Natural History Evaluation of Charcot Marie Tooth Disease (CMT) Types CMT1B, CMT2A, CMT4A, CMT4C, and Others
This study aims to understand how different types of Charcot-Marie-Tooth disease (CMT) develop and progress over time. Researchers are particularly interested in CMT1B, CMT2A, CMT4A, and CMT4C. They will observe people with CMT to see how their symptoms change, and how their genetics are linked to these changes. The study also explores how well new tools, like the CMT Pediatric Scale and a basic set of measurements, can track the disease's effects over five years. This information is crucial because there are currently no effective treatments for CMT, and understanding its natural progression is vital for developing and testing future medicines.
Em resumo
Sobre o que é este estudo?
This study is like watching a film of how Charcot-Marie-Tooth disease (CMT) unfolds in people over several years. CMT is a group of inherited conditions that affect the nerves, leading to weakness and reduced feeling, mainly in the hands and feet. Researchers want to understand how different types of CMT, such as CMT1B, CMT2A, CMT4A, and CMT4C, naturally progress over time. This means they will carefully observe people with these conditions to see how their symptoms change and how their genetic make-up influences these changes. This kind of study, called an 'observational study,' is important because it helps scientists learn about the disease without giving any new treatments.
At the moment, there are no cures for CMT, and scientists don't fully understand how each type of the disease progresses. This lack of information makes it difficult to develop and test new medicines. By gathering detailed information on how the disease changes over five years, researchers hope to create a clearer picture of CMT's natural course. This will be invaluable for designing future clinical trials and finding effective treatments.
Another key goal of the study is to test new ways of measuring how CMT affects people. They're looking at a tool called the 'CMT Pediatric Scale' and a 'Minimal Dataset' to see if these can accurately track changes in symptoms and daily living over time. If these tools work well, they could be used in future research to reliably measure the impact of new treatments. The University of Iowa leads this international effort, working with several other hospitals and universities to bring together a large group of people with CMT for this important research.
Pontos principais
- This study observes how CMT changes over five years.
- It aims to understand different types of CMT (e.g., CMT1B, CMT2A).
- No new treatments are given; it's about learning the disease's natural course.
- Researchers are testing new ways to measure CMT's impact.
- Results will help design future clinical trials for new treatments.
- You'll need a confirmed CMT diagnosis or family link to join.
Quem pode ser elegível?
To join this study, you would need to be seen in person at one of the participating study centres for your first visit. The study is open to people of all ages who have Charcot-Marie-Tooth disease (CMT).
You would generally be eligible if you have had a genetic test that shows you have a particular gene change (called a 'variant') known to cause CMT. If you haven't had this specific test but a close family member (like a parent, child, or sibling) has a confirmed CMT-causing gene change, and you also show symptoms of CMT, you might also be able to join. There needs to be a clear link between your family member's gene change and your own condition.
Even if your genetic test results are a bit unclear, you might still be included if the study doctors believe your gene change is very likely causing your CMT, or if the genetic change has been found in several affected family members but not in unaffected ones. If you have CMT symptoms but don't know the exact type or gene change, the study might also be able to help figure that out.
Este estudo pode ser adequado para você?
Responda a estas perguntas rápidas para ver se você pode ser elegível. Este é apenas um guia — a decisão final é da equipe de pesquisa.
- Are you able to travel to a study centre for appointments?
- Have you been diagnosed with Charcot-Marie-Tooth disease (CMT)?
- Do you have a genetic test showing a CMT-causing gene change, or does a close family member with CMT?
- Do you understand this is an observational study, so no new medications will be provided?
- Are you able to commit to participating for five years?
O que envolve a participação?
If you decide to take part in this study, you won't be given any new medications or treatments as this is an observational study. This means the researchers will be watching and recording how your CMT progresses naturally over time. You would need to attend regular visits at one of the study centers over a period of five years. During these visits, the research team would carry out various assessments. These might include physical examinations to check your strength, sensation, and reflexes, and possibly nerve tests. They would also use special scales, like the CMT Pediatric Scale, to measure how your condition affects your daily life. The exact number and frequency of visits would be explained to you before you agree to participate.

Perguntas frequentes
What is Charcot-Marie-Tooth disease (CMT)?
CMT is a group of inherited conditions that affect the nerves, causing progressive weakness and loss of sensation, mainly in the feet, legs, hands, and arms.
Receberei algum novo tratamento neste estudo?
No, this is an 'observational' study, meaning researchers will only be observing how your condition progresses naturally. You won't be given any new treatments or medications.
Quanto tempo estarei no estudo?
If you join, you would be part of the study for five years, attending regular appointments at a study centre.
Quem está financiando esta pesquisa?
The study is supported by various organisations, including the National Institutes of Health (NIH) through its rare diseases programme, the Muscular Dystrophy Association (MDA), and the Charcot Marie Tooth Association (CMTA).
What are 'genotype-phenotype correlations'?
This means researchers are studying how specific genetic changes (genotype) are linked to the specific symptoms and progression (phenotype) that a person experiences with CMT.
