The results were correlated to established scores of clinical, endoscopic and histologic disease activity (partial [pMS] and endoscopic [eMS] Mayo‐Score, ulcerative colitis endoscopic index of severity [UCEIS], histologic Nancy index) and/or biomarkers of inflammation (C‐reactive protein [CRP], fecal calprotectin). The gene discussed is CRP; the disease is ulcerative colitis.
