Résumé

Muscle glycogenosis (GSDs) is an important group of potentially treatable inherited muscle disorders affecting children and adults.

Major advances have been achieved in the diagnosis of these disorders over the past years thanks to improvements in biochemical and molecular techniques.

Better understanding of the phenotypes and clinical course of the various glycogenosis has led to improved multidisciplinary approach to care, follow-up and improved outcomes.

Depending on the aetiologies, various therapeutic approaches are available such as specific diets, enzyme replacement therapy, exercise, and novel drugs or gene therapy are in the pipeline. 

LEARNING OBJECTIVES

• To describe the pathophysiology and clinical features of the main muscle glycogenosis in children and adults (McArdle disease, Pompe disease, GSD3), but also less frequent glycogenosis (polyglucosans storage myopathies and glycolysis disorders) and their differential diagnosis. • To describe the main diagnostic tools (exercise tests, muscle biopsy, biochemical and molecular analysis) and to discuss their respective positions in the diagnostic work-up in 2023. • To provide guidance for diagnosis and management of muscle glycogenosis. • To describe current treatments and emerging therapies.

TARGET AUDIENCE

This course is aimed at paediatricians, neurologists, neuromuscular specialists, internists, cardiologists, geneticists, biochemists, and other clinicians and scientists willing to improve their knowledge in the diagnosis and treatment of muscle glycogenosis + differential diagnosis with other metabolic myopathies.
