Abstract:
Objective To investigate the correlation between single nucleotide polymorphisms (SNP) of gene interleukin-23 receptor (IL-23R) rs1004819, rs1495965, rs1884444, rs2201841,rs6677188, rs7517847, rs7530511, rs10489629, rs10889677 and rs11209026 with susceptibility of inflammatory bowel disease (IBD) in Han population of Jiangsu province in China. Methods The gene polymorphism in 134 healthy volunteers, 135 cases of ulcerative colitis(UC) and 43 cases of Crohn's disease(CD) were detected with SNaPshot. Experimental data were analyzed with SPSS 17.0 software. Results In UC, genotype frequency of CC and CT on rs7530511 was 99.26％ (134/135)and 0.74％(1/135), allele frequency of C and T was 99.63％(269/270)and 0. 37％(1/270). While in normal controls, which were 94.03％(126/134), 5.97％(8/134), 97.01 ％(260/268)and 2.99％(8/268)respectively. Compared genotype frequency of these two group, P value was 0. 040 (OR＝0.118、95％CI:0.014～0.953). Compared allele frequency of these two group, P value was 0. 043 (OR＝0.121、95％CI:0.015～0.973). In wild type and mutation type UC patients, the age distribution was different, more young patients in mutation type while more middle-aged patients in wild type, P value was 0.032 and 0.001 respectively. Most UC patients of rs6677188 AT type were in remission under endoscope (P＝0.032). Conclusion The mutation of IL-23R rs7530511 may be a protective factor of UC. The polymorphism of rs6677188 was associated with the age of patients and the remission under endoscope.
