Symbol: This is the official symbol assigned to this strain according to the
strain nomenclature guidelines. This is a combination of strain and
substrain designations for inbred strains (or symbol and ILAR code for
other strain types).
Strain: The official strain symbol.
Substrain: The official substrain symbol - this can be a collection of ILAR lab
codes defining the history of this particular strain. Can also be
found in pulldown section below with links to the strain report pages.
Full Name: If the strain has a text name then it is displayed here; this is not visible if no name is associated to the strain, as in this example.
Ontology ID: The identification number of the strain ontology term assigned by RGD, linked to the term in the ontology browser. In the strain ontology, rat strains are organized in a hierarchical fashion based on the type of strain and the way they were developed.
Also known as: Old symbols and synonyms that were used for the
strain. If a strain is renamed to comply to the guidelines of strain
nomenclature, then the symbol used by researchers is mentioned here.
Type: One word description of the category of the strain - inbred, congenic, consomic, outbred.
Source: The name of the lab, department, university or company from where this particular strain can be obtained.
Origin: A brief description of the mothod used to generate this strain.
See Also: Links to other substrains of this strain, or the main strain for this substrain.
These pages often have extra information about a particular strain, especially
the parental strain page (e.g. BN would be the parental strain for the BN/Ssn
substrain). Not present in this example.
Genetic Markers: Genotype for standard genetic markers used in the characterization of inbred
strains.Not present in this example.
Coat Color: The coat color of this strain - e.g. Albino, brown, white.
Inbred Generations: The number of generations that this strain has been inbred at the time the
data was curated.
Model: If the strain is a model fo rany specific disease as mentioned by the authors of a paper then this informations is displayed here. Not present in this example.

This section at the top right side of the page has more information about strains.
RGD Object Information
The RGD ID for the strain, the date the record was created in the
database, the species, the date the strain information was last updated,
and the status of the record in the database appear in this box.
This section has subsections containing ontology annotations assigned to the strain. These are organised by ontology type, which includes the Mammalian Phenotype ontology and disease vocabulary. Additional subsections contain information about phenotype analysis in the PhenoMiner tool, annotations to the strain in disease portals and a list of curated references for the strain. By default the subsections are closed to facilitate navigation through the page but each can be expanded with a single click anywhere on the title bar.
These annotations represent disease to strain associations manually curated from the biomedical literature. The terms come from a disease vocabulary which merged OMIM and MeSH disease vocabularies. The combined vocabulary was created at the Comparative Genomics Database (CTD), disease annotations are followed by the evidence codes IAGP or IED and the reference from where this annotation was derived.
These annotations represent the association of strains with particular mammalian phenotypes. The terms come from the Mammalian Phenotype Ontology developed at MGI (http://www.informatics.jax.org/, Genome Biol. 6(1):R7. Epub 2004 Dec 15.) The terms are supported by the same group of evidence codes as used for disease vocabulary annotations.
Phenotype Values via Phenominer
This is a list of all the Phenotypes that are measured using this strain. These are retrieved from the RGD PhenoMiner tool, which houses phenotype data. A click on 'View chart' goes to the PhenoMiner tool displaying the details of the phenotypes. 'Download data table' opens a downloadable version of this data as an Excel spreadsheet and 'View expanded data table' gives an enhanced version of this data.
RGD Disease Portals
Strain report pages are linked to disease portals in which this strain is annotated. If a strain is a model for a particular disease then it is mentioned in the portal's 'Rat Strain Models' tab.
References - curated
A list of all references that have been used by the RGD curation team
for annotating this strain. These link out to the RGD Reference report
pages which have the abstracts of the articles. There is a link to
PubMed from this page.
Strain QTL Data
This is a list of QTLs that have been identified using this strain, and are annotated to it. The QTLs are linked to the RGD QTL report pages.
This section is visible only in the congenic strains that have SSLPs/genes/ESTs used as markers to define the introgressed segment.
RGD Curation Notes (Strain
These are free text notes that give us the information that is not captured by the disease and phenotype annotations, These are curated under the following headings:
Anatomy, Behavior, Characteristics, Drugs and Chemicals, Infection, Immunology, Life Disease, Physiology and Biochemistry, Reproduction and other.
This indicates when the strain was named and lists dates of any symbol changes.
Strain Curation Process in RGD
RGD curates all the strains (inbred, congenic, consomics, etc.) that are mentioned in all rat QTL papers. Besides this the strains submitted to RGD from researchers and vendors are curated. RGD has weekly searches set up in PubMed based on the different strain types and names of authors who work on specific strains. These searches bring lists of papers which are curated by RGD.
