Background Strain C57BL/6J
Donor Strain 129S2 via D3 ES cell line
 
Donating Investigator IMR Colony,   The Jackson Laboratory

Description
Mice homozygous for the En1tm1Alj targeted mutation die shortly after birth. They are missing the third and fourth cranial nerves as well as most of the colliculi and cerebellum. The brain phenotype can be less severe depending on the genetic background. There is also a disruption of the dorsal/ventral patterning of the limb paws, a disrupted sterum, and truncation of the 13th ribs. Deletion of mid-hindbrain tissue may be seen as early as embryonic day 9.5.

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.
