Frequently Asked Questions

Information About the DDX3X Registry

Who should I contact if I have any questions?

If you have any questions, please email

How much time will it take to participate?

The time to complete surveys will vary. We try to keep them as short and simple as possible. Each survey is expected to take between 10 to 20 minutes. Not all surveys need to be completed at the same time and progress can be saved.

How often should I visit the DFR to update my information?

We request that you visit the DFR every 3 months. This helps to ensure your contact and health information are current. You may also periodically receive emails requesting you to log in and answer some additional survey questions. Your ongoing participation helps ensure that DFR data remains responsive to current research needs.

What type of information will I receive by registering?

You may receive (1) general care guidelines and educational resources specific to DDX3X Syndrome; (2) information about meetings/conferences specific to DDX3X Syndrome; (3) notifications of clinical studies and trials; and (4) notifications about future natural history studies and DDX3X Centers of Excellence.

Will I be paid or compensated for my participation in the DFR?

There is no compensation for enrolling in the DFR, nor is there compensation for sharing your contact information to donate biospecimens.

The DFR may conduct raffles to provide small incentives to complete a particular survey. Up to every 3 months, the DFR may randomly select 1 to 2 participants who completed a specific survey to win a gift card.

What kinds of questions might the DFR help answer?

There are many questions that may be answered through the DFR. For example:

  1. What is the global population of individuals with DDX3X Syndrome?
  2. What is the natural history progression of DDX3X Syndrome?
  3. What are potential new pathways for treatments and cures?

How much data do I need to share, and how much is enough?

The more information you can contribute about your experience with DDX3X Syndrome, the better!

The DFR will continue to evolve as research advances. Additional surveys may be added and existing ones may change based on future need. Some will be shorter because only a few answers are needed; others will be more comprehensive, as needed, for research.

What kinds of information will I be asked to contribute?

You may be asked to contribute information about demographics including contact information, diagnostics, family history, symptoms, disease progression, medical history, and current treatments in surveys. You may also be asked to link and/or upload medical records, such as genetic testing reports, clinical notes, imaging, and/or testing reports. 

Why do I need to agree to an informed consent statement to participate in the DFR?

The DFR wants to make sure that you clearly understand how and why your health data is being requested. We also want you to be fully informed about the risks and benefits of participation. Documented informed consent will allow your data to be used in future research. 

Will the DFR share my data with researchers and doctors?

The DFR may share your data with researchers, doctors, or scientific laboratories who are researching DDX3X Syndrome. Interested parties are required to submit a written research proposal to The DDX3X Foundation. Before providing data to researchers, a Research Committee reviews the proposal to determine whether sharing data is in the best interest of the affected community.

What are the potential risks to participating in the DFR?

  • DFR participation and questionnaires – Information you choose to share on the DFR forums may allow another participant to identify you. Information shared by other participants in the forum may make you uncomfortable. Additionally, it is possible that reviewing health related events and completing surveys may cause emotional distress, embarrassment, or discomfort. These risks are anticipated to be minimal. You may decide to not complete a survey at any time.
  • Confidentiality of data, including personal information – There is a risk of loss of confidentiality. The security and privacy of your personal information and data is an important concern for us. Reasonable efforts will be made to protect you and your health information to the extent possible. The DDX3X Foundation and the company developing the DFR website and computer systems will take reasonable technical precautions to keep your data secure. Absolute confidentiality cannot be guaranteed.
  • Unforeseeable/unknown risks – There may be risks that are unknown at this time. You will be notified of any significant new findings that become known that may affect your willingness to continue in the study.

What are the potential benefits to registering and participating in the DFR?

Benefits to registering may include:

  • Participating in the community forum.

Why should I participate in the DFR?

We need your help to learn more about individuals with DDX3X Syndrome and provide researchers and therapeutic developers the data to pursue novel avenues toward a cure.

We believe you should register because:

  1. As a caretaker of a person living with DDX3X Syndrome, you know the disorder better than anyone. When you take surveys about your child's daily experiences and symptoms and share their medical records, you can help create a key resource for research. Every piece of data expands the information that researchers can draw from.
  2. Your voice matters in rare disease research! DDX3X Syndrome is rare so each person who chooses to participate can greatly expand the information available to researchers.
  3. It’s secure and easy to participate. Registration is simple and completed entirely online. With your informed consent to participate in research, you can contribute health data through surveys and by uploading medical records. The DFR is built to protect your identity and privacy.
  4. Your data can help bring us closer to a cure. The DFR data may help research and clinical trial progress more quickly and more efficiently. The data will be a powerful tool for clinical trials, treatments, and improved care.

Do I have a choice to register?

Participation in the DFR is completely voluntary. It is your choice to participate. You may also withdraw and stop participating for any reason and at any time.
