Lot Snijders Blok has written a proposal for a DDX3X GeneReviews listing, together with Tjitske Kleefstra and the group of Elliot Sherr in the USA.
It’s currently being edited by the GeneReviews people, and they hope to have it online in the coming months. GeneReviews is used a lot by clinicians around the world to understand rare diseases better, and to get more consistent in terms of management/genetic counselling/etc. Hopefully this will help for the management and counselling of all the DDX3X (new and old) families as well!
