Cause of Pulmonary Glycogenosis
- The cause is unknown.

Signs and Symptoms
Symptoms are only seen in young babies. Babies usually show symptoms at birth or soon after birth. Symptoms include:
- Fast breathing (called tachypnea)
- Sinking in of the areas below the ribs, between the ribs, and in the neck with breathing (called retractions)
- Abnormally low amount of oxygen in the blood (called low oxygen saturations or hypoxemia)
- Some babies may have pulmonary hypertension
Diagnosis of Pulmonary Glycogenosis
- Visits with a lung doctor (called a pulmonologist)
- Chest CT scan
- Lung biopsy is usually needed.
Treatment for Pulmonary Glycogenosis
- Additional oxygen (usually needed)
- Intravenous (IV) steroids if needed
- Additional nutrition to help gain weight and grow if needed
- Flu shot every year to lower the chance of getting infections
