Glycogen Storage Disease Type IIIA, 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.
