Infantile Onset Glycogen Storage Disease Type 2: Case Report

Glycogen storage disease type 2 (Pompe’s disease) is an autosomal recessive, fatal glycogen storage disease presenting with hypotonia and muscle weakness. It is known that deficiency of lysosomal acid alpha-glucosidase (acid maltase) leads to progressive generalised myopathy, cardiomyopathy and death in early infancy because of respiratory muscle weakness. Excessive undegradable intracellular glycogen deposition plays a role in the pathogenesis of the disease. Here we report a 3.5 month-old girl presenting with respiratory failure due to pneumonia and hypotonia, who was later diagnosed as Pompe disease.
