Find a Study on Congenital Anomalies

Select one of the following links to get ClinicalTrials.gov search results for studies on congenital anomalies:

NICHD is using the term “congenital anomalies” to describe conditions that were once called “birth defects” because the latter carries negative undertones and does not reflect the many abilities and talents of those affected by these differences. However, as communities are still discussing alternative terms for describing these conditions, NICHD will also continue to use the term “birth defects” in clinical trial searches until a consensus is reached.
