Duchenne muscular dystrophy is one of the most common dystrophinopathies known. (who.int)

If this is the case, your doctor may recommend a muscle biopsy to look for the telltale signs of Duchenne in muscle cells. (everydayhealth.com)

Future work is aimed at further delineating the relationship of dystrophin and the circadian clock, and downstream mechanisms including miR-484. (mdaconference.org)
