Genetic map of seven polymorphic markers comprising a single linkage group on rat chromosome 5.
Seven polymorphic markers comprising a single linkage group were assigned to rat Chromosome (Chr) 5 by linkage analysis of the progeny of an F2 intercross of Fischer (F344/N) and Lewis (LEW/N) inbred rats. Three genes, alpha-L-fucosidase 1 (FUCA1), mitochondrial superoxide dismutase (SOD2), and glucose transporter (GLUT1), were mapped by restriction fragment length polymorphism (RFLP) analysis. Two genes, glucose transporter (GTG3) and elastase II (ELAII), one pseudogene for alpha tubulin (TUBAPS), and one sequence related to the 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase gene (PFKFBP1-related sequence) were mapped by simple sequence repeat (SSR) polymorphism analysis. The loci are in the following order: SOD2, GTG3/GLUT1, FUCA1, ELAII/PFKFBP1-related sequence, and TUBAPS. This linkage group covered 68.3 cM of rat Chr 5. The SSR markers were highly polymorphic in 13 inbred rat strains (SHR/N, WKY/N, MNR/N, MR/N, LOU/MN, BN/SsN, BUF/N, WBB1/N, WBB2/N, ACI/N, LER/N, F344/N, and LEW/N). These markers, located on rat Chr 5, will be useful in genetic studies of inbred rats.
