The human Branchio-Oto-Renal Syndrome is generally a dominant disorder with incomplete penetrance and variable expressivity resulting from null mutations in the EYA1 gene. The mouse Eya1bor allele is primarily a recessive hypomorphic mutation. Nevertheless, homozygous mice with this hypomorphic allele offer a good model for Branchio-Oto-Renal Syndrome. The phenotype of Eya1bor/Eya1bor mice parallels that of the human Branchio-Oto-Renal Syndrome and both are thought to result from reduced gene dosage. The Eya1bor/Eya1bor mice are deaf and their behavior is marked by circling and head-bobbing. They lack all but the most basal one-quarter of the cochlea, and the organ of Corti is completely absent. They have foreshortened, narrower semicircular canals and in some the common crus is incomplete. Their kidneys are absent or dysmorphic with greater severity generally on the left side. Fewer homozygotes than expected are born. During mapping crosses using CAST/Ei and C3H/HeJ, it was found that genetic background impacts both the kidney and inner ear phenotypes, and modifier genes in humans also may impact the severity of Branchio-Oto-Renal-Syndrome. (Johnson et al., 1999)Mice heterozygous for a targeted mutation of Eya1 display a phenotype with hearing loss, renal defects (at low penetrance), and developmental disorders, paralleling the phenotype of mice homozygous for Eya1bor. TUNEL analysis on developing ears of the Eya1 targeted mutant mice revealed an increase in apoptotic cells in the otic vesicle at embryonic day 10.5. (Xu et al., 1999.)

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.

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.Ordering and Purchasing Information
