Restriction endonuclease fragment length variations (RFLV) were detected in mice with DNA probes for myelin basic protein (Mbp), glucocorticoid receptor-1 (Grl-1), and Friend MuLV integration site-2 (Fim-2). RFLV of the Mbp gene were found in SacI restriction patterns, RFLV of the Grl-1 gene were found in EcoRV patterns, and RFLV of the Fim-2 were found in BglII patterns. A three-point backcross was carried out by the backcross mating (C57BL/KsJ-spm/spm x MOL-MIT)F1 males x C57BL/KsJ-spm/spm; spm is an autosomal recessive gene causing sphingomyelinosis. From the results, spm, Grl-1, Fim-2, and Mbp loci were mapped on chromosome 18, and the following order of genes is proposed, with distances between genes in parentheses: centromere--spm--(7.8 cM)--Grl-1--(7.8 cM)--Fim-2--(39.1 cM)--Mbp--telomere. All laboratory strains and two European subspecies (Mus mus domesticus and M. m. brevirostris) carry the Grl-1a, Fim-2a, and Mbpa alleles. In contrast, another wild subspecies from Europe (M. m. musculus) and some Asian subspecies (M. m. molossinus, Chinese mice of wild origin, and M. m. yamashinai) carry the Grl-1b, Fim-2b, and Mbpb alleles. Only castaneus strains carry the intermediate combination of the Grl-1b, Fim-2a, and Mbpb alleles.
