Through outpatient surgery a small piece of muscle is removed (usually from the arm or leg) and evaluated with a variety of biochemical tests. Researchers are attempting to match results of muscle biopsies with DNA tests to better understand how variations in the genome present themselves in tissue anomalies.
Studying a small piece of muscle tissue taken from an individual during a muscle biopsy can sometimes tell a physician whether a disorder is muscular dystrophy and which form of the disease it is. In Duchenne and Becker muscular dystrophy, a muscle protein called dystrophin is either missing, deficient or abnormally formed. This protein can be examined in the muscle sample.
