In-Depth Phenotyping and Research Using IMPC-Generated Knockout Mouse Strains Exhibiting Embryonic or Perinatal Lethality or Subviability (R01 Clinical Trial Not Allowed)

The purpose of this Funding Opportunity Announcement (FOA) is to encourage applications to phenotype and/or perform research on embryonic lethal knockout (KO) mouse strains being generated through the International Mouse Phenotyping Consortium (IMPC) of which the NIH Knockout Mouse Phenotyping Program (KOMP2) is a member. The mission of IMPC is to generate a comprehensive catalogue of mammalian gene function that will provide the foundation for functional analyses of human genetic variation. As of November 2019, the IMPC-KOMP2 KO mouse phenotyping effort has generated mutants in 9,051 mouse genes, completed phenotypes of 7153 lines, and released data for 6255 lines corresponding to 5861 mutant genes. Overall, the IMPC hopes to achieve broad-based phenotyping of roughly 20,000 KO strains. About 30% of these strains either are expected to be embryonic or perinatal lethal, or subviable. A large portion of homozygous lethal mutations are expected to have viable heterozygous phenotypes. The scientific community has the unique opportunity to leverage these mouse strains while they are being created and bred as part of the IMPC adult mouse phenotyping effort to perform additional in-depth phenotyping and research.
