The antibody is specific to GAD2.
GAD65 (glutamic acid decarboxylase-65) are present in autoimmune disorders such as insulin-dependent (type1) diabetes mellitus (IDDM), stiff man syndrome and polyendocrine autoimmune disease. Auto-antibodies to GAD65 are present in 60-70% of individuals with newly diagnosed IDDM and thus are important markers for disease activity. These auto-antibodies usually recognize conformation-dependent regions on GAD65 and rarely bind to the second isoform, GAD67. Auto-antibodies to GAD67 are found in only 15% of recent-onset IDDM patients and most of this binding can be blocked with GAD65, suggesting shared epitopes between the two isoforms of GAD.
