Alpha-1 Antitrypsin Disease Cohort: Longitudinal Biomarker Study of Disease

NIH-funded research Columbia University Health Sciences · NIH-11192245

This project follows people with alpha-1 antitrypsin deficiency to find blood, imaging, and genetic markers that link to lung disease and its course.

What this research studies

You would join a group of people with alpha-1 antitrypsin deficiency who are followed over time. Participants provide medical history and clinical data and may give blood, serum, or plasma samples, undergo chest imaging and lung function tests, and share genetic information so researchers can look for biomarkers and genotype–phenotype links. The team will build a prospective clinical cohort integrated with the Alpha-1 Foundation contact registry and invite selected participants into more detailed biomarker studies. Over time the project aims to map how different genetic types and biological markers relate to disease progression and clinical outcomes.

Who could benefit from this research

Good fit: Adults with confirmed alpha-1 antitrypsin deficiency (for example low AAT levels or known pathogenic genotypes), with or without COPD, who can provide samples and clinical information are ideal candidates.

Not a fit: People without alpha-1 antitrypsin deficiency or those seeking an immediate therapy rather than long-term biomarker information are unlikely to benefit directly.

Why it matters

Potential benefit: If successful, this work could produce tests that help predict lung disease progression in people with AATD and guide who might benefit from specific treatments.

How similar studies have performed: There are existing registries and cohort efforts in alpha-1 disease, but validated biomarkers that reliably predict progression remain limited, so this builds on prior work with still-unproven biomarker goals.
