PURPOSE In Pompe disease, a deficiency of acid α-glucosidase enzyme activity leads to pathologic accumulation of glycogen in tissues. Phenotype heterogeneity in Pompe includes an infantile form and late-onset forms (juvenile- and adult-onset forms). Symptoms common to all phenotypes include progressive muscle weakness and worsening respiratory function. Patients with late-onset forms of Pompe d...

INTRODUCTION Pompe disease is a rare, autosomal recessive disorder caused by deficiency of the glycogen-degrading lysosomal enzyme acid alpha-glucosidase. Late-onset Pompe disease is a multisystem condition, with a heterogeneous clinical presentation that mimics other neuromuscular disorders. METHODS Objective is to propose consensus-based treatment and management recommendations for late-ons...

BACKGROUND Neonatal screening for Pompe disease has been introduced in Taiwan and a few U.S. states, while other jurisdictions including some European countries are piloting or considering this screening. First-tier screening flags both classic infantile and late-onset Pompe disease, which challenges current screening criteria. Previously, advocacy groups have sometimes supported expanded neona...

Pompe disease/glycogen storage disease type II, is a rare, lysosomal storage disorder associated with progressive proximal myopathy, causing a gradual loss of muscular function and respiratory insufficiency. Studies of patients with late-onset Pompe disease have used endpoints such as the 6-minute walking test (6MWT) and forced vital capacity (FVC) to assess muscular and respiratory function du...

OBJECTIVE Myostatin and insulin-like growth factor 1 (IGF-1) are serum markers for muscle growth and regeneration. However, their value in the clinical monitoring of Pompe disease - a muscle glycogen storage disease - is not known. In order to evaluate their possible utility for disease monitoring, we assessed the levels of these serum markers in Pompe disease patients receiving enzyme replacem...

The diagnosis of Pompe disease in children and adults can be challenging because of the heterogeneous clinical presentation and considerable overlap of signs and symptoms found in other neuromuscular diseases. This review evaluates the use of muscle biopsy and other methods for the diagnosis and differential diagnosis of late-onset Pompe disease. Muscle biopsy is commonly used as an early diagn...

Introduction Pompe disease (glycogenosis II, acid maltase deficiency, OMIM 232300) is a treatable autosomal recessive disorder of glycogen metabolism caused by deficiency of the lysosomal enzyme acid alpha-glucosidase. A hallmark of Pompe disease is the presence of glycogen-loaded lysosomes. Pompe disease has frequently been misdiagnosed as other myopathies, such as polymyositis, and mistakenly...

Pompe disease is a rare autosomal recessive disorder caused by α-glucosidase deficiency. Lower airway involvement and management are rare in patients with late-onset Pompe disease. We describe the case of a 16-y-old girl with late-onset Pompe disease who presented with obvious progressive deterioration in respiratory function. Pulmonary hypertension was also apparent on echocardiography. She ha...

Pompe disease is due to a deficiency in acid-α-glucosidase (GAA) and results in debilitating skeletal muscle wasting, characterized by the accumulation of glycogen and autophagic vesicles. Given the role of lysosomes as a platform for mTORC1 activation, we examined mTORC1 activity in models of Pompe disease. GAA-knockdown C2C12 myoblasts and GAA-deficient human skin fibroblasts of infantile Pom...
