Recommendation
Testing for Pompe disease must be done if any one specialty-specific symptom plus elevated CK/LDH/ALT/AST or a family history of unexplained muscle weakness is present
*The age of patients with pediatric/juvenile LOPD ranges from 1 to 17 years; #The age of patients with adult LOPD is usually 18 years and above.
