Our Fragile X World collects data from families using online surveys and in-person studies. The studies cover topics such as sensory or behavioral challenges, health care experiences, and the impact of fragile X on families.

Taking part in a study is one way you and your family can help support our work. That is why we created the Our Fragile X World registry. This registry is how we let families know when they can take part in a study.

We are currently enrolling parents of children with the full mutation or the premutation to participate in one or both of the following new studies! We want to learn more about the early development of children with fragile X and their family’s experiences with getting the diagnosis and early intervention. Information from these studies will help support parents of infants who have been newly diagnosed with fragile X through our Early Check study in North Carolina.

Survey: Early Experiences with Fragile X

This national survey is for parents of children 13 and under with the premutation or full mutation of fragile X, who live in the US.

  • If the first child diagnosed in your family (full or premutation) is 13 years or younger, OR, if any of your children with the full or premutation are 7 or younger, you are invited to take the survey!

If you are in our registry and eligible for this survey, we have emailed you a survey access code. Please check your email. You will need to enter this code before you start the survey.

Preferences for the Use of Medical Records in Research Survey

We conducted two surveys, one with parents of individuals with fragile X syndrome and another with young adults with fragile X syndrome, to explore what factors are important to when deciding whether to allow researchers to access their (or their child’s) electronic health record.

Fragile X Caregiver Burden Survey (2011)

In this survey, we talked to caregivers of people with fragile X. We asked them how caregiving affected their health, finances, and daily lives. We also looked at the health characteristics of children and adults with fragile X syndrome. We asked caregivers about the number of visits their child made to specialists and their child's use of medications.

National Fragile X Survey – Phase I (2008)

In 2007, we led the first national survey of families touched by fragile X syndrome. Over 1,250 families took part in the study. They answered questions about topics such as family adaptation, conditions related to fragile X syndrome, health experiences, and functional skills. This survey provided new knowledge about fragile X syndrome. It showed that parents are a valuable source of research information.
