Pompe Disease Enzyme Test



Pompe disease is an inborn error of glycogen metabolism due to a deficiency of acid alpha-glucosidase. In the infantile form, clinical symptoms include hypotonia, failure to thrive, and progressive hypertrophic cardiomyopathy. The late-onset form can present from childhood through adulthood with progressive muscle weakness and respiratory dysfunction. The physical disability is varied and does not directly correlate with chronological age. Treatment is available for symptomatic individuals with Pompe disease.
