This help document answers the following questions:
Use this query form to find phenotype and disease associations for human and mouse genes and genome regions. You can enter a combination of multiple phenotype terms, disease terms, gene symbols, accession identifiers (IDs) and genome coordinates.
|phenotype||A description of the observable state of an individual with respect to some inherited characteristic. See also dominant and recessive in the MGI Glossary.|
|disease||A human disease, syndrome, or condition listed in the the Disease Ontology (DO) or OMIM (Online Mendelian Inheritance in Man) database.|
|allele||One of the variant forms of a gene, differing from other forms in its nucleotide sequence. Allele category, allele combination and allele pair also appear in the MGI Glossary.|
|allele name||In MGI, an allele name is a word or phrase that uniquely identifies an allele of a given gene. The allele name has an abbreviation that is the allele symbol added as a superscript to the gene symbol. See also Gene Name in the MGI Glossary.|
|allele symbol||In MGI, an allele symbol is a unique abbreviation for the allele name of a given gene. Allele symbols take the form of superscripts added to the gene symbol. See also Gene Name and Gene Symbol in the MGI Glossary.|
|See Allele Combination in the MGI Glossary.|
Note: Some terms may have unique definitions in the context of MGI queries and results. For more information, see:

|Search by: Gene Symbol(s) or ID(s) | Gene Name | Phenotype or Disease Name | Phenotype or Disease ID(s) | Genome Location | Gene File Upload|
|Gene Symbol(s) or ID(s)||Symbol, synonym, vertebrate homolog or ID for a human or mouse genetic marker.
|Gene Name||Name or synonym for human or mouse genetic marker. If you enter more than one word, this field automatically ANDs them. A search for paired box finds genes with names that contain both paired AND box.|
|Phenotype or Disease Name||The Search by Disease or Phenotype Name field is a full-text search field.
|Phenotype or Disease ID(s)||IDs from the Mammalian Phenotype (MP) Ontology, Human Phenotype Ontology (HPO), Disease Ontology (DO) or Online Mendelian Inheritance in Man (OMIM). Be aware that the MP and HPO IDs use the prefixes: MP: and HP:, OMIM uses OMIM:, and the DO uses DOID:.|
|Genome Location||You can enter a mouse or human genomic region (e.g. 2:105668896-108698410 or chr13:22210730-22311689) and use the radio button to specify the species (Mouse or Human). Use MT for the mouse mitochondrial chromosome.
|Gene File Upload||Upload a column of gene symbols and/or their IDs. To do so, follow these steps:
Yes. The mammalian phenotype terms are from the Mammalian Phenotype (MP) Ontology, a community effort to provide standard terms for annotating phenotypic data. The Mammalian Phenotype Ontology has a hierarchical structure that permits a range of detail from high-level, broadly descriptive terms to very low-level, highly specific terms. This range is useful for annotating phenotypic data to the level of detail known and for searching for this information using either broad or specific terms as search criteria. You can either browse or search the Ontology with the Mammalian Phenotype Browser. You can use this browser to view terms, definitions, and term relationships in a hierarchical display. Links to summary annotated phenotype data at MGI are provided in Term Detail reports. See Using the Mammalian Phenotype (MP) Browser for additional help.
The HMDC also searches the Human Phenotype Ontology (HPO). The HPO provides a standardized vocabulary of phenotypic abnormalities encountered in human disease. You can search the HPO vocabulary directly with the Human Phenotype (HPO) Browser.
Yes. The Disease Ontology (DO) contains human disease, syndrome, and condition terms. You can browse the vocabulary and find links to associated genes and mouse model information by using the Disease Ontology Browser. Navigate the vocabulary until you find the term you are looking for. See Using the Disease Ontology (DO) Browser for additional help.
MGI uses the doid-merged.obo version of the DO ontology. This version includes asserted is_a relationships, is_a relationships derived from tissue/organ location information and additional OMIM cross-references from susceptibility relationships.
Yes, you can use the Phenotype or Disease Name or the Phenotype or Disease ID(s) fields to search for phenotypes and/or diseases. Choose the appropriate Boolean term, AND or OR, for your search.
Yes, you can.
When you search by HPO or MP term ID, results returned are only for human or mouse annotations, respectively. To expand your result set, you can add related terms from the other ontology by clicking on the Click to hide search button. See the next section: How do I expand an ID search to include both mouse and human data?
A table of related terms appears in the window with the following columns:
|Search Term (ID)||The terms and IDs you searched with.|
|Search Term Definition||The definition of that term|
|Match Method||Method used to match your search term. Can be manual (i.e. via a curator) or lexical (i.e. a computationally matched word)|
|Match Type||How the two terms are related. Definitions are found at the W3C website|
|Matched Term||Term that matches the searched term|
|Match Term Synonym||Alternate names for the matched term|
|Match Term Definition||The definition for the matched term|
|Add to Search||Check the related terms you wish to add to your search and click the "Add IDs to HMCDC search."|
This section is currently under development. One issue is that trailing commas in the term matching tool invoke the "no match found" message. This will be fixed in the next release.

Your search results are displayed within three tabs: Gene Homologs x Phenotypes/Diseases, Genes and Diseases. The Gene Homologs x Phenotypes/Diseases grid only displays genes with phenotype and disease associations. With all searches, the Gene Homologs x Phenotypes/Diseases tab is the default selection.
The Gene Homologs x Phenotypes/Diseases tab, the default selection, provides an overview of your results in a grid format. The query summary contains the following fields:
Human Gene Symbol of the gene, linked to the Alliance of Genome Resources human gene page. Mouse Gene Symbol of the gene, linked to its MGI gene detail record. Phenotypes And Diseases Starting from the left are high level terms from the Mammalian Phenotype (MP) Ontology for which there are either annotated alleles of the mouse gene or human genes associated with with similar phenotypes through the Human Phenotype Ontology (HPO). See also the Mammalian Phenotype Browser and the Human Phenotype (HPO) Browser. Phenotypes that are only annotated to complex mouse genotypes—those involving more than one genome feature—are not listed in this summary. Phenotypes to all the genotypes associated with an allele can be viewed by following allele symbol links to Allele Detail pages. Listed to the right, after a vertical grey bar, are high-level human Disease Ontology terms associated with the human gene or through mouse models described in publications. The Gene Homologs x Phenotypes/Diseases grid only displays genes with phenotype and disease associations. To see all the genes associated with your search, click on the Genes tab.
Human and mouse phenotype annotations are returned and are indicated by the colors, blue for mouse data and tan for human data.
Some of the human disease terms have been shortened but if you hover your cursor over the term, a pop-up will display the full term name. Highlighted column titles indicate which columns contain phenotype or disease terms that match one or more terms in the search. Highlighting is only displayed on column titles, and only when a phenotype or disease term is used in the search. A column is highlighted when at least one of the genes has an annotation matching your search. So if you search for a general term such as fibrosis, the cardiovascular system column may be highlighted because one gene is associated with cardiac fibrosis. Another gene may not have cardiac fibrosis but is returned because it is associated with pulmonary fibrosis, causing the respiratory system column to be highlighted. Columns that are not highlighted contain additional phenotypes and/or disease terms associated with the mouse model or human gene that is connected to the searched term(s).
The colors, blue for mouse data and tan for human data, get progressively darker with more supporting annotations. The lightest color represents one annotation. 2-5 annotations is represented by a darker shade, 6-99 annotations darker still and more than 100 annotations by the darkest color.
You can hover your cursor over a colored square to see that row's markers and column heading in a pop-up.
The grid contains its own scroll bars, though you may have to move your cursor to the bottom or right edges to make them appear.
Click on a blue colored square for information on mouse genotypes and lower level phenotype terms. The mouse genotypes link to even more detailed phenotype information. Click on a tan colored square for information on the human disease and human phenotypes associated with the human gene.
A bold N in a phenotype column indicates that no abnormal phenotypes of that type were observed in any allele of the gene.
You can filter the grid to show only specified columns and rows by clicking on the Filter by Genes or Filter by Phenotypes button and checking the appropriate criteria and clicking the Apply Filters button.
If you select the Genes tab, the query summary contains the following fields:
Organism States whether the corresponding marker is human or mouse Gene Symbol Symbol of the gene. Mouse genes are linked to their MGI gene detail records. Human genes are linked to their gene pages at the Alliance of Genome Resources. Genetic Location The chromosome and genetic map position for the marker are shown if known. Genome Coordinates The marker's chromosome basepair coordinates, strand and genome build are shown if known. Associated Human Diseases Lists any human diseases described in the Human Disease Ontology (DO) that are associated with the marker. Disease associations for human markers are from the Alliance of Genome Resources Homo sapiens associations disease file and include annotations from OMIM, RGD, NCBI curation, Gene Reviews, and Gene Tests. Mouse markers are associated with human diseases through genotypes described in publications. Mouse markers are associated with human diseases through genotypes described in publications. Abnormal Mouse Phenotypes Reported in these Systems High level terms from the Mammalian Phenotype (MP) Ontology annotated to alleles of the mouse gene. See also the Mammalian Phenotype Browser. Phenotypes that are only annotated to complex genotypes—those involving more than one genome feature—are not listed in this summary but can be found in the Phenotypic Allele Detail Report. References For mouse markers, a link to all the references for the marker is provided. A separate link may be present that links to the just the disease relevant references. The reference summary provides the abstract and links to MGI curated data and when possible, links to PubMed and Journals. Mice With Mutations In this Gene (IMSR) Shows the number of stocks in the International Mouse Strain Resource (IMSR) that contain an allele of the gene. The number links to the IMSR which provides access to stock repositories.
The default sort for this tab is by Marker Symbol, though you can choose to sort by any column by clicking the column headings or the up/down arrowheads ( ▼ ▲).
If you select the Diseases tab, the query summary contains the following fields:
Disease The OMIM disease term linked to the MGI Human Disease and Mouse Model Detail page DO ID The Disease Ontology (DO) accession ID OMIM ID The Online Mendelian Inheritance In Man (OMIM) accession ID Mouse Models The number of mouse models for this disease, linked to Mouse Model details. Associated Genes from Mouse Models The mouse markers used to create the various models of this disease Associated Human Genes Human genes associated with the disease. Disease associations for human markers are from the Alliance of Genome Resources Homo sapiens associations disease file and include annotations from OMIM, RGD, NCBI curation, Gene Reviews, and Gene Tests. References using Mouse Models The number of references describing mouse models of the disease, linked to reference details and curated data
Phenotypes and diseases for mouse genes are limited to those where mutations in only a single gene or introduction of a single transgene are believed to be causing the phenotype. Phenotypes and diseases resulting from multiple mutations or transgenes are excluded. For details, see: Bello SM, Eppig JT, and the MGI Software Group. 2016. Inferring Gene-to-Phenotype and Gene-to-Disease Relationships at Mouse Genome Informatics: Challenges and Solutions. J Biomed Semantics 2016. 7:14. Human diseases are limited to those in OMIM. Human phenotype annotations are limited to those in the HPO-to-OMIM annotation set. Phenotypes and diseases without gene associations may be searched but will not be displayed on the Gene Homologs x Phenotypes/Diseases tab.
You can filter any of the tabbed result views. In your results, click the Filter by Feature Type, Filter by Genes and Filter by Phenotypes/Disease(s) and check the desired criteria by clicking on them. For long lists of results, you can use the Search field within the Filter. This will launch an autocomplete on the second character. When you have finished making your selections, Click the Apply Filters button. This will reduce your results to only those containing the checked items. The filters are applied across all data tabs and to any file you export. Your filter options are limited to those displayed in the Gene Homologs x Phenotypes/Diseases tab. Use the Remove Filters button to remove all filters and return to your original results.
Yes. The Genes and Diseases tabs but not the Gene Homologs x Phenotypes/Diseases tab, provide a tab-delimited text export option. In your search results, click on the Text File icon. Your web browser will download a file of the results.
MGI curators add new annotations from the literature every day. The MGI web site is updated with these and other new data once a week.
