The results of our study demonstrated that the G allele of the Asp299Gly polymorphism of the TLR4 gene is associated with increased risk of cardiovascular disease and diabetic retinopathy in type 2 diabetes patients.
Two specific polymorphisms of toll-like receptor 4 (TLR4; Asp299Gly and Thr399Ile) have recently been identified either as candidate protector genes against DM2 and associated neuropathy or risk alleles for the manifestation of diabetic retinopathy.
In conclusion, our results suggest an association between the Asp299Gly</span> polymorphism of the TLR4 gene and early onset of DR</span> in the DM2 patients.
