HLA-DR 67FLEDR71, especially 38V-67FLEDR71 sequence (carried on DRB5*0102 in linkage disequilibrium with DRB1*1502, DRB1*0802, DRBI*1101), showed the strongest association with anti-topo I response (46% vs 16% in controls; Pcorr = 0.001), and 38L-67FLEDR71 group alleles were not associated with anti-topo I response. Anti-topo I response was not significantly associated with HLA-DQB1 alleles in Koreans. There were only 3 ACA positive patients, and all patients had DRB1*1501 and DQB1*0602 as heterozygotes. Anti-U1 RNP occurred at a high frequency (63%) among patients with overlap syndrome, and was not associated with HLA-DR or DQ genes. Among anti-topo I negative patients, diffuse and limited subtypes of SSc were significantly associated with DRB1*0803 (47% vs 15% in controls; Pcorr < 0.05) and DRB1*1501 (50% vs 17% in controls; Pcorr < 0.01), respectively. These HLA associations have not been reported in other ethnic groups and possible associations with certain autoantibody subsets remain to be confirmed.ConclusionHLA-DR gene has a primary association with anti-topo I response, and HLA-DR 38V-67FLEDR71 group alleles including DRB5*0102 (in linkage disequilibrium with DRB1*1502) show the strongest association with anti-topo I response in Korean patients with SSc."xsd:string |
