Hello and welcome to the Gene DDX3X Facebook community. If your child was just diagnosed, we all understand it can be a very scary and overwhelming experience. You will find a lot of support and information here and in our Facebook group.
RECENTLY DIAGNOSED WITH DDX3X? page (https://ddx3x.org/recently-diagnosed-ddx3x/) provides some of the key information to get you started but there is a lot more to learn in the Facebook group’s timeline. If you are interested in something specific do a quick search in the timeline first, post your question if you don’t find what you are looking for.
A simple and comprehensive summary of DDX3X is available in this document from RareChromo.org.
For more information read DDX3x manuscript (The American Journal of Human Genetics 97, 1–10, August 6, 2015): Mutations in DDX3X Are a Common Cause of Unexplained Intellectual Disability with Gender-Specific Effects on Wnt Signaling.
