A numerical difference was also observed for TLR9 (rs5743836), where the alternative G allele both in heterozygous (AG) or homozygous states (GG) was apparently associated with CMV infection (cumulative incidence rates of 64.4% and 66.7%, respectively) compared to the AA genotype (51.7%), although the difference did not reach statistical significance (P-value = 0.256). The gene discussed is TLR9; the disease is cytomegalovirus infection.
