Susceptibility to sporadic inclusion body myositis (sIBM) in Caucasians has been consistently associated with alleles of the major histocompatibility complex (MHC) 8.1 ancestral haplotype (AH) (defined by HLA-B*0801 and HLA-DRB1*0301). In this study recombination mapping was utilised to further refine the known 8.1AH susceptibility region near HLA-DRB1*0301. Caucasian sIBM patients carrying part of the 8.1AH were genotyped for a selection of 8.1AH-haplotypic polymorphisms. A common 8.1AH-specific susceptibility region was defined, spanning 172 kb and encompassing three genes — HLA-DRB3, HLA-DRA and BTNL2. It is thus likely that 8.1AH-derived susceptibility to sIBM originates from at least one of these genes.
