Lysosomal glycogen accumulation begins before signs of clinical weakness, so early muscle involvement may not be clinically detectable. Healthy myofibrils are eventually replaced by accumulated lysosomal and free muscle glycogen, further impairing muscle function.6

pompe disease spectrum



Pompe disease presents across a spectrum of severity and age of onset, which can occur in infancy, childhood, or adulthood. Pompe disease is classified into Infantile-onset (IOPD) or Late-onset Pompe disease (LOPD).4

Manifestations of Infantile-Onset Pompe Disease Can Include:7

Manifestations of Late-Onset Pompe Disease Can Include:4,7,8
