The accompanying figure. It was based on the previous year’s map, mapping data previously used for Lhr had been erroneously asso- which divided the 69 map units into bins and assigned positions of ciated with that locus, and the AXBXA RI data used for mapping genes and other markers using the Copeland-Jenkins, EUCIB, were no longer convincing, with LOD scores for linkage to any Jackson Laboratory, and MIT genetic mapping panels. Data from marker on Chr 14 being less than 1. Mutations are indicated by a the Seldin, Kozak and other mapping panels were integrated into T in column 6, and several genes on the chromosome are repre- this framework.

The Of the genes mapped on Chr 14, 81 have known counterparts positions of all genes were checked against flanking markers and in the human map. These are mainly found on five human chro- a number of loci were moved to eliminate ambiguities due to mosomes, 3, 8, 10, 13 and 14. Single loci are found on human integration of markers not typed in the same cross. chromosomes 21 (Vdac2) and X/Y (Il3ra). The ten loci that are There are a total of 856 entries, of which 108 are associated orthologous with human Chr 3p are all at the proximal end of Chr with the Tcra gene complex. The entries include 22 translocations, 14. The fifteen loci orthologous to human Chr 10q are found over 19 deletions, 3 inversions and 2 duplications. There are 73 new the same region of mouse Chr 14, from position 2.5 to position entries, of which 69 are localized on the chromosome and 4 are 15.5. The 23 loci syntenic with human Chr 14q span the region syntenic. These loci include 29 new named genes or related se- from position 12 to 22, including Tcra.
