Abstract:
Objective To detect TRAF1 gene single nucleotide polymorphism in Han population ,and analyze its association with increased risk of rheumatoid arthritis (RA) in Han people. Methods The study group was comprised with 100 healthy Han subjects and 100 Han RA patients. Six SNPs was detected by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOFMS), and the result was analyzed by Haploview software. Fisher's exact test and χ2 test were used for statistical analysis.Results The rs4836834 A/A, A/T, T/T allele frequencies of RA group were 22.22%, 49.49%, 28.28% respectively. The rs4836834 A/A, A/T, T/T allele frequencies of healthy control group were 28.57%, 30.61%,40.82% respectively. There was significant difference (P<0.05) of rs4836834 between Hah patients with RA and healthy controls. For other five sites, including rs10818488, which had been reported to be associated with increased risk of Caucasians RA patients, there was no significant difference (P>0.05) between RA group and the control group. The linkage disequilibrium and haplotype frequency analysis results showed that there was strong linkage disequilibrium between rs7021049 and rs7021880, rs7021049 and rs4836834, rs7021880 and rs4836834, but there was no significant difference between RA group and the control group in the haplo-type frequencies of the three classes of linkage disequilibrium. Conclusion TRAF1 gene may be a susceptible gene associated with Han RA people, but its single nucleotide polymorphisms and performance may be different between Caucasians and Han people.
