Recently Umeno et al. suggested that chronic enteropathy associated with SLCO2A1 gene mutation (CEAS), also known as chronic nonspecific multiple ulcers of the small intestine with SLCO2A1 mutation (CNSU), was a new clinical entity, distinct from Crohn’s disease and other known inflammatory bowel disorders such as intestinal Behcet’s disease and NSAIDs-induced enteropathy. The gene discussed is SLCO2A1; the disease is Crohn disease.
