a protein normally found in muscle tissue: its absence or deficiency has been linked to muscular dystrophy
Origin of dystrophin; from dystroph(y) + -in
A large structural protein found in small amounts in the plasma membranes of muscle fibers. The absence of dystrophin due to a genetic mutation causes Duchenne's muscular dystrophy; insufficient dystrophin causes Becker muscular dystrophy.
Origin of dystrophindystroph(y) + –in.
