Global study tracks rare muscle disease to pave way for future treatments
NCT ID NCT06374719
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows children and adults worldwide who have a rare genetic muscle disease called TNNT1 myopathy. Researchers aim to document how the disease progresses over time, including survival and motor milestones. The goal is to identify reliable measures that can be used in future clinical trials for potential therapies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Diagnosed with biallelic pathogenic variants of TNNT1 * Infantile-onset or childhood-onset proximal weakness without confounding medical conditions that could effect muscle health. Exclusion Criteria: * Another known or suspected medical condition (genetic or acquired) that could potentially alter the natural disease course or otherwise interfere with completion of study procedures.
