Various genes that mapped to the distal end of Chromosome (Chr) 10 were considered as possible candidates for the mouse pygmy (pg) locus. Probes derived from Ifg, Gli, Mdm1, Mdm2 and Mdm3 (Mdm2 and Mdm3 are genes that are coamplified with Mdm1 on the same double minute chromosomes in 3T3DM cells) were used for Southern analysis of DNA from wild-type mice and various pg mutants. In addition, the chromosomal locations of Ifg, Gli, Mdm1, Mdm2, and Mdm3 were determined by interspecific backcross analysis with progeny derived from matings of [(C57BL/6J x Mus spretus)F1 x C57BL/6J] mice. The mapping data indicate that the Mdm loci are linked to each other and to Ifg, pg, and Gli in the distal region of mouse Chr 10. Both the mapping data and the Southern analysis confirm that mdm1, Mdm2, Mdm3, Ifg, and Gli are distinct from pg.
