BACKGROUND Single-nucleotide polymorphisms(SNPs)of the serotonin type 3 receptor subunit(HTR3)genes have been associated with psychosomatic symptoms,but it is not clear whether these associations exist in irritable bowel syndrome(IBS).AIM To assess the association of HTR3 polymorphisms with depressive,anxiety,and somatization symptoms in individuals with *** In this retrospective study,623 participants with IBS were recruited from five specialty centers in Germany,Sweden,the United States,the United Kingdom,and ***,anxiety,and somatization symptoms and sociodemographic characteristics were *** functional SNPs—HTR3A c.-42C>T,HTR3B c.386A>C,HTR3C c.489C>A,and HTR3E c.*76G>A—were genotyped and analyzed using the dominant and recessive *** also performed separate analyses for sex and IBS *** scores were calculated as the number of minor alleles of the SNPs *** impact of HTR3C c.489C>A was tested by radioligand-binding and calcium influx *** Depressive and anxiety symptoms significantly worsened with increasing numbers of minor HTR3C c.489C>A alleles in the dominant model(F_(depressive)=7.475,P_(depressive)=0.006;F_(anxiety)=6.535,P_(anxiety)=0.011).A higher SNP score(range 0-6)was linked to a worsened depressive symptoms score(F=7.710,P-linear trend=0.006)in *** potential relevance of the HTR3C SNP was corroborated,showing changes in the expression level of 5-HT3AC variant *** We have provided the first evidence that HTR3C c.489C>A is involved in depressive and anxiety symptoms in individuals with *** SNP score indicated that an increasing number of minor alleles is linked to the worsening of depressive symptoms in IBS.
