About this trial

The goal of this observational study is to investigate whether the type, location, and extent of pathogenic variants in the DMD gene are associated with cardiac dysfunction in male children, adolescents, and young adults with dystrophinopathies. The study also evaluates whether cardiac biomarkers and electrocardiographic findings can facilitate the early identification of cardiac involvement. Participants will undergo electrocardiography, blood sampling for cardiac biomarker assessment, and transthoracic echocardiography, with cardiac dysfunction evaluated using ejection fraction (EF) and global longitudinal strain (GLS).

Eligibility criteria

Qualifiers

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

Disqualifiers

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
