International Pompe Day

April 15, 2021

Pompe disease is an inherited disorder caused by the buildup of a complex sugar called glycogen in the body's cells. The accumulation of glycogen in certain organs and tissues, especially muscles, impairs their ability to function normally. Researchers have described three types of Pompe disease, which differ in severity and the age at which they appear. These types are known as classic infantile-onset, non-classic infantile-onset, and late-onset.The classic form of infantile-onset Pompe disease begins within a few months of birth.
The non-classic form of infantile-onset Pompe disease usually appears by age one.
The late-onset type of Pompe disease may not become apparent until later in childhood, adolescence, or adulthood.
