Strain State Legend; live. The decision was made not to change the nomenclature of some strains that carry multiple alleles derived from different origins, either because of the way the strain was generated or because the nomenclature would cause additional confusion. Nomenclature In 2001, the International Committee on Standardized Nomenclature for Mice and the Rat Genome and Nomenclature Committee agreed to establish a joint set of rules for strain nomenclature, applicable to strains of both species. Nomenclature for chemically induced and targeted mutations follow the same guidelines as described for mice with spontaneous mutations (see “Nomenclature for Mice with Spontaneous Mutations”). JAX® Mice are named according to the guidelines set by the International Committee on Standardized Genetic Nomenclature for Mice, and strain names are revised as necessary to conform to these guidelines. Laboratory mice are the same species as the house mouse, however, they are often very different in behaviour and physiology.There are hundreds of established inbred, outbred, and transgenic strains. Databases, Internet Resources, and Genetic Nomenclature. To enable broader awareness of nomenclature, The Jackson Laboratory has provided the resources below: Click here to download the Mouse Nomenclature Quick Guide PDF.

Following correct mouse nomenclature, SCID would imply an inbred mouse strain (all letters in capital for the basic strain designation) that at some point during its derivation FORMER NAME: C57BLKS/J-m +/+ Leprdb. Mouse Strains and Genetic Nomenclature Jean-Louis Gu´enet1 and Fernando J. Benavides2 1 D´epartement de Biologie du D´eveloppement, Institut Pasteur, Paris, France The University of Texas M.D. The applications are compiled using a number of information sources (please refer to Mouse Information Resources), but they are not all-inclusive: rapidly advancing biomedical research continually uncovers new applications and uses for spontaneous mutants. Note: This strain was made by mating together, not backcrossing, three individual congenic strains carrying differential alleles already on a C57BL/6J genetic background (B6.C-Igha, B6.PL-Thy1a, and B6.CAST-Gpi1). Strains are listed by their new names, with former names indicated in the JAX® Mice Database. Mouse Nomenclature Standardized Names Mouse genetics Mouse strain Gene-modified Reproducible science This is a preview of subscription content, log in to check access. The ease of rapidly accumulating a large number of mutants requires careful bookkeeping to avoid confusing one mutant with another. Note: This is not a congenic, but rather a mixture of C57BL/6 and 129P2 (from ES cell line) and so is segregating alleles from these two strains. Symbol Definition. Anderson Cancer Center, Science Park-Research Division, Smithville, Texas 2 Most strain names for congenic mice carrying spontaneous and targeted mutations, as well as for a few strains congenic for histocompatibility loci, have not followed standard congenic nomenclature for historical reasons. 2. A strain is considered fully congenic after ten generations of backcrossing (N10). BKS.Cg-Dock7m +/+ Leprdb/J Strain names that contain gene symbols change concordantly with gene symbol changes and also may change as the result of substrain formation from an original colony. Nomenclature for a strain with a spontaneous mutation is as follows: C57BL/6J-Aw–J. Additional information on the origins of transgenes and genetic mutations may be found through the JAX® Mice Database by conducting a search using the gene symbol or stock number of interest. In some cases, multiple lines are derived from the same donor strain and are distinguished by a number and/or letter in parentheses (e.g., B10.129P-H11b(10M)/SnJ and B10.129P-H46b H47b(21M)/Sn). Induced Mutation Knock-out, Knock-in or Floxed Transgenic (Tg) Endonuclease-mediated. The Mouse Genome Informatics (MGI) database is a reliable source of official nomenclature for mouse genes, alleles, and strains; it follows the rules of the International Committee on Standardized Genetic Nomenclature for Mice. We use cookies to personalize our website and to analyze web traffic to improve the user experience. Congenic nomenclature is adopted once a strain has reached the fifth generation of backcrossing (N5), although a strain is not considered fully congenic until N10. Some styles failed to load. A copy of the new guidelines can be viewed at http://www.informatics.jax.org/mgihome/nomen/strains.shtml. Mouse strains exhibit variation in their response to aerosol inhalation of silica (Davis et al. Strain with nomenclature that did not change, but that carries alleles from different origins, Non-Histocompatibility Former gene symbols are listed under symbol common names in the strain detail. A strain, in reference to rodents, is a group in which all members are as nearly as possible genetically identical.In laboratory mice, this is accomplished through inbreeding. Although little has changed as a result … A large number of GEMM strains (Genetically Engineered & Mutant Mice) are congenic strains. Mouse Strain. All offspring are affected mutants (phenotypically manifest the genetic mutation). Note: The Cg (for congenic) is used when there are multiple donor strains or the donor strain is of mixed genetic background. 2001). In response to concerns from the scientific community about the origins of genetic mutations and differences in phenotype due to genetic background effects, the International Committee on Standardized Genetic Nomenclature for Mice and The Jackson Laboratory made a commitment to correct these inconsistencies. The gene and allele symbols for mutant genes are the same until the gene is cloned (see “Nomenclature for cloned mutations,” below). Understanding appropriate nomenclature is essential due to the complexity of strain names for substrains, transgenics, knockouts, etc. The second part of the strain.generation convention describes the number of generations each mouse is from the original founders of that strain. Different alleles of a gene may be represented by a superscript to the gene symbol. Strain Highlights. DNA-isolation protocols for PCR genotyping assays for genetically modified mouse strains. Open Source Software. For example, the recessive yellow (e) and sombre (Eso) alleles of the melanocortin 1 receptor (Mc1r) gene become Mc1re and Mc1rE–so. Examples of these name changes are provided below. For example, the shiverer (shi) mutation in the myelin basic protein (Mbp) gene becomes Mbpshi. In, 2000, a large number of JAX® Mice strain names changed to indicate the mutation’s strain of origin. Mouse/Rat/Chicken. produced using at least 20 consecutive generations of sister x brother or parent x offspring matings Helpful hints for understanding inbred strain nomenclature.

Learn the highlights of mouse strain nomenclature with this poster. The comma between strain abbreviations was replaced with a semicolon to make a clearer distinction from the period in congenic nomenclature. Strain numbers usually consist of 2-3 capital letters designating their source and a serial The Mouse Genome Informatics Database is the authoritative source of official names for mouse genes, alleles, and strains. Each mutant should be assigned a strain number. Guidelines are updated regularly as new nomenclatures are needed and as the International Committee on Standardized Genetic Nomenclature for Mice modifies the nomenclature policies. *Standard strain abbreviations. The rules for naming inbred strains and sub-strains, as finally developed, were submitted to the Commentary: mouse genetic nomenclature. Helpful hints for understanding hybrid strain nomenclature.

The purpose is to increase the pos- sibility of tightly linked genes recombining. Symbols for recessive genes begin with a lower case letter, and symbols for dominant, semi-dominant and co-dominant genes begin with an upper case letter, followed by lower case letters. In this catalog, we list the previous symbol and cross-reference to the new symbol. Learn the highlights of mouse strain nomenclature with our short, interactive tutorial. Gene symbols are italicized. Congenic nomenclature is applied to incipient as well as to full congenics. For example, the myelin deficient (shimld) mutation becomes Mbpshi–mld). Genetic changes which occur in mouse strains are reflected in the formal nomenclature. Laboratory Animals Commentary: Mouse Genetic Nomenclature: Standardization of Strain, Gene, and Protein Symbols J. P. Sundberg1 and P. N. Schofield1,2 Abstract The use of standard nomenclatures for describing the strains, genes, and proteins of species is vital for the interpretation, This chapter presents a basic form of the mouse nomenclature guidelines, covering the nomenclature forms that are most commonly used and encountered.

A 129X1/Sv mouse purchased from Jackson would be called 129.F First Generation Mice (.F1) Note: Additional contributing genetic material may be included in parentheses following the donor strain. The Jackson Laboratory (JAX)® advocates adherence to the mouse strain nomenclature guidelines as described by the International Committee on Standardized Genetic Nomenclature for Mice. Mice with spontaneous mutations are useful for elucidating basic biological processes, studying relationships between gene mutations and disease phenotypes, and modeling human disease. Learn what is in the name of genetically engineered and mutant mouse strains. For example, the shiverer ( shi) mutation in the myelin basic protein ( Mbp) gene becomes Mbp shi. As a result of a communication to Mouse News Letter (1) in which this need was pointed out, a nomenclature committee consisting of T. C. Carter, L. C. Dunn, D. S. Falconer, H. Grüne berg, W. E. Heston, and G. D. Snell was organ ized. Spontaneous mutations occur very rarely and may alter the normal phenotype of a strain. The Mouse in Biomedical Research (Second Edition), https://doi.org/10.1016/B978-012369454-6/50017-0. However, many Genetically Engineered and Mutant Mice strain names have been revised to more clearly indicate the origin of a mutation (e.g., B6.129P2-Apoetm1Unc/J).

We have included additional information (strain type, control information, background and donor strains, and generation number) in the congenic strain detail both in our printed literature and on our website to more clearly delineate the genetic background. A visual guide to the genes influencing coat color. Congenic strains are produced by transferring a mutation from one genetic background to a specific inbred strain through repeated backcrossing. Note: In this example, the Cg is used to avoid suggesting that both mutations arose on DBA/J while showing that the misty (m) coat color marker and the diabetes (Leprdb) mutation are maintained in repulsion. Alleles are designated either by the chemical mutagen or by the abbreviation “tm” (targeted mutation), followed by a number and the laboratory registration code, and selection criteria superscripted to the gene symbol (e.g., Apoa1tm1Unc).

Find protocols, tips and other resources to assist you genotyping JAX® Mice. A key feature of mouse and rat nomenclature is the Laboratory Registration Code or Laboratory code, which is a code of usually three to four letters (first letter uppercase, followed by all lowercase) that identifies a particular institute, laboratory, or investigator that produced, and may hold stocks of, a mouse or rat strain. However, strains carrying mutations that have been backcrossed onto the background strain for at least five, but fewer than ten, generations are considered incipient congenic strains and may be useful in a variety of research areas. Copyright © 2007 Elsevier Inc. All rights reserved. The background of such congenics is frequently designated as “STOCK.” Formerly, most spontaneous and induced mutations transferred by backcrossing from a mixed background (e.g., either B6;129 or STOCK) to an inbred background were not described by conventional congenic nomenclature. The size of the segment and the possibility of transferred alleles on other chromosomes depend on the number of backcross generations.

Among these are the discovery of the underlying gene previously identified and known only by its mutant phenotype, the establishment of a gene as a member of a gene family with previously established gene family nomenclature, and the identification of orthologs among mouse, rat, and human where a common symbol is adopted for all three species. Oh no! The International Committee on Genetic Nomenclature of Rats, established in 1978 under the aegis of the International Council for Laboratory Animal Science (ICLAS), recognized the genetic nomenclature systems that had already been developed for the mouse and endorsed new nomenclature developed by ad hoc working parties: the new RT system for naming rat alloantigens and the revised esterase … From mouse strain nomenclature, you can determine genetic background, genetic modifications, who created the strain and who currently distributes it. *Mixed Strain Background = semicolon (;) Backcrossed to recipient inbred strain < 5 generations ** Congenic or Incipient Congenic = period (.) Site%Directed*Endonuclease*Mutagenesis:*Naming*Muta7ons* ABSTRACT* For example, epicardial and corneal mineralization was reported in severe combined immunodeficiency (SCID) mutant mice. The genetic background of many congenics is a mixture of C57BL/6J and a 129 substrain (designated either B6;129, B6;129P, or B6;129S; see explanation that follows on “Revised Nomenclature for Strain 129 Mice”). The International Mouse Strain Resource (IMSR) is funded by NIH grant HG000330. Research applications are included on strain data sheets in the JAX® Mice Database. Nomenclature follows the rules and guidelines established by the International Committee on … FORMER NAME: C57BL/6J-Tcrbtm1Mom. Oh no! The amount of donor strain DNA, both linked and unlinked to the differential locus, decreases with increasing generations of backcrossing. Note: This strain name should not be confused with that of a mutation maintained on a mixed B6;129P genetic background, where the strain abbreviations in the name are separated by a semicolon rather than a period (see Example 5). When a mutation occurs in a cloned candidate gene, the first letter of the gene symbol may remain upper case, and the inheritance pattern may be conveyed in the allele symbol. Inbred and HybridInbred* Spontaneous or. JAX® Mice bred and distributed from The Jackson Laboratory and Charles River Laboratories in Europe and Japan are bred using established practices that reduce the likelihood of genetic drift and therefore help … In 1994, the International Committee on Standardized Genetic Nomenclature for Mice voted to superscript a mutation’s symbol to the cloned gene symbol.
