Related Genotype: a/aStrain Description
Mice homozygous for the wasted spontaneous mutation (Eef1a2wst) can be recognized at 20 days of age by tremor and uncoordinated body movements. Homozygous mutant mice develop progressive paralysis and do not survive beyond 30 days. They have marked lymphoid hypoplasia in the spleen, thymus, lymph nodes, and peripheral blood. Wasted mice have a severely reduced number of IgA plasma cells in the entire large and small intestines, but the number of such cells in the spleen and the level of serum IgA are normal.Neuronal degeneration occurs in the brain and spinal cord. Spinal cord abnormalities are preceded by gliosis following along a rostrocaudal gradient. Thoracic/abdominal muscles exhibit a progressive denervation of muscle fibers, with progressive asynchronous retraction of motor nerve terminals. (Newbery HJ, et al. 2005)

| General Note | The enzymatic specific activity of ADA (which takes into account the reduced tissue weights of wasted mice) is increased in the spleen and cerebellum but decreased in the thymus of these mutants (J:12932). Homozygotes are recognized at about 20 days witha tremor, uncoordinated body movements, and the beginning of body weight loss. They develop progressive paralysis and do not survive beyond 30 days of age (J:6766). Wasted mutant mice have marked lymphoid hypoplasia in the spleen, thymus, lymph nodes,and peripheral blood. Thymocytes from these animals show an increase of in situ apoptosis, which probably accounts for the thymus hypoplasia (J:50410). The relative proportion of T and B cells is not affected. In the central nervous system there is degeneration of Purkinje cells and focal demyelination in the cerebellar cortex and ventral columns of the spinal cord (J:6766). Wasted mice show some similarities to human ataxia telangiectasia (AT; MIM 208900; human gene, ATM; mouse gene, Atm) (J:6766),but there are also numerous differences. Eef1a2ws mice have a marked increase in spontaneous and gamma radiation-induced chromosomal abnormalities in bone marrow, as there is in AT (J:6766, J:8276). But the mutant mice lack the increased sensitivity of spleen cells to killing by ultraviolet radiation (J:20567), the increased sensitivity of cultured fibroblasts to killing by X or gamma radiation (J:8348, J:13960), and the increased post-irradiation inhibition of DNA synthesis (J:7561) characteristic of AT. In addition, the immunological defects of wasted mice differ considerably from those in human AT (J:8288). Wasted mice have a severely reduced number of IgA plasma cells in the entire large and small intestine, but the level of such cellsin spleen and the level of serum IgA are normal (J:7903). The mutants also show an extensive cytokine imbalance of many immunologically relevant gene products (IL5, IL1, IL2, IFNG, and TGFB1) which may trigger the wasted pathogenesis (J:19431). The overlapping similarities between AT and wasted, however, have suggested the possibility that Eef1a2 and Atm may be involved in a common pathway, such as a signal-transduction pathway that regulates protein synthesis (J:48050). In fact Eef1a2ws mice show abnormal expression of the proliferating cellular nuclear antigen (PCNA) in the thymus (J:37955). | ||
| Molecular Note | The mutation is a 15.8kb deletion that removes the promoter region and first noncoding exon of the gene. [MGI Ref ID J:47466] | ||

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. Please contact Customer Service for more information on the cost of progeny testing for a strain: Tel: 1-800-422-6423 or 1-207-288-5845.
