To the Editor: Irritable bowel syndrome (IBS) is a common, poorly understood gastrointestinal disorder. Although family and twin studies broadly support the existence of a genetic component of IBS risk (1), previous candidate gene association studies had limited capacity to identify novel genes. Genome-wide association studies (GWAS), which have revealed new risk genes for various complex diseases, have not yet been published for IBS.
