General information

Background and purpose

For the treatment of Myotonic Dystrophy type 1 and type 2/PROMM, promising new therapeutic strategies are currently being developed which need to be tested in clinical trials/research studies. This international registry will make the recruitment of Myotonic Dystrophy patients for trials or studies easier by helping to identify suitable patients for particular trials or studies and by enabling them to be contacted and informed quickly when there is a trial or study they might be interested in. More information

Target group

This registry is for patients affected by Myotonic Dystrophy type 1 (DM1, Curschmann-Steinert) or Myotonic Dystrophy type 2 (DM2, PROMM). TREAT-NMD has already launched several other registries that are collecting data to prepare for trial readiness, such as the global registries for patients with Duchenne Muscular Dystrophy and Spinal Muscular Atrophy. Similar as with these other registries, this registry is primarily designed to register patients who might be suitable for participation in future clinical trials of new therapies, and to help the researchers find the best way of caring for patients with DM1 or DM2. Therefore, this registry is intended for patients currently living with the condition and not as a record for those who have already died.

Advantages for patients

If you are a patient affected by DM1 or DM2 and register here, we can direct you to clinical trials and research results (such as new treatments) that might be of specific interest to you. In addition, by registering you are helping researchers obtain precise data about the prevalence of Myotonic Dystrophies (DM1 and DM2), which could be of benefit to all affected patients. .

Required data

The required data will be asked for in a two-part questionnaire.

  • Part 1: This part is to be completed by the patient or carer / guardian / parent of the patient. You can view all the questions in advance.
  • Part 2: This part is to be completed by a professional involved, for example by a geneticist or a neurologist /neuromuscular specialist. The information required is related to test results which would not necessarily be readily available to the patient, such as test results related to their respiratory function, cardiac status, mutation analysis and outcome scores.


Registration process

Patients can register on their own online by clicking “Registration”, which leads them to the web application for the DM patient registry. This registry is a self-report registry, which means that patients initiate the registration by themselves.

In order to register, you should first read the patient information and agree to register by consenting online. Then you register by entering your personal and contact details. In the next steps you and your doctor fill in the online questionnaire. In this questionnaire, questions are related to your myotonic dystrophy condition.

If necessary, you can save and interrupt your registration at any time, for instance in order to consult a doctor to discuss questions. More information on the exact registration process.

Data access

Staff in charge of the registry have access to your data and can contact you if you might be suitable for a particular study. Furthermore, the doctor – who you choose and authorise in the form yourself – will fill in the second part of the questionnaire, and will be able to view (but not edit) the first part of the questionnaire.

Data updates

To make sure that the data in the registry are correct and valuable, it is essential that we update them regularly. To do this, we will send you emails once a year asking you to tell us about any changes in your medical condition. You can easily update your data yourself at any time by logging into the registry with your username and password and changing your data. If there are any major changes in your medical or contact details that occur in the period between the annual updates, please also notify us or update your data yourself. Such changes could be for example a change of address or the loss of ambulation.

Data protection

Your data are stored on a specially secured computer in University of Munich hospital, which can be accessed only by selected people. Information that you enter online via the Internet is encrypted while being transferred, so that it cannot be intercepted. More information about data protection


Here you will find answers to some questions that you might have when using the registry.

I had to temporarily interrupt my registration. When I wanted to continue, I had to type in my password. Why?

For security reasons you are logged out automatically if you have been idle for two hours, i.e. not clicked on a link or button or typed in any text. After you type in your password as requested, in most cases you should be back on the page you were on before you were logged out. If not, you can click through to the desired page via the navigation bar on the left. If at the time you were automatically logged out you had made changes in a form without clicking the “Save” button, you will have to make these changes again.

I have forgotten my password. What should I do?

If you forget your password, please follow the instructions on the “Forgot password” page.

I have forgotten my username. What should I do?

You can find your username on the list of backup passwords you should have received by mail after registration. Please also see the page “Forgot password”.
