Overview
Other diagnostic studies for glycogen storage disease type 2 (GSD type 2) include electromyography and molecular genetic testing. Electromyography findings suggestive of GSD type 2 include myopathy.
Other Diagnostic Studies
Electromyography
- Electromyography may be helpful in the diagnosis of glycogen storage disease type 2 (GSD type 2). Findings suggestive of GSD type 2 include:[1][2]
Molecular genetic testing
- Molecular genetic testing shows biallelic pathogenic variants in gene responsible for deficiency of lysosomal acid alpha glucosidase enzyme (GAA) for patients with GSD type 2.[3]
- Methods for molecular genetic testing include:
