Finding Our Tribe Has Made All The Difference

The DDX3X Foundation was created by parents of children diagnosed with DDX3X Syndrome to support children like theirs, as well as adults, who have been diagnosed with this condition and the families that love them. As part of our mission, the Foundation supports existing research, education, and treatment programs focused on DDX3X Syndrome.

ABOUT DDX3X

What is DDX3X?

DDX3X Syndrome is often misdiagnosed as autism spectrum disorder, cerebral palsy, Rett Syndrome, Dandy-Walker Syndrome, or a generic developmentally delayed label. It is linked to intellectual disabilities, seizures, autism, low muscle tone, abnormalities of the brain, and slower physical developments. It presents in a broad spectrum—some individuals develop the ability to speak in full sentences, while others are nonverbal. Some individuals run, jump, and even ski, while others are unable to walk. 

A simple and comprehensive summary of DDX3X Syndrome is available in this document from RareChromo.org. For more information read the DDX3X Manuscript.

    Scarlett was diagnosed with DDX3X in October 2018. It was the final piece of our puzzle after six years of searching. Scarlett was small at birth and had noticeably low muscle tone. She was late on most of her milestones, but just barely, so she flew under the radar for a long time with her doctor.

  • Lucy Douglas

    Our sweet Lucy was diagnosed in October 2016 with DDX3X. The pregnancy and delivery of Lucy was completely normal, but we knew at a very young age that something was not quite right. Although a very happy and calm in nature, Lucy was a “floppy” baby who had severe reflux.

  • Virginia Frances

    Our sweet Virginia was born in March of 2005. After a completely normal pregnancy, she was breech, so the doctors flipped her and induced delivery. Virginia was very colicky from the start, and was late with all of her milestones.
