Association Between Toll-like Receptor 4 and Inflammatory Bowel Disease

Abstract

Haplotype analysis shows that TLR4 is associated with both CD and UC. The Asp299Gly and Thr399Ile variants do not show an association with CD, UC, or IBD as a group, indicating that these polymorphisms are likely not the causal ones. We propose that the 2 polymorphisms are in linkage with (the) disease susceptibility variant(s) located elsewhere on TLR4.
