Abstract

Pompe disease is a glycogen storage disease caused by a deficiency in acid α-glucosidase (GAA) – a hydrolase necessary for the degradation of lysosomal glycogen. This deficiency in GAA results in muscle and neuronal glycogen accumulation, which causes respiratory insufficiency. Pompe disease rodent models provide a means of assessing respiratory pathology and are important for pre-clinical studies of novel therapies that aim to treat respiratory dysfunction and improve quality of life. This review aims to compile and summarize existing manuscripts which characterize the respiratory phenotype of Pompe rodent models. Manuscripts included in this review were selected utilizing specific search terms and exclusion criteria. Analysis of these findings demonstrate that Pompe disease rodent models have respiratory physiological defects as well as pathologies in the diaphragm, tongue, phrenic and hypoglossal motor nucleus, phrenic and hypoglossal nerves, neuromuscular junctions, and airway smooth muscle and higher order respiratory control centers. Overall, the culmination of these pathologies contributes to severe respiratory dysfunction, underscoring the importance of characterizing the respiratory phenotype while developing effective therapies for patients.
