Mouse H2 congenic intervals: analysis and use for mapping.
In this study we exploit the unique genetic resource of inbred mouse major histocompatibility complex (H2) congenic and recombinant strains to construct a high-resolution map of microsatellite loci in and around the H2 region, as well as an independent genetic map of other loci on mouse Chromosome (Chr) 17. Microsatellite loci were analyzed in 11 C57BL/10 (B10) strains to determine the size of the congenic interval in each. The length of the congenic interval found in each strain varied widely. Interestingly, the intervals were generally smaller than statistical expectations. However, the observed congenic intervals were still sufficiently long that these strains and probably wild-derived H2 congenics are an important source of genetic variability. The staggered ends of the various congenic intervals and the recombinants were used to construct the map. This map will be useful for physical cloning and to help localize novel genes. As evidence of the mapping application of congenic strains, locational information was derived about Trp53-ps and Stl.
