The first recorded knockout mouse was created by Mario R. Capecchi, Martin Evans, and Oliver Smithies in 1989, for which they were awarded the 2007 Nobel Prize in Physiology or Medicine. Aspects of the technology for generating knockout mice, and the mice themselves have been patented in many countries by private companies.
The Mouse Genetics Project (MGP) is a large-scale mutant mouse production and phenotyping programme aimed at identifying new model organisms of disease. [1] [2] [3] [4]Based at the Wellcome Trust Sanger Institute, the project uses knockout mice most of which were generated by the International Knockout Mouse Consortium.
The International Knockout Mouse Consortium (IKMC) is a scientific endeavour to produce a collection of mouse embryonic stem cell lines that together lack every gene in the genome, and then to distribute the cells to scientific researchers to create knockout mice to study.
The International Mouse Phenotyping Consortium (IMPC) is an international scientific endeavour to create and characterize the phenotype of 20,000 knockout mouse strains. [1] [2] [3] Launched in September 2011, [1] the consortium consists of over 15 research institutes across four continents with funding provided by the NIH, European national governments and the partner institutions.
Additionally, gene knockouts are not always a good model for human disease as the mouse genome is not identical to the human genome, and mouse physiology is different from human physiology. The KO technique is essentially the opposite of a gene knock-in. Knocking out two genes simultaneously in an organism is known as a double knockout (DKO).
Each stem cell contains one mutant gene copy and one 'wild-type' (normal) gene copy. The entire library is intended to mutate 13,000 genes in total. Of these 13000 mutant genes, 8000 mutations in mouse ES Cells are 'targeted': that is, the mutation which knocks out gene function is inserted precisely into the genome.
Mouse Genome Informatics (MGI) is a free, online database and bioinformatics resource hosted by The Jackson Laboratory, with funding by the National Human Genome Research Institute (NHGRI), the National Cancer Institute (NCI), and the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

The Mouse Phenome Database (MPD) is a web-accessible database of strain characterization data for the laboratory mouse, to facilitate translational research for human health and disease. MPD characterizes phenotype as well as genotype , and provides tools for online analysis.
