For the TLR9 1174G/A SNP, the GA genotype was associated with higher risk of elevated liver enzyme levels and leukocytosis (OR 3.055; 95% CI 1.333–7.000; p = 0.008 and OR 2.412; 95% CI 1.143–5.088; p = 0.021, respectively), whereas the risk of these symptoms were decreased in patients with wild-type genotype (OR 0.370; 95% CI 0.164–0.836; p = 0.017 and OR 0.447; 95% CI 0.213–0.939; p = 0.034, respectively). The gene discussed is TLR9; the disease is Increased total leukocyte count.
