Clinical Significance
Beta-2-Glycoprotein 1 (also known as apolipoprotein H), is a cofactor in antiphospholipid antibody binding and is the critical antigen in the antiphospholipid antibody syndrome. The presence of high titer IgG/IgM beta-2-glycoprotein 1 antibodies is one criteria for the diagnosis of antiphospholipid antibody syndrome.
