Practicable approaches to targeted comparative mapping of rat chromosome regions: linkage mapping of five genes on rat chromosome 13

Abstract

We demonstrate feasible approaches to comparative mapping between the region near the renin locus on rat chromosome 13 and human chromosome 1q by assigning five additional genes as anchor loci. Base-substitution polymorphisms were sought in the 3'- and/or 5'-untranslated regions for subsequent development of PCR-amplified markers, which, in turn, could be used for either restriction fragment analysis or allele-specific PCR.
