PAP Foundation

The PAP Foundation is a non-profit patient advocacy organization dedicated to finding a cure and to improving the lives of those affected by Pulmonary Alveolar Proteinosis (PAP). Through advocacy and collaboration, we promote research on PAP and provide information and support for PAP patients, healthcare professionals, and the public. We are pleased to be a resource of information about PAP. However, the information provided here is not, nor is it intended to be, medical advice and should never take the place of advice from your personal health care provider.

Pulmonary Alveolar Proteinosis (PAP) is a life-threatening lung disorder where naturally occurring surfactant abnormally builds up in the tiny air sacs (alveoli) of the lungs. This build-up blocks air from entering alveoli and prevents oxygen from passing through into the blood, resulting in symptoms ranging from mild to severe and life-threatening.
