Abstract:
Objective To investigate the association between ankylosing spondylitis (AS) in Han population from Hunan province of China and polymorphism located at the position nt587 in the tumor necrosis factor receptor Ⅱ ( TNFR Ⅱ ) gene.Methods Correlation analysis was performed in a case-control of 100 AS cases and 100 healthy control.The SNPs located in the TNFR Ⅱ gene ( TNFR Ⅱ nt587 ) was examined by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP).With the SPSS software,the relationship between AS and frequencies of genotype and alleles in TNFR Ⅱ nt587 were analyzed.Results There were 43 cases with TNFR Ⅱ nt587 T/T genotype,32 cases with TNFR Ⅱ nt587 T/G genotype and 25 cases with TNFR Ⅱ nt587 G/G genotype in the AS cases.While in the healthy control,there were 56 cases with TNFR Ⅱ nt587 T/T genotype,34 cases with TNFR Ⅱ nt587 T/G genotype and 10 cases with TNFR Ⅱ nt587 G/G genotype.At the same times,the allele frequencies of G in AS group was significantly higher ( x2 =8.734,P=0.003 ) than the control group (41.0％ vs.27.0％ ).The odds ratio in AS cases with TNFR Ⅱ nt587 G/G genotype was 3.256,which higher than those with G/G ( OR =1.226) genotype and T/T genotype compared the healthy control.Conclusion The study demonstrates that polymorphism within the TNFR Ⅱ at the position nt587 is associated with AS and TNFR Ⅱ nt587 G may play an important role in AS susceptibility,and TNFR Ⅱ nt587 G/G genotype may increase the sicken risk of AS in Hunan population.
