Abstract

Lysosomal myopathies are hereditary myopathies characterized morphologically by the presence of autophagic vacuoles. In mammals, autophagy plays an important role for the turnover of cellular components, particularly in response to starvation or glucagons. In normal muscle, autolysosomes or autophagosomes are typically inconspicuous. In distinct neuromuscular disorders, however, lysosomes become structurally abnormal and functionally impaired, leading to the accumulation of autophagic vacuoles in myofibers. In some instances, the accumulation of autophagic vacuoles can be a prominent feature, implicating autophagy as a contributor to disease pathomechanism and/or progression. At present, there are two disorders in the muscle that are associated with a primary defect in lysosomal proteins, namely Pompe disease and Danon disease. This review will give a brief discussion on these disorders, highlighting the role of autophagy in disease progression.
