To test whether the higher TLR7 levels in the TLR7hi SLE group was associated with the TLR7 rs3853839 C/G SNP, we separated SLE patients into two groups: non-risk allele carriers (C/C for females and C for males) and G-risk allele carriers (G/G or C/G for females and G for males). Here, TLR7 is linked to systemic lupus erythematosus.
