The National Fragile X Foundation is closing the doors to our brick and mortar office, and our new mailing address will be located in Washington, DC. So please, update your address books!

The biggest reason for this change is to allow us to divert more of your generous donations to serve the Fragile X community by saving on rental space and equipment.

Rest assured that we are still the same organization that you know and support. The only big difference is that the work is being done from home offices instead of an office building. Many of our team members have already been doing this for years! I’m sure that most of you won’t even notice the change.

Please update your address books with our new mailing address:

National Fragile X Foundation
2100 M St., NW
Ste.170 Box 302
Washington, DC 20037-1233


Thank you for continuing to support us as we bravely push forward into the future.

NFXF Chief Executive Officer
