Distal and myofibrillar myopathies are very rare conditions that cause muscles to get weaker over time. Because they’re so rare, doctors don’t always recognise them, and people can be given the wrong diagnosis or no diagnosis at all.
One reason for this is that we still don’t know much about these conditions. We don’t hold much information, so it’s hard to know how many people have them, how they change over time, why some people feel worse than others, or why they affect the heart and breathing muscles in some people but not in others.
This lack of knowledge makes it harder for people to get the right care and slows down the search for treatments. If scientists don’t know how the condition changes over time, they can’t tell if a treatment is helping.
To change this, scientists need to collect more information about symptoms, genetics, and what happens to muscles. This will help them understand the condition better and improve diagnosis, care and treatment in the future.
