Association of CCK1 Receptor Gene Polymorphisms and Irritable Bowel Syndrome in Korean

摘要

IntroductionCholecystokinin (CCK) belongs to a group of endogenous molecules known as brain-gut neuropeptides and functions as a neuropeptide as well as a gut hormone. It remains unclear whether genetic variation of the CCK receptor plays a role in irritable bowel syndrome (IBS). The aim of this study was to determine and compare the allele and genotype frequencies of the CCK1 receptor polymorphisms between healthy controls and patients with IBS.
