Strain Information

Former Names C57BL/6J-rcw3J/J    (Changed: 14-DEC-07 ) Type Coisogenic; Mutant Strain; Spontaneous Mutation; Additional information on Genetically Engineered Mutant Mice. Species laboratory mouse

Description
Mice homozygous for the recoil wobbler 3 Jackson mutation have a slightly smaller body size and a wobbly gait, causing loss of balance when walking, usually visible by 2 weeks of age.

Development
The recoil wobbler 3 Jackson mutation arose spontaneously in 2004 in C57BL/6J at The Jackson Laboratory when that inbred was at generation F224. It has been maintained by sibling mating and reached generation F224+4 in June 2005.

        C57BL/6J-Grm1^rcw-3J/J

• behavior/neurological phenotype
• ataxia (MGI Ref ID J:98757)
  • by 2 weeks of age, mutant mice exhibit a side-to-side wobble when walking; this movement often throws them off balance
• growth/size phenotype
• decreased body size (MGI Ref ID J:98757)
  • mutant mice are slightly but noticeably smaller than unaffected littermates by 2 weeks of age
• nervous system phenotype
• *normal* nervous system phenotype (MGI Ref ID J:98757)
  • a routine pathology screen of two 12 week old mutant mice identified no central nervous system (CNS) or other lesions

Genes & Alleles

Gene & Allele Information

Allele Symbol		Grm1rcw-3J
Allele Name		recoil wobbler 3 Jackson
Allele Type		Spontaneous
Strain of Origin		C57BL/6J
Gene Symbol and Name		Grm1, glutamate receptor, metabotropic 1
Chromosome		10
Gene Common Name(s)		G protein coupled receptor, family C, group 1, member A; G protein-coupled receptor, family C, group 1, member A; GPRC1A; GRM1A; Gprc1a; MGLUR1; MGLUR1A; mGlu1; neuroscience mutagenesis facility, 373; nmf373; rcw; recoil wobbler; wobbles; wobl;
Molecular Note		This mutation was shown to be an allele of rcw by a complementation test versus recoil wobbler 2 Jackson. A G1385A transition was identified which resulted in a G337E amino acid substitution. This is identical to the mutation in Grm1rcw-4J and both probably result from a single mutational event.

Supply Notes

Cryopreserved Embryos This strain is also available as cryopreserved embryos from our Repository. Orders for cryopreserved embryos are supplied subject to a signed agreement that must be returned to the Customer Service Department after order placement. Experienced technicians at The Jackson Laboratory have recovered frozen embryos of this strain successfully. We will provide you enough embryos to perform two embryo transfers. The Jackson Laboratory does not guarantee successful recovery at your facility. For complete information on purchasing embryos from our repository, please visit our Cryopreserved Embryos web page. Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 or 1-207-288-5845. This strain is included in the Mouse Mutant Resource collection.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX^® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX^® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX^® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
