Autoantibodies to a 128-kd Synaptic Protein in Three Women with the Stiff-Man Syndrome and Breast Cancer

Abstract
The stiff-man syndrome is a rare disease of the central nervous system characterized by progressive rigidity of the body musculature. Autoantibodies directed against glutamic acid decarboxylase are present in about 60 percent of patients with the syndrome. In this group, there is a striking association of the stiff-man syndrome with organ-specific autoimmune diseases, primarily insulin-dependent diabetes mellitus.
