摘要: We investigated the polymorphic second exon of HLA-DPB1 and HLA-DRB1 genes, using in vitro DNA amplification by polymerase chain reaction (PCR) oligonucleotide hybridization 136 patients with early onset pauciarticular juvenile chronic arthritis (EOPA-JCA) 199 healthy controls. The analysis system revealed that most DRB1 alleles are not indifferent respect to susceptibility EOPA-JCA. There is a hierarchy susceptible (DRB1*08, DR5), "permissive" (DRB1*01), moderately "protective" (DR2, DRB1*04), (DRB1*07) alleles. In contrast, no could be shown for system. DPB1*0201 was found susceptible. relatively frequent DPB1*0402 DPB1*0401 seem indifferent. associations DPB1*0201, DR5, DRB1*08 independent each other: say they, brought about linkage disequilibrium. DR5 show evidence interaction pathogenesis Interaction seems likely between DRB1*08, or DR6 DRB1*08. strongest exists common DQ factor associated both Finally, we observed among various marker combinations, where risk developing EOPA-JCA increases number markers present an individual.
