Association Of Interleukin-23 Receptor Gene Rs1343151 Single Nucleotide Polymorphism With Ankylosing Spondylitis

Objective To investigate the association between interleukin-23 receptor (IL-23R) gene rs1343151 single nucleotide polymorphism and Ankylosing Spondylitis (AS) in Chinese han patients.Methods The genotypes of IL23R SNP was detected in 104 Chinese AS patients and 95 ethnically matched controls blood donors by TaqMan probe assays. The allele and genotype frequencies and risk factors of AS were analyzed by Chi-square test in both groups.Results The rs1343151 genotypes in the AS patients consisted of homozygote C/C (90.4%),C/T (9.6%), while The rs1343151 genotypes in the controls were composed of C/C (91.6%),C/T (8.4%). No significant difference was found in the distribution of rs1343151 genotypes between these two groups(χ2=0.086 P>0.05).The frequency of rs1343151 allele in AS patients was also not significantly increased, compared with the control group(χ2=0.082 P>0.05).Conclusion There may be no association between the IL-23R gene rs1343151 SNP and Ankylosing Spondylitis in Chinese Han population.
