This initiative is funded through the NIH Common Fund, which supports cross-cutting programs that are expected to have exceptionally high impact. All Common Fund initiatives invite investigators to develop bold, innovative, and often risky approaches to address problems that may seem intractable or to seize new opportunities that offer the potential for rapid progress. The purpose of the Knockout Mouse Phenotyping Project (KOMP2) is to produce a comprehensive resource of null-mutant mice, and associated phenotype data, for the purpose of elucidating functional information for each protein-coding gene in the mammalian genome. The goal of this FOA is to provide informatics support to NIH funded projects that are performing high-throughput broad based phenotyping of mouse knock-out (KO) lines (see RFA-RM-15-017) and to coordinate with international efforts so as to integrate all data into a common database under the auspices of the International Mouse Phenotyping Consortium (IMPC). The Data Coordination Center and Database (DCCDB) will perform the curation, analysis, visualization, and dissemination of the phenotype data from the knockout lines. Curation will require integration with other data sources. Analysis will require further development and validation of statistical methods.Visualization and queries will require innovative tools to disseminate the data in a real-time environment. The ultimate goals of these efforts are to enhance the ability of the biomedical research community to identify new disease models, to better understand phenotypic patterns, and to gain a more comprehensive understanding of the underlying function of each gene.
