A recent announcement in Science describes the kickoff of NIH's Knockout Mouse Project.  This project is one part of a multiple aims to create a knockout mouse for every gene in the mouse genome.  Along the same theme as the Allen Brain Atlas, the goal is to get complete coverage of the mouse genome, and allow researchers to use the resources that are generated by centers coordinated in this effort.  It's exciting to have the ability to view gene expression patterns on a genome-wide scale now with the Allen Brain Atlas, and know that soon the knockout resources will also be available to reserchers for all these genes.
