In a study aiming at understanding the role of two TLR2 SNPs in the susceptibility to infection and contribution to the development of the tubal pathology in Dutch women, Karimi et al. [37] revealed a statistically significant association between certain TLR2 haplotypes and protection from tubal pathology and development of the late inflammatory complications (the absence of TLR2 is associated with an increase in the severity of the Chlamydia infection). The gene discussed is TLR2; the disease is chlamydia infectious disease.
