Type JAX® GEMM® Strain - Mutant Stock Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Spontaneous Mutation Species laboratory mouse Generation N6F1 Strain Description
Mice homozygous for the teetering spontaneous mutation (tn) die between 5 and 6 weeks of age. Homozygous mutant mice are first recognizable at 25 to 30 days by their stiff, slow, unstable movements and their growth retardation. They may assume and maintain unusual postures. Occasionally they have running "fits". Just prior to death they look emaciated and lie on their sides with all limbs extended. In the brainstem and spinal cord there is dysgenesis of selective regions including the pons, trapezoid body, olivary and fastigial nuclei, and the pyramidal tract. There is also progressive Purkinje cell loss.Strain Development
The teetering mutation spontaneously arose in the C3H/HeJ inbred strain in 1959 at The Jackson Laboratory. The mutation was backcrossed to C57BL/6J six times and maintained as a sibling mating. In 1979, a high incidence of hydrocephalus in the colony prompted an outcross to B6C3FeF1/J a/a. This strain was cryopreserved as embryos in 1986.

Cryorecovery of Strains Needing Progeny Testing. 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 untested males and two untested females (two pairs) will be recovered, 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 overall recovery time to approximately 25 weeks. However, all pups recovered will be sent. Progeny testing is required to identify the genotype of mice of this strain, as a genotyping assay is not available. This type of testing involves breeding the recovered animals and assessing the phenotype of the offspring in order to identify animals carrying the mutation of interest. We can perform the progeny testing for you as a service or we can ship all recovered animals (at least two untested pairs) to you for progeny testing at your facility. If you perform the progeny testing, there is NO guarantee that a carrier will be identified. If we perform progeny testing as a service, additional breeding time will be required. In this case, when a male and female (one pair) are identified that carry the mutation, they and their offspring will be shipped. Delivery time for strains requiring progeny testing often exceeds 25 weeks and may take 12 months or more due to the difficulties in breeding some strains. The progeny testing cost is in addition to the recovery cost and is based on the number of boxes used and the time taken to produce the mice identified as carrying the mutation. Please note that identified 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.
