We are currently enrolling children born in North Carolina.
RTI International and the University of North Carolina at Chapel Hill are conducting a research study to learn more about early development of young children with Fragile X in North Carolina, and the experiences of their parents when obtaining the diagnosis and early intervention services.
This research study is currently seeking male and female children that have a premutation or full mutation Fragile X (including mosaic) and meet the following criteria:
- Age 0–5.
- Born in North Carolina.
- Lived in North Carolina between the ages of 0 and 3 years.
- Live in a home where English is the primary language spoken.
What to Expect
Research study activities for qualified children and their parents include:
- Home Visits: Depending on the child’s age, there will be 1–3 home visits (developmental assessments) with you and your child, each taking 2–3 hours:
- At enrollment
- Age 3
- Age 5
- Summary Reports: After each visit, you will receive a brief summary report about your child’s development plus a $50 gift card for your time.
- Questionnaires: Parents will be asked to complete some questionnaires (approx. 1–2 hours).
The following is a list of some of the assessments and questionnaires that will be included in the study:
- Bayley-3/SB-5 (50 mins)
- PDMS-2 (30–45 mins)
- AOSI (up to 18 months) 20 mins/ADOS (45–60 mins)
Parent Report Questionnaires: Questionnaires will be sent ahead of time so that parents have plenty of time to complete.
- Vineland Adaptive Behavior Scales, Third Edition (20 mins)
- Sensory Profile, Second Edition (10–20 mins)
- Rothbart Temperament Very Short Forms (10 mins)
- Medical Outcomes Study-Social Support Survey (5 mins)
- Feeding Flock Assessment. (1–2 surveys, 10–20 mins)
- Sleep Questionnaire (5 mins)
- Family Demographics including FX status (5 mins, 1st visit only)
- Behavior Rating Inventory of Executive Function (BRIEF) (15 mins)
- State-Trait Anxiety Inventory (10 mins)

Our Most Recent Opportunities
RTI International and the University of North Carolina at Chapel Hill are conducting an early intervention study to learn about the best ways to support early development in infants identified with the full mutation of Fragile X. Babies 0–9 months old with the full mutation, and their caregivers, may be eligible to participate.
Doctors at Rush University are researching cognition, balance, and walking patterns in people who carry a premutation in the Fragile X (FMR1) gene.
The University of South Carolina is conducting a research study focusing on the range of language, social, and cognitive features that may be associated with variations on the FMR1 gene. Women age 35-75 who are carriers of the Fragile X premutation may be eligible to participate.
An Alliant International University clinical psychology doctoral candidate is conducting a research study to learn about the cognitive profile of children with a full mutation of Fragile X. Males and transgender females between the age of 8 and 12 may be eligible to participate.
The MIND Group at the University of Minnesota is conducting a survey for parents of children with Fragile X syndrome to learn about how genetic and neurodevelopmental differences impact behavioral strengths and challenges. Parents of 3–17 year old children living with Fragile X are eligible to participate.
