Genomics meets genetics: towards a mutant map of the mouse

Phenotype-driven mutagenesis approaches in the mouse will deliver a vastly expanded mouse mutant resource and can be expected to lead to the identification of novel genes and pathways, enabling the emergence of new insights into mammalian gene function. In order for this goal to be realized, developments in genomics need to be harnessed to progress in mouse mutagenesis. We need firstly to generate a mutant map of the mouse, devising and employing rapid methods for the genetic mapping of the growing mouse mutant resource. Secondly, we need to be able to rapidly identify and assess candidate genes in the vicinity of the mapped mutations. Developments in mapping and genotyping technology are described that will potentially speed the construction of a rich mutant map of the mouse. In addition, the benefits of comparative sequencing of the human and mouse genomes are reviewed. The availability of both human and mouse genome sequences will underpin the evolution of a comprehensive and well annotated mammalian gene map that will significantly enhance our ability to move rapidly from mapped mutation to the identification of the underlying gene.
