Are there tests that detect carriers of muscular dystrophy?
Yes. MDA-supported researchers have developed accurate protein and DNA-based carrier detection tests for families affected by Duchenne and Becker muscular dystrophies. Carrier testing for other muscular dystrophies is being developed. Carriers of Duchenne and Becker dystrophies can sometimes be identified by a high blood creatine kinase (CK) level, indicating that some muscle destruction is going on (usually not enough to cause symptoms). This kind of test isn’t as specific as looking at DNA or at a protein known to be specifically associated with a dystrophy. The genetic counselor at your MDA clinic is a valuable source of information about DNA-based diagnostic tests.
