Assignment of 204 genes localized on HSA17 to a porcine RH (IMpRH) map to generate a dense comparative map between pig and human/mouse.
Bi- and uni-directional chromosome painting (ZOO-FISH) and gene mapping have revealed correspondences between human chromosome (HSA) 17 and porcine chromosome (SSC) 12 harboring economically important quantitative trait loci. In the present study, we have assigned 204 genes localized on HSA17 to SSC12 to generate a comprehensive comparative map between HSA17 and SSC12. Two hundred fifty-five primer pairs were designed using porcine sequences orthologous with human genes. Of the 255 primer pairs, 208 (81.6%) were used to assign the corresponding genes to porcine chromosomes using the INRA-Minnesota 7000-rad porcine x Chinese hamster whole genome radiation hybrid (IMpRH) panel. Two hundred three genes were integrated into the SSC12 IMpRH linkage maps; and one gene, PPARBP, was found to link to THRA1 located in SSC12 but not incorporated into the linkage maps. Three genes (GIT1, SLC25A11, and HT008) were suggested to link to SSC12 markers, and the remaining gene (RPL26) did not link to any genes/expressed sequence tags/markers registered, including those in the present study. A comparison of the gene orders among SSC12, HSA17, and mouse chromosome 11 indicates that intra-chromosomal rearrangements occurred frequently in this ancestral mammalian chromosome during speciation.
