DMD and Duchenne muscular dystrophy: For example, many shortened versions of the Duchenne muscular dystrophy gene (DMD; 2.3 Mb; 79-exons; 3685 amino acids; 11,055 bp) do not rescue the Duchenne muscular dystrophy phenotype in muscle cells except for the micro-dystrophin for which was reported a milder clinical phenotype [183,184].
