IAMGSD is focused on:
“McArdle Disease and related disorders of muscle glycogen
where exercise intolerance is the major symptom.” 

From those severely affected to those who are high achieving –
IamGSD is here for everyone.


With IAMGSD's Objectives, we will one day see everyone with a muscle GSD have an early  diagnosis, receive good advice, access expert support and achieve an excellent quality of life.

With more people diagnosed with McArdle disease than all the other muscle GSDs put together, that GSD is our initial focus. In time we will learn more about the other muscle GSDs and improve our coverage.

If you would like to contribute to our knowledge, or improve our offerings for a specific GSD, please send us a note via our contact form.

GSD2, Pompe Disease, is also a lysosomal disorder. It is rather different to other muscle GSDs.  We defer to the long established International Pompe Association.

What is IamGSD?

We are a patient-led international group encouraging efforts by research and medical professionals, national support groups and individual patients worldwide.

What is Muscle GSD?

Human bodies make glucose from carbohydrates. Excess glucose is stored as glycogen in our muscles and liver. Muscle glycogen storage disease is when our muscles cannot convert their glycogen back into glucose to power our muscles.
