Note
E.g., "Mus" rather than "Mus musculus".
If the subspecies is known then the Patient Species Description (0010,2201) or Patient Species Code Sequence (0010,2202) may describe the subspecies.
Note
E.g., "Canis lupus familiaris" rather than "Canis lupus".
C.7.1.1.1.4 Patient Strain and Genetic Modifications
The strain of an animal (group of animals that is genetically uniform), if known, may be encoded in Strain Description (0010,0212). The nomenclature used may be encoded in Strain Nomenclature (0010,0213). A precoordinated code identifying the strain may be encoded in Strain Code Sequence (0010,0219).
Defined Terms for Strain Nomenclature (0010,0213) and Genetic Modifications Nomenclature (0010,0223):
MGI_2013International Committee on Standardized Genetic Nomenclature for Mice, Rat Genome and Nomenclature Committee. MGI-Guidelines for Nomenclature of Mouse and Rat Strains. 2013/10. Available from: http://www.informatics.jax.org/ mgihome/nomen/strains.shtml
Note
•A pair of text and nomenclature Attributes are used, since standard nomenclatures typically define values that are con- structed from multiple components, and do not distinguish between value and meaning. These are distinct from the preco- ordinated codes used in Strain Code Sequence (0010,0219).
•Some strain and genetic modification nomenclatures make use of superscripts. To encode these superscripts consistently in an unformatted string, the convention of enclosing the superscript text in "<" and ">" pairs may be used. E.g., "D2.B6- Ahrb-1/J" would be encoded as "D2.B6-Ahr<b-1>/J".
•Relevant information that is not encoded in the formal description of the strain (i.e., not defined in the nomenclature used), such as the number of transgenes, may be encoded as plain text in Strain Additional Information (0010,0218).
The strain of an animal may be more specifically identified by the Attributes within Strain Stock Sequence (0010,0216).
Note
•The MGI-Guidelines for Nomenclature of Mouse and Rat Strains recommends the use of the laboratory codes assigned by the Institute of Laboratory Animal Research (ILAR). See the International Laboratory Code Registry (ILCR) http:// dels.nas.edu/global/ilar/lab-codes.
•Because allele names are closely tied to gene names/symbols it is necessary to have a unique and permanent code for any allele that is part of a genotype of interest. For mice, MGI is the authoritative source of the nomenclature for genes and alleles and maintains unique, permanent codes for these entities. The MGI provides a report of all precoordinated MGIcodesthatareassignedtospecificstrainsathttp://www.informatics.jax.org/downloads/reports/MGI_Strain.rpt.These may be used in Strain Code Sequence (0010,0219) and Genetic Modifications Code Sequence (0010,0229) with a coding scheme of "MGI".
•Another source of pre-coordinated codes for strains is the NCI Thesaurus, which includes a snapshot of strains from the International Mouse Strain Resource (IMSR), as children of (C14421, NCIt, "Inbred Mouse Strains"). See http:// ncit.nci.nih.gov/ncitbrowser/pages/concept_details.jsf?dictionary=NCI_Thesaurus&code=C14421.
•For example, a C57BL/6J mouse strain from The Jackson Laboratory might be identified as:
Strain Description (0010,0212) = "C57BL/6J"
Strain Nomenclature (0010,0213) = "MGI_2013"
Strain Code Sequence (0010,0219)
