About Us

The DDX3X Foundation is a nonprofit organization founded in 2015 to find a cure for DDX3X syndrome. As part of our mission, the Foundation will support existing research, education, and treatment programs focused on DDX3X syndrome. The Foundation has three primary functions: research, connecting families, and raising awareness.

Formed by parents of DDX3X children, we understand the challenges associated with raising a child with a DDX3X syndrome. Many of the families affected by DDX3X went years without knowing the cause of their child’s delays. We exist to connect and support you.

Our Mission

Our mission is to connect families, resources, and the medical community to advance research for a cure to DDX3X syndrome. Our ultimate goal over the coming years is to accelerate brain function in individuals affected by DDX3X syndrome through advances in gene therapy and pharmaceuticals.
