| abstractText | A genetic map of nine loci defined by polymorphic DNA markers was created using a single cross of F344/N and LEW/N rats. The markers contained polymorphic simple sequence repeats identified in five genes, renin (Ren), cardiac troponin T (Tnnt3), synaptotagmin (Syt2), Na+,K(+)-ATPase catalytic subunit (Atp1a2), and the Asp-, Gly-, Glu-, and Leu-tRNA gene cluster (Trnegl), as well as four anonymous DNA segments. Analysis of the segregation of the alleles of these markers in F2 intercross progeny of F344/N and LEW/N rats indicated the following locus order and distances between pairs of loci: D13N1-5 cM-Ren-1 cM-Tntt3-0 cM-Syt2-12 cM-D13N2-25 cM-Atp1a2-0 cM-Trnegl-7 cM-D13N3-4 cM-D13N4. Three of the loci, Ren, Trnegl, and Atp1a2, have previously been assigned to rat chromosome 13. Except for Ren, none of the loci have previously been mapped by linkage analysis. The markers for these loci were characterized in a total of 13 inbred rat strains (F344/N, LEW/N, LOU/MN, WBB1/N, WBB2/N, MR/N, MNR/N, ACI/N, SHR/N, WKY/N, BN/SsN, BUF/N, and LER/N) and were found to be highly polymorphic, with two to eight alleles detected for each marker. These markers expand the genetic map of the rat and should be valuable tools for future genetic studies. An examination of human and mouse comparative map information for all loci assigned to rat chromosome 13 shows significant synteny conservation with the q arm of human chromosome 1 and the distal portion of mouse chromosome 1. |
