GAD65Abs in patients diagnosed with T1D predominantly recognize an epitope shared with monoclonal GAD65Ab b96.11 [17], whereas GAD65Abs in patients with neuromuscular autoimmune diseases recognize epitopes shared with b78 and N-GAD65-Ab [27], those in patients diagnosed with LADA recognize the DPD-defined epitope [17] and those in healthy individuals recognize the DPA-defined epitope [17]. The gene discussed is GAD2; the disease is latent autoimmune diabetes in adults.
