This help document describes Phenotypic Allele Details.
The title on an allele detail page takes the following form:
[allele type] Detail
[allele type] is the category
used to narrow the allele search. The category can be spontaneous, induced (chemically, radiation, or transposon), transgenic (random, expressed; random, gene disruption; Cre/Flp; transposase), gene trapped, targeted (floxed/frt, reporter, knock-out, knock-in) or QTL.

Your Input Welcome
The Your Input Welcome button appears (top right) as part of the detailed query results for an allele. Click the button to bring up a form for submitting updates and additions to the allele data on view. This provides an easy way to help keep data current.
If the MGI database contains multiple phenotypic images for the mouse, a representative image appears on the Phenotypic Allele Detail page (top right). Click anywhere on the image to see the Image Detail page for the representative image or click Show the # image(s) involving this allele to view them all.
The Mutation description section may also contain images that define the mutation. Click on an image for a larger view.
The table below describes the fields in an allele detail report.
- When information for a field is not available or is not pertinent to a given allele, it does not appear.
- Field names vary depending on the type of allele.
- a Transgene Detail report has field names titled Transgene origin and Transgene description as well as transgene name and location information in the Nomenclature section.
- a QTL detail report has field names entitled Variant origin and Variant description. The Nomenclature section may contain information about the QTL name, location, and genetic position, and/or a QTL note.
|Symbol||The symbol of the allele.
The allele symbol is composed of the gene symbol and the allele designation. If the gene is unknown, only the allele designation appears.

|Note||Any clarifying details from MGI curators.|
|Inheritance||Phenotypic effect of the allele when heterozygous with the wild type allele. Note: This information is primarily entered for spontaneous and chemically or radiation-induced alleles and QTLs.|
|Sequence tag||Click ► to open the display.
Click ▼ to close the display.
|Tag ID||Cell line sequence tag identifier, assigned by the creator. The link goes to the external resource for this sequence (for example, IGTC, dbGSS). |
|GenBank ID||The dbGSS identifier assigned to this sequence tag.|
|Tag Location (strand)||Chromosome location, genome coordinates in base pairs, and the indicator of how the strand is oriented to the genome (+ or -), based on the current NCBI build.|

The image that appears is a genome browser view of the mutation and contains a link to the MGI Mouse Genome Browser and all the genome sequence tags in the region. When numerous gene traps appear, use the Scroll/Zoom feature (yellow arrows, middle of the page) to locate a given trap.
|Activity||Recombinase activity was assayed for this allele in all (the high-level terms for the) anatomical systems listed.
Recombinase activity is displayed in a table of Systems/Structures and ages assayed. The Activity in Systems/Structures column lists anatomical Systems/Structures assayed for recombinase activity.
The age ranges are as follows:
- If a structure you are interested in does not appear, it means that currently there are no assay data for this allele in that structure.
- The sort order is alphabetical (e.g., behavioral/neurological before cardiovascular, skeleton before skin/coat/nails).
- To expand or collapse all structures, click show
or hide (at the top of the Activity in Systems/Structures column).
- To expand or collapse a single system, click the ► or ▼ beside it.
- A check mark (✓) means recombinase activity was assayed and detected in the system/structure and age. A minus sign (-) means recombinase activity was assayed and not detected in the system/structure and age.

|User Notes||If researchers have submitted additional information to MGI regarding the tissue activity of this allele, this section will be present. Toggle the ► to view the information.|
Each listed system links to a Recombinase Activity Detail page associating expression assays of type Recombinase reporter, In situ reporter (knock in) and In situ reporter (transgene) with genotypes.
If you have information about this allele that is not displayed on this Allele Detail page, such as ectopic activity observed for the allele or constitutive activity for an inducible allele, click the Your Observations Welcome button to have this information included in MGI.
|Phenotypes||See Interpreting the Phenotype summary table.|
|Disease models||List of all diseases modeled, or attempted to be modeled with this allele. These annotations may be of the following types:
- phenotypic similarity to human disease.
- transgenes or other mutation types (appears only if there are diseases annotated to an allele of a non-gene marker).
- no similarity to the expected human disease phenotype (that is, one or more human genes may be associated with the human disease; the mouse genotype may involve mutations in orthologous genes; but the phenotype does not resemble the human disease). These are noted by the ∅ symbol.
|Human Disease||All human diseases annotated to any mouse genotype containing the allele. Full disease term (e.g., Aniridia; Peters Anomaly; Frasier Syndrome; rheumatoid arthritis), linked to the (MGI) Human Disease Ontology (DO) Browser record. The IDs links to a popup of IDs associated with the disease, linked to the appropriate source, when possible. Examples are DO IDs, OMIM IDs, and ICD-9 codes.|
|Colored boxes, |
- A Key decodes the information.
- Each column heading contains a color, an abbreviation, and a number.
- Colors correspond to genotypic "states."
- Abbreviations are "shorthand" for those states (e.g., hm stands for homozygous).
- Numbers are sequential; there is one for each genotype.
- The colors make it easy to distinguish genotypes from one another, especially when the summary extends horizontally.
|Expression||A link to expression data in mice carrying this allele.
|Find Mice (IMSR)||Information about the availability of mouse strains and/or cell lines of this allele in the International Mouse Strain Resource (IMSR). There is also an indicator of whether or not there are any strains or lines available for any mutation of this gene. The International Mouse Strain Resource (IMSR) is a searchable online database of mouse strains, stocks, and mutant ES cell lines available worldwide. The IMSR does not house any stocks but if you follow these links to the IMSR it will search for stocks from several providers. In your IMSR search results, the Strain Name links to the repository's site, the Repository links to an e-mail form so you can ask about or order the stock and the Allele Symbol links to the MGI Allele Detail page. The IMSR search may also find stocks with incidental mutations in this and many other genes.
