Altered body rhythmicity and deregulated clock gene expression may cause circadian disruption, which can lead to immune dysregulation and chronic inflammatory diseases. PERIOD3 (PER3) polymorphisms have been associated with circadian disruption and changed secretion of cytokines involved in chronic inflammation. Crohn's disease (CD) and ulcerative colitis (UC) are multifactorial diseases resulting from complex interaction among environmentalmicrobial factors and the intestinal immune system, triggering an abnormal immune response in genetically susceptible individuals. We evaluated the influence of a polymorphism of the clock gene PER3 on susceptibility and behavior of these inflammatory bowel diseases. The rs2797685 variant of the PER3 gene was assessed in 1082 CD and 972 UC patients, 754 of whom had been diagnosed
