Abstract
Genetically determined resistance to flaviviruses in mice is a dominant trait conferred by alleles at a single autosomal locus designated Flv, but no gene products have been associated with this locus and the mechanism of resistance is not well understood. To further characterize this model of genetic resistance, we conducted mapping studies to determine the chromosomal location of Flv. Because of evidence suggesting that the Flv locus is on chromosome 5, three-point backcross linkage analyses were used to define the location of Flv relative to previously assigned chromosome 5 markers. The results confirm the chromosome 5 location of Flv and indicate a map position between the anchor loci rd and Gus-s. The chromosomal localization of Flv is the first step in the production of a detailed linkage map of the Flv region, which may open approaches to positional cloning of the resistance gene.
