Diagnostic Services for
Pompe Disease

A proven and certified diagnostic service delivering reliable results for Pompe Disease diagnosis (glycogen storage disease type II) using advanced analytical techniques including enzyme, and genetic testing.

Premium diagnostic services for Pompe Disease.
From enzyme to genetic confirmation.

Path to Pompe Disease Diagnosis

Our service is ideal for the identification of Pompe Disease in at-risk patients showing specific clinical symptoms or for an individual or family member who has a family history of Pompe Disease.

Testing is fast and safe using Dried Blood Spot (DBS) cards. This simple and minimally invasive technique supplies enough sample for biochemical testing and in most cases genetic confirmation testing as well.

Quality:

Fully validated and accredited according to the highest quality standards for Medical Laboratories (ISO 15189).

 

Methodologies used:

  • Enzyme assays by Clinical Mass Spectrometry.
  • Genetics by Sanger and Next-Generation Sequencing platforms.
Path to Pompe Diagnosis

Available enzymatic and biomarker tests:

Enzyme:
GAA (acid α-Glucosidase)

Available genetic tests:

Gene Associated disease(s) OMIM # Inheritance
GAA Pompe (GSD II) 606800 AR

Differential diagnosis options: 

Other disease affecting muscle function and growth such as 5q-Spinal Muscular Atrpohy (SMA) and Limb-girdle muscular dystrophies (LGMD) are a differential diagnosis of Pompe disease. Visit our Muscle Disorders page for more information.

About Pompe Disease

What is Pompe Disease?

Pompe Disease, also known as glycogen storage disease type II or acid maltase deficiency (AMD), is part of a group of lipid storage disorders affecting glycogen metabolism in lysosomes. Pompe disease is an inherited autosomal recessive genetic disease resulting from the reduced or absent activity of the enzyme acid α-Glucosidase (GAA).

There are two main forms of Pompe disease

  • Classic infantile – Characterized by a total lack of GAA activity and by a rapid buildup of glycogen in skeletal muscle and heart. This form is the most severe and while symptoms may not be apparent at birth, the disease usually presents within the first three months of life with rapid, progressive muscle weakness (floppy infants), diminished muscle tone (hypotonia), respiratory insufficiency, and hypertrophic cardiomyopathy. These problems together culminate in cardio-respiratory failure within the first 2 years of life.
  • Childhood/adult (late onset) – Childhood and adult Pompe disease is associated with progressive weakness of mainly the proximal muscles (limb-girdle, upper arms, and upper legs), and varying degrees of respiratory weakness due to dysfunction of the diaphragm and intercostal muscles. As a result of the combination of these serious symptoms, affected individuals may become wheelchair and/or ventilator dependent.

Which mutation causes an enzyme deficiency?

Pompe Disease is caused by different mutations in the GAA gene. This gene is responsible for coding the GAA enzyme which metabolizes glycogen. Accumulation of the glycogen, occurring primarily in skeletal muscle, smooth muscle, and cardiac muscle results in the clinical presentation of the disease.

Are there diseases similar symptoms to Pompe Disease?

Because of the progressive muscle weakness associated with Pompe disease, it shares symptoms of other muscular disorders such as Spinal Muscular Atrophy or Limb-girdle muscular dystrophy. Investigation of these disorders should be considered with individuals showing non-specific symptoms.

Clinical Symptoms:

Common symptoms include rapidly progressive muscle weakness (floppy infants), diminished muscle tone (hypotonia), respiratory insufficiency, and hypertrophic cardiomyopathy.
