The CDH Study

What Is The DHREAMS Study?

DHREAMS (Diaphragmatic Hernia Research & Exploration; Advancing Molecular Science) study was created to improve the understanding of the molecular genetic basis of CDH.  This National Institute of Health (NIH)-funded research team is composed of health care providers and researchers across the country, coordinated at Columbia University Medical Center. Multiple medical centers are enrolling individuals and families with CDH.  The knowledge gained through this research will lead to improved diagnosis, treatment, and quality of life for individuals and families with CDH.

What is CDH?

A congenital diaphragmatic hernia (CDH) occurs when the diaphragm does not form properly. The diaphragm is a thin sheet of muscle that separates the abdomen from the chest. The diaphragm is an important muscle for breathing. Currently, little is known about why this birth defect occurs.
