In general, fecal calprotectin (CALP) correlated more closely with the simple endoscopic score for Crohn’s disease (SES-CD) than C-reactive protein (CRP) levels, white blood cell (WBC) counts, and Crohn’s Disease Activity Index (CDAI) (Schoepfer et al., 2010). Here, KCNIP4 is linked to Crohn disease.
