Characterization of DupEx2 Duchenne Muscular Dystrophy

Characterization of the Phenotypic Diversity in DupEx2 Duchenne Muscular Dystrophy and Identification of Predictive/Prognostic Markers

Observational IRCCS San Raffaele · NCT06337669

This study is trying to understand how Duchenne muscular dystrophy caused by a specific gene change affects movement, breathing, and heart health in patients, and whether it is less severe than the usual form of the disease.

What this trial studies

This study aims to characterize the clinical phenotype and potential predictive factors of patients with Duchenne muscular dystrophy (DMD) caused by duplication of exon 2. It will assess the progression of motor, respiratory, and cardiac functions, and investigate whether the Dup2 phenotype is milder than classic DMD. Whole genome sequencing will be performed to identify DNA breakpoints and correlate them with clinical outcomes. Additionally, the study will collect materials for future proteomic and transcriptomic analyses.

Who should consider this trial

Good fit: Ideal candidates for this study are pediatric and adult patients with genetically confirmed duplication of exon 2 in the dystrophin gene.

Not a fit: Patients without genetic confirmation of the Dup2 mutation will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding of Dup2 DMD, potentially guiding more effective, mutation-specific therapies.

How similar studies have performed: While studies on DMD have been conducted, this specific focus on Dup2 and its unique characteristics is relatively novel.
