  • Mô tả: To investigate the distribution of antigen-processing genes transporter associated with antigen processing (TAP), low molecular weight proteasome (LMP2) and HLA-DM in the Shanghai population and to explore the possible role of these genes in the genetic susceptibility to autoimmune diseases IgA nephropathy(IgAN) and multiple sclerosis(MS). Eighty normal Shanghai Chinese, 60 patients with IgAN and 21 patients with MS were randomly selected and genotyped for antigen-processing genes (TAP1, TAP2, LMP2, HLA-DMA and -DMB) using polymerase chain reaction-sequence specific oligonucleotide (PCR-SSO) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Two-locus linkage disequilibrium analysis was performed. Four TAP1, 6 TAP2, 2 LMP2, 3 DMA and 4 DMB alleles were observed. Statistically significant associations were found between TAP1B-TAP2A, TAP1B-LMP2H and TAP2D-HLA-DMA* 0101 (Pc < 0.01). There was no association between antigen-processing genes and either IgAN or MS. The polymorphisms of antigen-processing genes in this Shanghai population are similar to those observed in the other ethnic populations. No association was found between IgAN or MS and any antigen-processing genes tested in Shanghai population.
