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.

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).
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.

This strain is maintained by mating homozygous females to hemizygous males (X-linked).
When using the X linked muscular dystrophy 4 mouse strain in a publication, please cite the originating article(s) and include JAX stock #002378 in your Materials and Methods section.
We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
