These Atf2tm1Glm targeted mutant mice exhibit decreased postnatal viability and growth, with a defect in endochondral ossification at epiphyseal plates similar to human hypochondroplasia.

Targeted (Hypomorph) | Atf2 | activating transcription factor 2 |
Mice homozygous for this mutation show decreased postnatal survival. Many of the mice die within the first 2 days of life or at the time of weaning. The growth of the surviving homozygous mice is impaired. Homozygous mice are hyperactive, display a very fine tremor, show an "exaggerated stretching of the hind limbs upon awakening", and have decreased grasping ability in the hind limbs. Homozygous mice have "increased numbers of microglia in the corpus callosum and other white matter tracts", as well as "larger, often distorted myelinated axons" in the spinal cord. Over half of homozygous mice develop a periocular inflammation consisting of neutrophils and lymphocytes.

Allele Synonym(s) | ATF-2 -; ATF-2m |
Gene Symbol and Name | Atf2, activating transcription factor 2 |
Gene Synonym(s) | |
Strain of Origin | 129S2/SvPas |
Chromosome | 2 |
Molecular Note | A neomycin cassette was inserted into sequences corresponding to position 899 of the encoded mRNA (in the exon encoding amino acids 277-326). Although no full length protein is observed, these mice are hypomorphic as they express low levels of a novel spliced protein. |
Mutations Made By | Dr. Laurie Glimcher, Dana Farber Cancer Institute |
The expected coat color is albino.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
