Core Tip
Core tip: Irritable bowel syndrome (IBS) is believed to result from interplay of several factors including hypersensitivity of the bowel, altered bowel motility, inflammation and stress. Familial aggregation of cases and twin studies underscore the genetic basis of IBS. Different researchers have studied several candidate genes but the evidence so far linking IBS to specific genes is inconsistent and weak. Genome wide association studies that can examine several common genetic variants are needed to design newer drugs and diagnostic methods.
