Additional Study Information: Each year more than 1,000 babies in the United States are born with a Congenital Diaphragmatic Hernia (CDH). For the majority of these babies, the cause of the CDH is unknown. The 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 healthcare providers and researchers across the country, coordinated at Columbia University Irving Medical Center. Multiple medical centers around the world 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.
