What is the Glycogen Storage Disease Type Ia Program?
This program provides sponsored, no-charge genetic testing for individuals suspected of having Glycogen Storage Disease Type Ia (GSDIa).
GSDIa is a rare inherited metabolic disorder that results in the buildup of glycogen in the body's cells and an inability to regulate and maintain normal blood sugar levels. It is caused by variants in the G6PC1 gene.
