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. See General Guidelines for MGI Query Form Searches for answers to questions about submitting queries, using operators, choosing sort orders, speeding up queries, and similar help topics.

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 | Map position | Gene Ontology classifications | Protein domains | Mouse phenotypes & mouse models of human disease | Sorting & output format

Gene/Marker Symbol, name, or synonym for a genetic marker.
  • Enter one or more symbols/names/synonyms (separated by commas). Note: If the term itself contains a comma, put the entire term in quotation marks to ensure that the search is on the exact phrase (example: "cyclin B1, related sequence").
  • By default, the search is on current and old symbols/names, synonyms, alleles, and homologs. However, you can limit the search to current symbols or names.
  • The operators (begins, = , contains) present additional search options. The default is contains.
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.
  • An empty box indicates no choices in an entire category/subcategory.
See Genome Feature Type Definitions for a table describing all choices.
Map position 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.
  • You cannot combine genome coordinates and cM position with one another.
  • For Marker Range, you can enter any marker(s) — except QTL(s) — with coordinates.
  • When using chromosome(s), you can also define genome coordinates or cM position.
  • You cannot combine genome coordinates and cM position with one another.
  • For Marker Range, you can enter any marker(s) — except QTL(s) — with coordinates.
  • 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.
    Gene
    Ontology
    classification
    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.

    See Phenotype/Disease.
    Note: The query returns a marker only if at least one associated allele satisfies whatever you enter in this section.
    Sorting and
    output format
    Sort by Click one of the choices (Nomenclature or Genome Coordinates) to determine the order of any results on the summary page.
    The combination of sort option and search parameter affects the order and type of results listed on this summary page.
    • If you search using current & old symbols/names, synonyms, alleles, homologs, the summary page columns are Genetic Location, Genome Coordinates, Feature Type, Symbol/Name and Matching Text.
    • If you search on current symbols/names, the summary page column headings are Genetic Location, Genome Coordinates, Feature Type and Symbol/Name.
    Maximum ReturnedThe default is 500. You can increase this by clicking no limit.
    Output Choose from the list depending on how you wish to view the report.

    What happens if I click the Your Input Welcome button on the detail page?

    The Your Input Welcome button appears at the top right of your screen as part of the detailed query results. Clicking the button brings up a dialogue box to use for submitting updates and corrections to the data you are viewing. Our User Support staff will review your comments and make sure the appropriate changes are made. This provides an easy way for you to help us keep data current.

    How do I retrieve my results as a text file?

    At the bottom of the form, in the Sorting and output format section, change the Output from Web (the default) to Tab-delimited.

    Are there any sample queries?

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

    1. How do I find genes with symbols/names containing cd2 mapped to Chr. 3 between 30 and 50 cM?
      Gene/Marker Symbol/Name:    cd2
      Chromosome(s):   3
      cM Position:    between 30.0-50.0
      The search yields a list of at least 3 markers containing the alphanumeric cd2 on Chromosome 3.
    2. Which histocompatibility markers are located on Chromosome 4?
      Gene/Marker Symbol/Name: CONTAINS 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: BEGINS 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).
