TLR4 and Parkinson disease: Genetic variants of TLRs, including rs5743611 (p.R80T) in TLR1, rs5743708 (p.R753Q) in TLR2, rs4986790 (p.D299G) in TLR4, intronic and 5′untranslated region variants including rs1927911, rs1927914, and rs10116253 in TLR4, and rs5743810 (p.S249P) in TLR6, were genotyped, since these variants were reported to increase the risk of PD (Senhaji et al., 2014; Zhao et al., 2015).
