SGCG and Duchenne muscular dystrophy: The presence of shortened telomeres was observed in DMD (Duchenne Muscular Dystrophy) and LGMD2C (limb-girdle muscular dystrophy type 2C) patients [137, 138] and in Dmdmdx mice [139]. Dmdmdx mice lacking telomerase activity develop a phenotype more faithful to muscular dystrophy in humans, including a worsening with aging [140].
