Trial summary

The study aims to find out if a specific blood molecule called miR-1, can be used as a biomarker to track the health of patients with certain muscle diseases. MicroRNAs (miRs) are small messengers that help control how cells grow and stay healthy. Read more about this study

About this study

The study aims to find out if a specific blood molecule called miR-1, can be used as a biomarker to track the health of patients with certain muscle diseases.

MicroRNAs (miRs) are small messengers that help control how cells grow and stay healthy. Some of these, like miR-1, are specifically found in muscles and the heart. Research shows that levels of miR-1 are often abnormal in people with muscle-wasting conditions, but more information are needed to understand how this relates to the severity of the disease.

The main goal is to compare the blood levels of miR-1 between four different groups at different ages and severities:

  1. Patients with Duchenne or Becker muscular dystrophy (DMD/DMB).
  2. Patients with Myotonic Dystrophy Type 1 (Steinert's disease).
  3. Patients with congenital myopathies.
  4. Healthy volunteers (control group). The main objective is to assess if miR-1 levels can accurately show how a muscular disease is progressing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. blood expression level of micro-RNA miR-1

    The main goal is to evaluate the interest of miR-1 as a blood biomarker for neuromuscular diseases, specifically muscular dystrophies and congenital myopathies.

    Measured: at a unique time of enrollment

Secondary outcomes (2)
  1. Demographic Correlations

    The study will analyze the correlation between blood expression levels of miR-1 and the age and sex of the participants

    Measured: at a unique time of enrollment

  2. Severity correlation

    the study will analyse the correlation between miR-1 levels and the clinical severity of the neuromuscular condition.

    Severity of Myotonic Dystrophy Type 1 (DM1): miR-1 level relation to the severity of the condition, looking at:

    • The clinical phenotype (based on the age of disease onset).
    • The number of CTG nucleotide repeats in the DMPK gene,.
    • The presence of cardiac involvement,.
    • Severity of Duchenne and Becker Muscular Dystrophies (DMD/DMB): miR-1 levels based on:
    • The presence of cardiac involvement,
    • The loss of ambulation (whether the patient has lost the ability to walk)

    Measured: at a unique time of enrollment
