A novel SNaPshot assay to detect the mdx mutation.

The mdx mouse is an animal model for Duchenne muscular dystrophy (DMD). In order to evaluate possible treatments and to carry out genetic studies, it is essential to distinguish between mice that carry the dystrophic (mutant) or wild-type (wt) allele(s). The current amplification-resistant mutation system (ARMS) assay is labor intensive and yields false negatives, which reduces its efficiency as a screening tool.
