False statement about Becker muscular dystrophy

(C) Gene involved is myosin # Becker muscular dystrophy (Benign pseudohypertrophic muscular dystrophy) is an X-linked recessive inherited disorder characterized by slowly progressive muscle weakness of the legs and pelvis.> It is a type of dystrophinopathy, which includes a spectrum of muscle diseases in which there is insufficient dystrophin produced in the muscle cells, resulting in instability in the structure of muscle cell membrane.> This is caused by mutations in the dystrophin gene, which encodes the protein dystrophin.> Becker muscular dystrophy is related to Duchenne muscular dystrophy in that both result from a mutation in the dystrophin gene, but in Duchenne muscular dystrophy no functional dystrophin is produced making DMD much more severe than BMD.> Elevated CPK levels are more common at younger ages and decreases later in life.> A muscle biopsy (immunohistochemistry or immunoblotting) or genetic test (blood test) confirms the diagnosis.
