Methods In a two-stage, case –control study, we analyzed frequency MHC class I II haplotypes either transient or typing was performed microlymphocytotoxicity assays. analysis restriction-fragment–length polymorphisms (RFLPs), supplemented other techniques. Results first stage (the study up age 10 years), RFLP pattern 25-1, which includes allele HLA-DRB1*1302, found 58 218 (26.6 percen...
