PURPOSE: Toll-like receptor 2 (TLR2) is a transmembrane receptor that mediates immune responses to exogenous and endogenous ligands, and interacts with heat-shock proteins, which are reportedly involved in normal tension glaucoma (NTG). We investigated whether TLR2 polymorphisms are associated with NTG. METHODS: 200 Japanese patients with NTG and 128 healthy Japanese controls were recruited. We genotyped five single-nucleotide polymorphisms (SNPs) in the TLR2 gene and assessed the allele and haplotype diversities between cases and controls for all SNPs. RESULTS: No significant differences in the frequency of TLR2 alleles and haplotypes in the NTG cases were detected, compared with the controls. CONCLUSIONS: Our study showed no evidence for an association between TLR2 polymorphisms and NTG. TLR2 polymorphisms may not play an important role in NTG pathogenesis in the Japanese population.
