Mutations in the DMD gene can cause a muscle-wasting disorder, called Duchenne muscular dystrophy, or its milder form, Becker muscular dystrophy.Keywords: becker muscular dystrophy,dmd gene,chromosome x,muscle cells,dystrophin,cell walls,mutations,leaks,protein,shape.This work by Cold Spring Harbor Laboratory is licensed under a Creative Commons Attribution-Noncommercial-No Derivative Works 3.0 United States License.hen this protein is missing, muscle cells literally explode as material from outside the cell walls leaks in raising cell pressure.
