Pompe Disease and Autophagy: Partners in Crime, or Cause and Consequence?

Pompe disease or glycogen storage disease type II (OMIM: 232300) is a lysosomal storage disorder resulting from a partial or total lack of acid alphaglucosidase, which may produce muscle weakness, gait abnormalities, or even death by respiratory failure. In the last decade, autophagy has been proposed as a mechanism involved in the severity of symptoms related to this disorder and as a potential therapeutic target to alleviate disease progression. This review summarizes the relationship between autophagy and Pompe disease, including what information has been recently discovered and what remains unclear.
