Heart gene link explored in muscular dystrophy study
NCT ID NCT07515235
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to understand how different types of changes in the DMD gene are linked to heart problems in boys and young men with Duchenne or Becker muscular dystrophy. Researchers will use heart tests and blood samples to look for early signs of heart issues. The study involves 65 male participants aged 2 to 24. The goal is to improve early detection and care for heart complications in these conditions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Male sex * Age between 2 and 24 years at the time of enrollment * Genetically confirmed dystrophinopathy with a pathogenic or likely pathogenic variant in the DMD gene * Genetic confirmation based on at least one validated method, including MLPA, NGS, Sanger sequencing, array-CGH, or qPCR * Written informed consent from parents or legal guardians and, where applicable, consent from the participant Exclusion Criteria: * Absence of a genetically confirmed diagnosis of dystrophinopathy, including: * diagnosis based solely on muscle biopsy without molecular confirmation of a pathogenic or likely pathogenic DMD gene variant * absence of a confirmed pathogenic variant in the DMD gene, even if maternal carrier status has been identified, unless repeat genetic testing confirms a pathogenic variant in the participant * Presence of congenital heart disease or other genetic disorders causing primary cardiomyopathy * Presence of other neuromuscular disorders * Female carriers, including both manifesting and asymptomatic carriers * Comorbidities that may independently affect cardiac function, such as severe arterial hypertension, diabetes mellitus, or chronic kidney disease
