Serotonin in the gastrointestinal tract. Genes and functional GI disorders: Abnormal immune regulation and low-grade inflammation in IBS: The IBS risk genes proposed so far are nonvalidated hits rather than true predisposing factors, and the studies conducted have been largely too underpowered to capture true association signals[ 38 ]. The reasons underlying the conflicting results yielded by genetic association studies, and especially in IBS, are discussed elsewhere[ 38 , 55 ].

Gastrointestinal microbiome signatures of pediatric patients with irritable bowel syndrome. This article is an open-access article which was selected by an in-house editor and fully peer-reviewed by external reviewers. These factors are genetic disposition, diet, the intestinal microbiota, and mucosal low-grade inflammation. Low-grade inflammation appears to play a role in the pathophysiology of a major subset of IBS, namely postinfectious IBS.
