Islet cell antibodies (ICA), autoantibodies to glutamic acid decarboxylase (GAD) and HLA genotypes were examined in 31 patients with diabetes and a mitochondrial gene mutation located at base pair 3243 (mtDNA 3243 mutation). ICA was detected in 42% (13/31) of these patients compared to 0 of 90 among healthy control subjects. The ICA showed a "non-restricted" pattern of staining in all 13 ICA-positive patients. In a sensitive radioligand assay only 2 of 31 (6%) diabetic patients with the mutation were positive for both GAD65 autoantibodies and ICA, while the remaining 29 patients were GAD65 antibody negative. The ICA-positive patients had an increased frequency of the HLA-DQA1*0301 allele compared to control subjects (p < 0.05). Of the diabetic patients with the mutation 45% (14/31) had progressive clinical course of beta-cell failure. These results indicate that patients with an mtDNA 3243 mutation may develop islet autoimmunity associated with ICA and GAD autoantibodies. We hypothesize that the presence of HLA-DQA1*0301 in individuals with the mtDNA 3243 mutation increases the risk for diabetes and associated autoantibodies against islet cell antigens.
