Overview

Glycogen storage disease type II may be classified according to the age of onset and presence of cardiomegaly into 2 subtypes including infantile-onset Pompe disease (IOPD) and late-onset Pompe disease (LOPD).

Classification

Glycogen storage disease type II may be classified according to the age of onset and presence of cardiomegaly into 2 subtypes:[1][2][3][4][5]

Type of GSD type 2 Age of onset
Infantile-onset Pompe disease (IOPD) Classic form Age of onset before 12 months with cardiomyopathy
Non-Classic form
Late-onset Pompe disease (LOPD) Childhood/Juvenile form
  • Age of onset before 12 months without cardiomyopathy
  • Age of onset after 12 months
Adult form
