cholangitis or primary biliary cirrhosis. The antibody is directed against a UGA suppressor tRNA-associated protein. In some patients with AIH, this antibody may be the only autoantibody detected by current assays.
