Susceptibility to autoimmune orchitis is associated with an immune response (Ir) gene (now designated Orch-1) which was preliminarily shown to reside at or near the H-2D subregion of the major histocompatibility complex in the mouse (H-2). In this study, the role of H-2 in controlling both disease susceptibility and the phenotypic expression of infertility associated with autoimmune orchitis has been significantly extended. Of nine C57BL/10SnJ and three BALB/cAnN H-2 congenic strains, only those mice possessing the H-2d, H-2p haplotypes exhibited autoimmune orchitis accompanied by infertility. All other congenic strains, including those expressing the H-2 haplotypes v, q, b, s, r, f, and k were of the low responder phenotype. In addition, disease susceptibility was found to be inherited as a dominant trait in H-2 congenic F1 hybrid mice. In order to map the precise location of the Orch-1 locus within H-2, 32 intra-H-2 recombinant congenic strains possessing defined crossovers in various locations throughout the H-2 region were studied. The results of the analysis indicate that Orch-1 maps within the interval between the H-2S and H-2D regions. Our results also indicate that class II genes, i.e., A and E region-encoded genes, have little discernable effect in controlling disease susceptibility and resistance despite the fact that testicular lesions can be adoptively transferred with Ia-restricted CD4+ effector T cells. A comparison of the Orch-1 alleles with the genotypes of two additional markers which map within the H-2S/H-2D interval suggests the following gene order: H-2S--TNP-Ficoll--Orch-1--Tnfa--H-2D.
