The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
| Signs and Symptoms | Approximate number of patients (when available) |
| Autosomal recessive inheritance | - |
| Intraalveolar nodular calcifications | - |
| Onset | - |
| Progressive pulmonary function impairment | - |
| Restrictive deficit on pulmonary function testing | - |
| Slow progression | - |
Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
The Rare Lung Diseases Consortium: Molecular Pathway-Driven Diagnostics and Therapeutics for Rare Lung Diseases is an integrated group of academic medical centers, patient support organizations, and clinical research resources dedicated to conducting clinical research involving pulmonary alveolar proteinosis, Hermansky-Pudlak Syndrome, and Lymphangioleiomyomatosis. A pilot project program supports research into other rare lung diseases that complement the main research projects.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.
