This study finds a direct correlation between LARGE-glycan extension on dystroglycan and the protein’s capacity for extracellular matrix ligands; in regenerating mouse muscle, short LARGE-glycan polysaccharides cause various defects, including muscle dysfunction and a predisposition to dystrophy, and in muscular dystrophy patients, increased clinical severity of disease corresponds to shorter LARGE-glycans.
