Objective: The present study aims to investigate the relationship between genetic polymorphisms in HTR3A and HTR3E and diarrhea predominant irritable bowel syndrome (D-IBS) in a Chinese population. Methods: We enrolled 500 D-IBS patients and 500 age-and sex-matched healthy control subjects to detect the genotypes in HTR3A and HTR3B gene by using of PCR-RFLP method. Results: There were significant difference between the D-IBS patients and the health control subjects in the distribution of genotype and allele of rs1062613 in HTR3A gene. As regarding rs62625044 in HTR3E gene, we found there was a significant different between the case and the control group in the distribution of GA genotype and A allele in female but not in male. Conclusion: The present study suggested that there are associations of D-IBS risk with genetic polymorphisms in HTR3A and HTR3E.
