This spontaneous mutation of Dmd is one several Dmdmdx revertants and exhibits muscle fiber necrosis, fibrosis and centrally nucleated skeletal muscle fibers. This allele has 10-fold fewer revertants than mdx-2Cv and mdx-3Cv and may be useful in studies of muscular dsystrophy.

Description
The Dmdmdx-4Cv and Dmdmdx-5Cv strains have 10 times fewer revertants than the Dmdmdx and Dmdmdx-2Cv strains as viewed in quadricep cross-sections. This is not attributable to genetic background or viral infections. These reversion rate differences may be attributable to differences in the location of the point mutation. The large number of revertants in Dmdmdx mutants has complicated the analysis of gene or cell therapies. These mutants are more useful for this purpose. All these strains are also hemizygous for Hprta and Pgk1a (both are on the X chromosome).

Development
This strain was created in the laboratory of Verne M. Chapman. A C57BL/6Ros female was crossed to a male of strain C3Ha.X25, a double congenic strain carrying Pgk1a (from a wild Mus musculus musculus mouse trapped in Denmark) and Hprta (from Mus castaneus) on a C3H/HeHa background. F1 or F2 male progeny of this cross were treated with n-ethylnitrosourea (ENU) and crossed to C57BL/10Sn-Dmdmdx/+ females. Female offspring of these crosses that exhibited consistently elevated plasma creatine kinase levels and that carried the X-chromosome markers of their mutagenized male progenitors were bred to C57BL/10Sn-Dmdmdx/Y males. Transmission to male progeny of the elevated plasma CK phenotype and failure of the suspected new mutations at the Dmd locus to complement the classical mdx mutation identified four new mutations of Dmd, called Dmdmdx-2-5Cv . Each of these new mutations was subsequently backcrossed onto C57BL/6Ros.

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.
