Genetic susceptibility to inflammation and colonic transit in lower functional gastrointestinal disorders: preliminary analysis.

ABSTRACT:

Background

Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) coexist in some patients. We observed an association between Crohn's disease (CD) candidate gene TNFSF15 and IBS symptom phenotype. Three genes (TLR9, IL6, and CDH1) have been associated with postinfectious (PI)-IBS. Our aim was to preliminarily assess association between 30 susceptibility loci for CD, three genes associated with PI-IBS, and PARM1, with colonic transit in lower functional gastrointestinal disorders (FGID).

Methods

A cohort of 665 persons was assembled in previous studies. TaqMan assay was used for all single nucleotide polymorphisms (SNPs) associated with the loci of interest. Data were analyzed for univariate associations with symptoms phenotype and colonic transit (nominal P val
