Long-term lung health after very early birth
Long-term Endotypes of Prematurity Associated Respiratory Disease (LEOPARD)
This project looks for genetic patterns that explain why some babies born before 28 weeks have lasting breathing problems, to help people born very prematurely.

What this research studies
If you or your child were born before 28 weeks, this work pulls together DNA and long-term health information from about 2,000 people who were born very early to look for groups ('endotypes') that share the same genetic pathways and later lung or heart-lung problems. The team uses existing genome-wide data and DNA samples from several newborn cohorts, including data collected through the ECHO program, plus medical records and follow-up exams at school age and beyond. By linking gene pathways to different clinical outcomes like bronchopulmonary dysplasia, asthma, or pulmonary vascular disease, researchers aim to define biologic subtypes that explain why outcomes vary. Those subtypes could guide future, more personalized prevention or treatment strategies for children born extremely preterm.
Who could benefit from this research
Good fit: Ideal participants are people (children or adults) who were born before 28 weeks gestation and who have DNA or genome-wide data and ongoing clinical follow-up in one of the contributing cohorts.
Not a fit: People born at term, those without a history of prematurity-related lung issues, or anyone seeking an immediate therapy are unlikely to get direct medical benefit from this research.
Why it matters
Potential benefit: If successful, this could help predict which babies born extremely preterm are at highest risk for chronic lung or heart-lung problems and point to better, more personalized prevention or treatments.
How similar studies have performed: Genetic and cohort studies have found some links to bronchopulmonary dysplasia but have been limited by size and heterogeneity, so combining large cohorts to define genetic endotypes is a relatively new and promising approach.
