| Abstract: | TheLy-6 locus is now regarded as a gene complex consisting of at least five closely linked loci (Ly-6A-Ly-6E) whose polymorphic products are identified by monoclonal antibodies and distinguished by different tissue distributions.Ly-6 has been assigned by other investigators to chromosome (Chr) 9 (linked toThy-1 or to Chr 2. We report that theLy-6 gene complex, together with theXp-14 andGdc -1 loci, is situated on Chr 15 linked toGpt1. These new linkage data are derived from four sources: (1) three separate crosses that failed to demonstrate linkage ofLy-6 to eitherThy-4 on Chr 9 or to any of five genes present on Chr 2; (2) the NXSM recombinant inbred strains, which suggested the linkage ofLy-6 andXp-14 toGpt-1 on Chr 15; (3) severalGpt-1 andGdc-1 congenic strains that confirmed the assignment ofLy-6 andXp-14 to Chr 15; and (4) backcrosses that further confirmed the linkage ofLy-6, Gpt-1, Gdc-4, andXp-14, the probable gene order beingGpt-11/Ly-6 Xp-14-Gdc-1. |
