For Mus musculus Build GRCm39 patch information and statistics, see The Genome Reference Consortium web site. MGI now incorporates strain genome data of de novo sequenced mouse strains from the Wellcome Sanger Institute's Mouse Genomes Project (MGP) and the European Bioinformatics Institute (EBI). Genome feature annotations are provided by the GENCODE consortium, the University of California Santa Cruz (UCSC) Genome Browser Group and the Mouse Genomes Project. Browse strain genome features using the Multiple Genome Viewer (MGV).

Genes, Genome Features

MGI contains information about mouse genes, DNA segments, cytogenetic markers and QTLs. Each record may include the marker symbol, name, other names or symbols and synonyms, nomenclature history, alleles, STSs, chromosomal assignment, centimorgan location, cytogenetic band, EC number (for enzymes), phenotypic classifications, human disease data, Gene Ontology (GO) terms, MGI accession IDs and supporting references. See Interpreting a Genes and Markers Summary and Interpreting Gene Details for more information about the content of the display of a marker record as it appears in the query results.


MGI contains a variety of maps and mapping data. Users can create graphical displays of genome features on the mouse genome using the JBrowse Genome Browser. A variety of types of Genetic Mapping Data are available from marker detail pages, including data from genetic linkage crosses, cytogenetic localization, recombinant inbred and recombinant congenic strains, and radiation hybrid mapping.
