C57BL/10-mdx mice were backcrossed to DBA/2J inbred mice for several generations by Jackson Labs, using a speed congenics approach to generate the DBA/2J-congenic strain (DBA/2J-mdx). The skeletal muscle and cardiac phenotype is more severe than that of C57BL/10ScSn-Dmdmdx/J. This may be a useful model for preclinical drug testing. DBA2/J mice are the wild-type controls for this model. We have systematically phenotyped this model at multiple age groups.
