You can sign up for our registry if you or a family member has
fragile X, including the premutation or full mutation of fragile X syndrome (FXS).

You can sign up if

You or your spouse has the fragile X premutation or FXS.
You are a family member (such as a grandparent) who has legal custody of a child
with the fragile X premutation or FXS.
You are the parent of a child with the fragile X premutation or FXS
under 18 years of age (this includes biological, step, adoptive, and foster parents)
or the parent of an adult male with FXS 18 years or older.
You are the legal guardian of an adult family member, including a sibling, child,
or other relative, with the fragile X premutation or FXS.

Our registry has contact information for people with fragile X and their families.

We keep information of only those people who have agreed to be on our list by taking our enrollment survey. All of our studies are approved by an ethics board. All of your responses will be private, confidential, and secure. Have more questions about Our Fragile X World? Please contact us.
