To test the possible role of TLRs in the development of T1DM, we studied different SNPs of TLR2 (N199N, S450S, R677W, and R753Q) and TLR4 (D299G, T399I, and S400N) in Basque families with T1DM.
Our data indicate that Asp299Gly and Thr399Ile genotypes of the TLR4 gene are associated with reduced prevalence of diabetic neuropathy in type 2, but not in type 1, diabetes.
