Coinheritance of these polymorphisms with previously identified risk alleles in Toll-like receptor 2 and TIRAP was associated with an additive risk of tuberculosis susceptibility.
Humans that are heterozygous for the common S180L polymorphism in the Toll-like receptor (TLR) adaptor Mal (encoded by TIRAP) are protected from a number of infectious diseases, including tuberculosis (TB), whereas those homozygous for the allele are at increased risk.
Polymorphisms in TIRAP do not appear to be involved in childhood TB susceptibility in South Africa, but may play a role in determining occurrence of TBM.
The aim of this study was to investigate the relationship of <i>TLR1, TLR6, MYD88</i> and <i>TIRAP</i> polymorphisms with susceptibility to latent tuberculosis infection (LTBI) and tuberculosis (TB).
These results support the influence of TIRAP (MAL) S180L polymorphism on TB and indicate that TB and SLE might share a common immunogenetic pathway in the innate immune response.

To test common and rare TLR variants involved in susceptibility or resistance to infection with Mycobacterium tuberculosis we screened the exons of the genes encoding TLR 1, 2, 4, and the adaptor molecule TIRAP in more than 4500 tuberculosis (TB) cases and controls from Ghana.
We investigated all the single-nucleotide polymorphisms (SNPs) within the TIRAP exon 5 in a case-control study of 212 patients with tuberculosis and 215 controls in a Chinese population.
