Abstract
ObjectiveTo investigate the role of eight locus polymorphisms of tumor necrosis factor receptor associated factor 2 (TRAF2) and TRAF5 gene and their interaction in the susceptibility to ankylosing spondylitis (AS) in Chinese Han population.MethodsEight single nucleotide polymorphisms (SNPs) (rs3750511, rs10781522, rs17250673, rs59471504, rs6540679, rs12569232, rs4951523, rs7514863) of TRAF2 and TRAF5 gene were genotyped in 673 AS patients and 687 controls.ResultsThe SNPs of TRAF2 and TRAF5 does not indicate a correlation with the susceptibility of AS in Chinese Han population. Genotype frequencies of rs3750511were statistically significant in females between patients and controls. The genotype frequencies of rs12569232 and allele frequencies of rs3750511were statistically significant between groups of different diseases activity. One three-locus model, TRAF2 (rs10781522, rs17250673) and TRAF5 (rs12569232), had a maximum testing accuracy of 52.67% and a maximum cross-validation consistency (10/10) that was significant at the level of P=0.0001, after determined empirically by permutation testing. As to environmental variables, only marginal association was found between sleep quality and AS susceptibility.ConclusionTRAF2 rs3750511 polymorphism may be associated with the susceptibility and severity of AS. Besides, the interaction of TRAF2 and TRAF5 genes may be associated with AS susceptibility, but many open questions remain.
