1 Autoimmune DM is characterised by the presence of one or more islet-specific autoantibodies, including islet cell autoantibodies (ICA), insulin (IAA) and autoantibodies directed against the three major islet autoantigens - glutamic acid decarboxylase 65 (GADA), protein tyrosine phosphatase IA-2A and its isoform IA-2b/phogrin (IA-2bA).
