Strain Information
Former Names B6C3FeF1 a/A-Eya1bor/J (Changed: 18-FEB-05 ) Type Mutant Strain; Additional information on Genetically Engineered and Mutant Mice. Type *F1 Hybrid; Additional information on Hybrid Strains. Visit our online Nomenclature tutorial. Species laboratory mouse Generation N3 Description
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.)

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
