There has been a recent explosion in the identification of neuromuscular diseases caused by mutations in genes that affect carbohydrate metabolism or protein glycosylation. A number of these findings relate to defects in the glycosylation of
dystroglycan.
Dystroglycan is an essential component of the dystrophinglycoprotein complex, and aberrant glycosylation of
dystroglycan is associated with multiple forms of muscular dystrophy in mice and humans. We review the evidence that defects in dystroglycan glycosylation cause muscular dystrophy. In addition, we review evidence that glycobiology is important in other disorders that affect muscle, including hereditary inclusion body myopathy type II and congenital disorders of glycosylation. Finally, we discuss the long-term potential of glycotherapies for muscle disorders.
