Scientists launch deep dive into rare bleeding and lung disease
NCT ID NCT00001456
First seen Jun 26, 2026 · Last updated Sep 10, 2026 · Updated 17 times
Summary
This study aims to learn more about Hermansky-Pudlak Syndrome (HPS), a rare inherited disease that causes light skin/eye color, bleeding problems, and often deadly lung scarring. Researchers will follow 600 people with HPS and their family members to track how the disease progresses and collect samples for genetic and lab studies. The goal is to better understand the full range of complications and find clues for future treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could reveal the underlying causes of HPS complications, pointing toward potential treatments or management strategies.
- What could go wrong
- This is an observational study, not a treatment trial. It may not directly lead to new therapies, and results may take years to translate into clinical practice.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
* INCLUSION CRITERIA Persons with HPS or family members who are their caregivers aged 1-80 years are eligible to enroll in this protocol. The diagnosis of HPS is based upon a paucity or deficiency of platelet dense bodies on whole mount electron microscopy or the identification of pathogenic variants in HPS genes by genetic testing. Some persons who have not been diagnosed with HPS may be admitted to the protocol based upon the presence of albinism and a platelet storage pool deficiency. Subjects participating only in the HPS Symptom Questionnaire will be at least 18 years of age. EXCLUSION CRITERIA Pregnant women and adults who are unable to provide consent are excluded.
