The International Fragile X Premutation Registry is a HIPAA- and GDPR-compliant registry created to aid researchers in the Fragile X premutation field. The Registry is a tool, not a research project, and therefore the data is not publicly available.
If you are considering joining the Registry, here are five things you need to know:
- The project was created in partnership with an international advisory committee of dedicated Fragile X professionals from some of the world’s most respected institutions and patient advocacy organizations.
- No data is given to researchers or pharmaceutical companies. Data entered by registrants is only used to understand opportunities that are relevant to the registrant (e.g., sending FXPOI opportunities to only those females with FXPOI in the registry).
- Registrants are not directly contacted by researchers. Families are only sent IRB-approved materials after review and approval from the governance committee about the potential project. It is the registrant’s choice whether or not to contact the researcher.
- Registrants can request their data be removed from the Registry at any time. Please email Glenda M. Espinal for details.
- You can find more information about the design, implementation, and safety of the Registry below in the FAQ and in the consent form of the Registry when you enroll.
If you have more questions, we can help. Just email email@example.com or call (202) 747-6207.

About the Registry
Who Can Join
age & conditions
- Fragile X premutation carrier.
- Relative without a Fragile X premutation: If you are 18 years or older, related to someone affected by Fragile X and you do not have a Fragile X mutation, you are welcome to join the registry. If you choose to enroll in the registry, you will be considered a family member control. Examples of a family member control include spouses, in-laws, siblings, or a son or daughter.
Not sure if you’re a carrier?
Individuals who may or may not be carriers — as reflected by known inheritance patterns, e.g., parent is a carrier — can enroll and designate that they have not yet been tested.
What You’ll Need to Register
If you decide you’d like to participate, we’ll need:
- Your consent to participate.
- Your completed online form, which includes contact information, demographics, and some limited medical history.
The form includes two additional optional sections that ask more detailed demographic and health-related questions. You do not have to complete these sections to be enrolled in the registry.
What Happens Next
As a registrant, you are ultimately connected to a large international network of researchers and research teams studying the Fragile X premutation, and will be provided with yearly updates about research developments in the field.
Registrants may also be contacted by the registry team about research studies they may be eligible to participate in, including future treatment studies. (The NFXF will not have access to your private, personal information.)

Frequently Asked Questions
There are four categories of FAQs: About the Registry | Your Participation | Security | Enrolling
About the Registry
A registry is not considered research. A registry is a contact list that can be used to help support research.
Even though our registry is not considered research, we do ask that you provide consent to participate in the registry.
Clinicians, researchers, and family representatives from around the world have partnered with the NFXF to create an international premutation research registry.
Registrants are asked to provide contact, demographic, and basic medical information related to the premutation so they can be invited to participate in future research projects. Additional health questions may be asked, but are optional.
The purpose is to establish and maintain an online research participation registry for adults with the fragile X premutation and family members who do not have a fragile X mutation.
Premutation carriers who have been diagnosed with or have symptoms of FXTAS or FXPOI, as well as carriers without these problems are invited to participate.
A registry that includes a large and diverse group of individuals with the fragile X premutation (as well as family members without the premutation) will greatly facilitate research, including future treatment and intervention studies. Note that research is not restricted to medications, and includes any interventions that could positively impact your quality of life.
An advisory committee comprised of international fragile X professionals have come together to champion the International Fragile X Premutation Registry. Registry efforts are being led by David Hessl of the UC Davis MIND Institute and Robert Miller and Hilary Rosselot from NFXF.
The International Fragile X Premutation Registry is available internationally now! Initially launching in the U.S. only helped the team adjust the registry to be as helpful as possible, and provided the time needed to translate the registry into other languages. A Spanish-language translation will launch first, with others to follow throughout the coming year. All languages will be available on this page as they’re released.
If you’re interested in helping promote enrollment in your country, please reach out to Robert Miller at firstname.lastname@example.org.
We expect that you will be in this research registry for many years, perhaps decades, as it grows over time. You’ll receive at least yearly updates about the registry and developments in the field, as well as reminders to update your registry information.
Eventually, we expect thousands of people will enroll in the registry internationally.
If you have questions, concerns, complaints, or think the registry participation has hurt you, please contact one of the following:
- David Hessl, Registry Lead, UC Davis MIND Institute | email@example.com | (916) 703-0249
- Glenda M Espinal, UC Davis | HS-IFXPR@ucdavis.edu | (916) 703-0470
- Hilary Rosselot, National Fragile X Foundation | firstname.lastname@example.org | (202) 747-6207
- Robert Miller, National Fragile X Foundation | email@example.com | (202) 747-6207
Additionally, if you want to talk to someone besides the registry team, have questions about your rights as a registrant, want to get information or provide input about this registry, or you can’t reach the registry team, this registry plan has been reviewed by an institutional review board, and you may contact an IRB staff member at:
Phone: (916) 703-9151
Address: 2921 Stockton Blvd., Suite 1400, Room 1429, Sacramento, CA 95817
Please complete the IFXPR recruitment application. Once approved, the IFXPR team will share your IRB-approved materials with the registrants and they will contact you directly if they are interested in the research opportunity. You must have IRB approval for your project prior to requesting recruitment support from the registry.
Once you enroll in the registry, you will be contacted yearly by email or phone to update your information as it changes over time.
You may decide not to take part in the registry and it will not be held against you. You will still be eligible to participate in research studies, including treatment studies, however, it may be more difficult for researchers to contact you.
If you choose to enroll in the registry, you’ll be asked to enter information about yourself into a database, which is housed on a secure, HIPAA-compliant data system hosted by UC Davis (for more information, see the FAQs below under Security).
The information you’ll need to enter includes your name and contact information, the name and contact information of someone else who may be able to help the team locate you (e.g., if you move and we cannot find you), demographic information such as your race and ethnicity, details of your fragile X DNA test results (if available), and your interest in sharing biological samples (e.g., blood, saliva) in future research. You’ll also have the opportunity to provide details about any symptoms you may be experiencing.
The registry also asks for information such as your birth date, birth name, and where you were born. While it’s not required that you provide these details, if you do, the information will be used to create what is known as a GUID — Global Unique Identifier — for you.
A GUID is a universal participant ID allowing researchers to share data specific to a study participant and match participants across labs and research data repositories — without exposing personally identifiable information.
We want to emphasize that all personally identifying information (e.g., name, date of birth, address, email) is stored separately from the other data and is only accessible to the registry director and coordinator. It is not shared.
You can leave the registry at any time and it will not be held against you. If you decide to leave the registry and withdraw, you will no longer be notified of research opportunities through the registry.
If you decide to leave the registry, contact the team leader so that they can delete your information from the registry database. You may request to have all of your data deleted or only some of it.
The registry is not designed to benefit you directly. However, it is possible it may be helpful to you. For example, you may benefit from being informed about research progress and potential treatment studies that may be helpful to you in the future, or you may benefit from being informed and connected by the network of families and scientists concerned about people with the Fragile X premutation. You may experience satisfaction in contributing to the broader mission to improve the lives of and find effective treatments for people with the premutation. However, we cannot promise any direct benefits to you or others from your taking part in this registry.
The main risk for participating in this registry is that the information you provide could be mistakenly shared or stolen. This is a privacy risk. There are many safeguards in place to prevent this from happening, such as use of an encrypted database (where your information is scrambled), access limited only to the registry team, and ongoing staff training regarding data privacy and security. There may be other risks we do not know about. (For more information, see the FAQs below under Security.)
Yes! If you are a related to someone affected by Fragile X and you do not have a Fragile X mutation, you are welcome to join the registry. This invitation applies to you if you have a normal FMR1 test result or are presumed to have inherited a normal X chromosome.
If you choose to enroll in the registry, you will be considered a family member control. Examples of a family member control include spouses, in-laws, siblings, or a son or daughter age 18 or older. Your participation as family member control is extremely important, as researchers need individuals without the premutation as a comparison group to understand potential effects on health that are specific to the premutation.
No. The choice whether or not to participate in this project is completely voluntary and will not affect your medical care in any way.
Yes, the person in charge of the registry or the sponsor can remove you from the registry without your approval.
Possible reasons for removal include:
- You are not 18 years of age or older.
- You are not a member of a family affected by fragile X.
We will tell you about any new information that may affect your health, welfare, or choice to stay in the registry.
Once you are enrolled in the registry, researchers may wish to notify you of studies for which you may be able to participate. They will not be able to contact you directly. Rather, they will notify the registry team: an experienced committee of experts and Fragile X family representatives review the planned research and determine its appropriateness for registrant participation.
After approval the registry team sends you details about the study and you can decide whether to contact the researchers. The registry team may periodically update you by email or through social media about new or ongoing studies that may interest you.
The MIND Institute and NFXF are in charge of the International Fragile X Premutation Registry, which lives online in a secure database.

Stephanie Sherman, Ph.D., currently a Professor Emerita at Emory University, has been involved in research of fragile X-associated disorders for her entire career as a human geneticist.
Dr. Sherman’s early work helped to identify the unique aspects of the inheritance of fragile X syndrome prior to the discovery of the FMR1 gene. Since that time, she has been involved in understanding why the premutation increases the risk for ovarian dysfunction in women and for neurologic problems in both men and women. Her team aims to identify factors that trigger onset of symptoms in some but not all carriers. The ultimate goal is to identify perturbed biological pathways that have the potential to provide new insights into prevention and intervention.
Together with her colleagues, she has had the honor to work with hundreds of families who have been diagnosed with fragile X-associated disorders, and is grateful for this experience. Dr. Sherman has also had the opportunity to work closely with the National Fragile X Foundation’s efforts to promote research, care, and awareness.

Dr. Hudson is a molecular pharmacologist with expertise in cancer, natural products, molecular biology, and pharmacogenetics. He has integrated his research focus by identifying novel signature biomarkers with the evaluation of new chemopreventive cancer strategies, which have been evaluated in Phase I and Phase II clinical trials. His expertise in cancer-related processes, specifically mitochondrial health, which is critical in neurodegenerative diseases, has allowed him to transfer these skills to FXTAS. Currently, his lab assesses the biological activity of natural compounds on mitochondrial health in FXTAS. His research interests continue to expand in order to build collaborations across broad disciplines.
Dr. Hudson has served on the board of the Maryland Fragile X Resource group, which focuses on uniting families challenged with Fragile X. His personal experience with this syndrome and current research interest in FXTAS create a unique opportunity to assist with the development of the International Fragile X Premutation Registry.
