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.

Human–Mouse: Disease Connection (HMDC). The top panel shows the upper portion of the HMDC homepage. Searches can be initiated using human or mouse gene(s), location(s) or disease/phenotype terms. Alternatively VCF files or files of gene symbols or IDs can be submitted as search parameters. The disease/phenotype search box has an autocomplete feature allowing the user to choose the exact term desired. In this example Angelman Syndrome was selected. The results (middle panel) are presented in grid format, listing genes associated with Angelman Syndrome in human or mouse in the left-most columns. Grid colors representing mouse data are blue and human data are orange, with color intensity being darker for more annotations. Phenotype and disease terms are indicated in the columns on the right-hand side of the grid. Note that both human and mouse homologs (
UBE3A and Ube3a, respectively) are associated with the disease. In addition, human CDKL5 and MECP2 are associated human genes and Snrpn is an associated mouse gene. This might suggest additional mouse models could be created by mutating mouse genes Cdkl5 or Mecp2; and that other potential human mutations in SNRPN might be examined as an Angelman Syndrome candidate gene. For genes that have known models in mice ( Snrpn and Ube3a) a phenotype profile is provided. The red asterisk (*) indicate tabs that display data in a tabular format by genes or by diseases. Each colored cell within the grid is interactive and clicking on a cell leads to further details (bottom panel).
Mouse genome annotation browser implemented in JBrowse. Example of the allele and phenotype annotations for mouse
Cav2 and Cav1 genes. The MGI track displays unified mouse gene catalog contents. Tracks from external genome annotation groups such as NCBI provide details regarding transcriptional isoforms of mouse genes. Track controls allow users to customize aspects of the display and to download data from the JBrowse tracks.
Genome feature–genome feature cluster relationship. Top panel shows the upper portion of the homeobox A cluster detail page. Cluster members are now indicated, with a link to the full list of genes in the cluster membership. Each cluster member gene page (bottom panel) shows what cluster that gene is a member of, with a link to the cluster's detail page.
Interaction Explorer. On the
Bmp4 gene detail page (top panel), a new ‘Interactions’ ribbon has been added. The initial sets of interaction data incorporated by MGD are interactions of genes with microRNAs. The Bmp4 gene interacts with 50 genome features that can be viewed by selecting the ‘View All’ button. The Interaction Explorer page (bottom panel) graphically and dynamically displays interactions on the left and provides a tabular view on the right. By using the filtering and sorting options, users can limit the number of interactions shown. The graphical view changes in response to such filtering and can be made larger or smaller to aid viewing. The selected marker (here, Bmp4) is shown in the center of the graph display with blue lines connecting validated interactions and red lines connecting predicted interactions.
Gene–allele relationships. MGD now represents the components of complex mutations. For a given complex mutation (here,
bpck), the individual genes or genome features mutated are viewable, along with the type of change that each has undergone (top and middle panels). Conversely, any gene detail page for a single genome feature component of a complex mutation (here, Cdh17 is a component of the complex mutation bpck) indicates the existence of its participation in ‘genomic mutations’ that include that particular gene.
Incidental Mutations from ENU experiments. Incidental mutations are accessed from the Gene Detail Page or Allele Detail Page. The top panel shows the
Spag9 gene page with a link to two incidental mutations in this gene from the Mutagenetix mutation collection. Spag9 mutations were discovered in two mutant stocks from this collection. The bottom panel shows the Spag9 allele detail page. Six incidental mutations were detected in the stock carrying this mutation. m1Btlr
Allele attributes and project collections. Screen shot of the Categories ribbon from the Phenotypes, Alleles & Disease Models Query Form (
http://www.informatics.jax.org/allele/). When searching for alleles with specific characteristics a generation method may be selected, one or more allele attributes may be selected, and membership of an allele in a project collection may be selected. For example, one might select the generation method ‘Chemically induced (ENU)’ and attribute ‘Hypomorph’ to find those ENU mutations that show partial function. A selection from the project collections attribute would further restrict one's query to those alleles generated in the project(s) selected.
