Abstract
AIM: To investigate the relationship between transient receptor potential vanilloid 1 (TRPV1) gene polymorphism and irritable bowel syndrome (IBS).
METHODS: Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and direct sequence analysis were used to comparatively analyze the polymorphism of the TRPV1 gene in patients with IBS (n = 73) fulfilling the Rome III criteria and healthy controls (n = 65).
RESULTS: A total of three genotypes were detected in IBS patients and healthy controls: CC, CT and TT. The frequencies of CC genotype and C allele in IBS patients were significantly higher than those in healthy controls (genotype: χ2 = 6.858, P = 0.032; allele: χ2 = 4.174, P = 0.041). A significant difference was found in TRPV1 gene polymorphism between IBS and healthy controls (P < 0.05).
CONCLUSION: The TRPV1 gene polymorphism is associated with the development of IBS. The presence of CC genotype and C allele probably increases the susceptibility of individuals to IBS. TRPV1 may be a novel therapeutic target for IBS.
