Abstract Genome-wide association studies (GWAS) have identified over 300 loci associated with the inflammatory bowel diseases (IBD), but putative causal genes for most loci are unknown. We conducted a disease-focused expression quantitative trait loci (eQTL) analysis using colon tissue from 252 IBD patients. We hypothesized IBD tissue could uncover IBD-associated regulatory variation undetectable in non-IBD cohorts.

To validate a novel biomarker, airway impedance for extraesophageal disease. We prospectively recruited patients with respiratory symptoms undergoing combined endoscopy and direct laryngoscopy (DL) for the evaluation of symptoms. The DL was performed and videotaped for blinded scoring by three otolaryngologists and an impedance catheter was placed onto the posterior larynx to obtain measurements.
