Detailed Description

WAS-deficient mice are viable and fertile. Mutant mice show normal lymphocyte development, serum immunoglobulin (Ig) levels and antibody responses. However, peripheral blood lymphocyte counts and platelet numbers are reduced in these mice. Development of chronic colitis is also observed. In vitro, WAS-deficient T cells show markedly impaired proliferative responses to anti-CD3e mediated stimulation. The Was gene is X-linked, so hemizygous males are WAS deficient.

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

Disease Terms

Model with phenotypic similarity to human disease where etiologies involve orthologs. Human genes are associated with this disease. Orthologs of those genes appear in the mouse genotype(s).

Model with phenotypic similarity to human disease where etiologies are distinct. Human genes are associated with this disease. Orthologs of these genes do not appear in the mouse genotype(s).
