過(guò)敏性紫癜患兒T細(xì)胞受體保守域α鏈基因多態(tài)性研究
[Abstract]:Aim to investigate the relationship between T cell receptor conserved domain 偽 chain gene (TCRC 偽) 560C / T, 575A 偽 G polymorphism and the pathogenesis of (HSP) in Henoch-Schonlein purpura (Henoch-Schonlein purpura). Methods 36 children with Henoch-Schonlein purpura (Henoch-Schonlein purpura) and 60 normal children were studied with polymerase chain reaction-restriction endonuclease fragment length polymorphism (PCR-PFLP) combined with agarose gel electrophoresis. Polymorphism analysis of 575A/G locus gene. Results (1) there was no significant difference in the frequencies of three genotypes of CC,CT,TT at site-560of TCRC 偽 gene between purpura group and normal group (x2, 5.39, P0.05). The allele frequencies C and T of this locus were significantly different between purpura group and normal group (x2 / 4.69, P0.05). (2) there was no significant difference in the frequencies of AA,AG,GG genotypes at site-575 of TCRC 偽 gene between purpura group and normal group (x2? 1.07, P0.05). There was no significant difference in allele frequencies A and G between Henoch-Schonlein purpura group and normal group (x2? 1.01, P0.05). Conclusion (1) the polymorphism of TCRC 偽-560C/T gene may be associated with the occurrence of HSP. (2) there was no significant correlation between the polymorphism of TCRC 偽-575A/G gene and the occurrence of HSP.
