This is a Multisystem condition.
Glycogen Storage Disease Type IIIA, GSD IIIA
What is GSD IIIA?
Glycogen is the form in which our bodies store sugar: they are long, complex molecules that are primarily stored in the liver, heart, kidney, and muscle and are those tissues’ primary source of energy. In GSDs, glycogen accumulates to abnormal levels leading to enlargement and malfunction of these vital organs. Dogs with Type III GSD show milder signs as puppies including lower energy levels and poor weight gain.
What are the signs & symptoms that develop in affected dogs?
Affected dogs have "failure to thrive" including poor growth, lethargy, and mildly low blood sugars. They may be exercise intolerant and experience episodes of collapse.
When do signs and symptoms develop?
Signs appear around 14 months of age.
How do vets diagnose this condition?
Genetic and laboratory testing, including liver biopsy, are used to diagnose this disease.
How is this condition treated?
There is no treatment except supportive care for the clinical signs the affected dog develops.
What actions should I take if my dog is affected?
- Regulate the amount of activity affected dogs perform to prevent the most severe symptoms of this disease.
