About Pompe Disease

Pompe disease is a lysosomal storage disorder (LSD) caused by a deficiency in acid α-glucosidase (GAA, also called acid maltase). It is an autosomal recessive disorder with considerable phenotypic heterogeneity; both genders are equally affected. Pompe disease is classified into two broad categories based on the age of symptom onset – infantile-onset (up to age 12 months) and late-onset disease (post 12 months of age).1

Testing & Diagnosis

Patients with Pompe are characterised by having either no or substantially reduced acid α-glucosidase enzyme activity. However, diagnostic delays are common.Contributing factors include the rarity of the disorder, its wide clinical spectrum, signs and symptoms that overlap with those of other neuromuscular disorders, variable diagnostic approaches, lack of awareness of the clinical manifestations and difficulties in completing the diagnostic inventory.6
