There are several thousand different strains of knockout mice. [3] Many mouse models are named after the gene that has been inactivated. For example, the p53 knockout mouse is named after the p53 gene which codes for a protein that normally suppresses the growth of tumours by arresting cell division and/or inducing apoptosis.

A conditional gene knockout allows gene deletion in a tissue in a tissue specific manner. This is required in place of a gene knockout if the null mutation would lead to embryonic death, [13] or a specific tissue or cell type is of specific interest. This is done by introducing short sequences called loxP sites around the gene.
The consortium encompasses four major, high-throughput gene-targeted mutagenesis programs: the National Institutes of Health (NIH)-sponsored Knockout Mouse Program (KOMP) and state-funded Texas Institute for Genomic Medicine (TIGM) in the U.S., the North American Conditional Mouse Mutagenesis (NorCOMM) Program in Canada, and the European ...

Gene knock-in originated as a slight modification of the original knockout technique developed by Martin Evans, Oliver Smithies, and Mario Capecchi.Traditionally, knock-in techniques have relied on homologous recombination to drive targeted gene replacement, although other methods using a transposon-mediated system to insert the target gene have been developed.

[23] [24] However it took another eight years before transgenic mice were developed that passed the transgene to their offspring. [25] [26] Genetically modified mice were created in 1984 that carried cloned oncogenes, predisposing them to developing cancer. [27] Mice with genes knocked out (knockout mouse) were created in 1989.
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.
