The International Mouse Phenotyping Consortium (IMPC) portal provides a freely available comprehensive catalogue of mammalian gene function, using the mouse as a model. By applying a standardised phenotyping pipeline to single-gene knockout mouse lines, the IMPC identifies the physiological systems that are disrupted when a gene is disabled and thus establish gene-phenotype associations. This course will show you how to navigate the IMPC portal to find phenotypes, disease models and knockout mouse strains for a gene of interest.
