However, for people with Chinese ethnicity, the CC genotype of TLR4-rs11536889 and TLR9-rs187084 (T > C) is associated with an increased risk of GC, while TLR4-rs1927911, rs10759931, and rs10116253 were found to confer protection against GC (Castaño-Rodríguez et al., 2013). This evidence concerns the gene TLR9 and gastric cancer.
