How do I use this query form?

To search for detailed data using this query form, enter or select values in one or more of the query form fields described in the following paragraphs. After entering values in the form fields, click Search to submit the query. Click Reset to clear the fields and return any default values.


What values are acceptable in each of the query form fields?

Use these fields to search for genes and markers by name, location, GO terms, protein domains, or for mouse phenotypes and mouse models of human disease.

Gene/Marker | Feature Type | Genome Location | Gene Ontology classifications | Protein domains | Mouse phenotypes & mouse models of human disease
Gene/Marker Gene/Marker Symbol/Name: Use this field to search for a mouse genetic marker or set of markers with a similar nomenclature.
  • The gene nomenclature field supports an asterisk as a wild card. A search for pax* finds gene symbols and names that begin with pax.
  • A search for *box* looks for nomenclature that contains box. This search finds the arginine decarboxylase gene, homeobox genes and paired box genes.
  • A search for *apoe* finds not only the Apoe gene but transgenes containing APOE.
  • A search for growth factor finds nomenclature containing growth AND factor.
  • Synonyms (unofficial gene names used in publications and former official gene symbols) and symbols and names for homologous genes for other vertebrate species are also searched.
  • This field searches only alphanumeric characters. Single and double quotes, commas and hyphens are ignored.
Feature Type Use this field to query for features in a selected category. Numbers in parentheses next to each feature type indicate MGI marker totals per category.
  • Click Show/Hide to expand/contract all list choices or click ► or ▼ open/close a category or subcategory.
  • Click the box next to each item you wish to include in the search. Check marks indicate your choices.
  • Mouse over a feature type to view its definition.
  • Clicking the box beside a major category (any item that opens to subcategories, e.g., all feature types, gene, non-coding RNA gene) selects all items beneath it.
  • A minus in a box beside a category indicates that discrete items beneath it are selected (and not the entire category or subcategory, e.g. miRNA gene and lincRNA gene and not all non-coding RNA genes).
  • Checking all categories has the same effect as checking none of the categories. If you do not click any category, the search includes them all.
See Genome Feature Type Definitions for a table describing all choices.
Genome location Use the map position parameters ( Chromosome(s), Genome Coordinates, Marker Range, and cM Position) to limit the scope of your query.
  • When using chromosome(s), you can also define genome coordinates or cM position.
  • For genome features in the pseudoautosomal region (PAR), to search for all genome features in the PAR, select chromosome XY (pseudoautosomal) without entering genome coordinates. To search for genome features in the PAR by coordinates, select the chromosome (X or Y) to which the input coordinates correspond.
  • You cannot combine genome coordinates and cM position with one another.
  • For Marker Range, you can enter any marker(s) with known coordinates. The query is inclusive of the markers you enter.
If you wish to search with multiple regions, or search with human regions instead of mouse, you can do this with the Human—Mouse: Disease Connection. See Using Map Position Fields on MGI Query Forms for further details about entering values in these fields.
Genes may be described using three broad categories reflecting biological roles: Molecular Function, Biological Process, or Cellular Component. The Gene Ontology (GO) Consortium has developed structured vocabularies to specify detailed aspects within each category. MGI uses GO terms to annotate gene records. See Using Gene Ontology Classification Fields on MGI Query Forms for details.
Protein domains
InterPro Protein Domains InterPro accession ID for a protein family, domain, or functional site.
  • To find an accession ID, click Browse InterPro protein domains.
  • Copy and paste (or type) an ID or description into the box.
  • To enter more than one ID or description, use AND between them. Searching on term1 AND term2 returns markers annotated to both term1 and term2.

human disease

See Phenotype/Disease.
Note: The query returns a marker only if at least one associated allele satisfies whatever you enter in this section.

Are there any sample queries?

The following examples show the field values that produce the given results. Default values for other fields are assumed.

  2. Which histocompatibility markers are located on Chromosome 4?
    Gene/Marker Symbol/Name:  histoc*
    Chromosome(s): 4
    The search yields a list of at least 5 histocompatibility markers on Chromosome 4.
  3. What information does MGI have on the Chrng marker?
    Gene/Marker Symbol/Name: chrng
    This search yields a link to the marker record for Chrng (and any other markers for which the symbol or name begins with the characters chrng).
  4. List all the genes on any chromosome between cM position 10 and 15.
    Chromosome(s): 2
    cM Position Between: 10.0-15.0
