The mouse is a key model organism for the understanding of mammalian biology because it has been well studied and is genetically and physiologically similar to humans. To utilize mouse data to its fullest, we have developed an integrated database of mouse genetic, genomic and biological data. The Mouse Genome Informatics Database (MGI) is used by the international scientific community as its primary resource for mouse information and as a tool for new biological discovery. The database contains a wide variety of data pertaining to genes, their DNA and protein sequences, and the phenotypes that result from mutations in different genes. The three central components of MGI are the Mouse Genome Database (MGD), an internationally recognized database for the laboratory mouse, the Mouse Tumor Biology (MTB) database, which facilitates the selection of experimental models for cancer research, and the International Mouse Strain Resource (IMSR), a searchable online database cataloging mouse stocks available worldwide. The database continues to expand to keep abreast of new technologies and to grow with our expanding knowledge of how the genetic blueprint of DNA manifests in traits of a living individual.
The Mouse Genome Database (MGD, http://www.informatics.jax.org) serves the international biomedical research community as the central resource for integrated genomic, genetic and biological data on the laboratory mouse. To facilitate use of mouse as a model in translational studies, MGD maintains a core of high-quality curated data and integrates experimentally and computationally generated data sets. MGD maintains a unified catalog of genes and genome features, including functional RNAs, QTL and phenotypic loci. MGD curates and provides functional and phenotype annotations for mouse genes using the Gene Ontology and Mammalian Phenotype Ontology. MGD integrates phenotype data and associates mouse genotypes to human diseases, providing critical mouse-human relationships and access to repositories holding mouse models. MGD is the authoritative source of nomenclature for genes, genome features, alleles and strains following guidelines of the International Committee on Standardized Genetic Nomenclature for Mice. A new addition to MGD, the Human-Mouse: Disease Connection, allows users to explore gene-phenotype-disease relationships between human and mouse. MGD has also updated search paradigms for phenotypic allele attributes, incorporated incidental mutation data, added a module for display and exploration of genes and microRNA interactions and adopted the JBrowse genome browser. MGD resources are freely available to the scientific community.
