Brief Summary:
This is the 2 years extension of the prospective and longitudinal study of the natural history and functional status of patients with myotubular myopathy and other centronuclear (CNM) sponsored by Dynacure including ten additional pediatric patients with mutation in MTM1 or DNM2 genes). the patients are planned to be enrolled in one year leading to an expected total number of 70 patients followed at least over 1 year period. Data from the study will be used to characterize the disease course of CNM and determine which outcome measures will be the best to assess the efficacy of potential therapies.

Actual Primary Completion Date : September 30, 2021
Actual Study Completion Date : September 30, 2021



Intervention Details:
  • Other: Standardized strength, respiratory and motor function assessments
    Standardized assessments will be adjusted by the age, the ambulant status and the respiratory status of the patient. The visit frequency will also be adjusted according to the age and to the time spent in the study varying between quarterly to yearly.


Primary Outcome Measures :
  1. MFM score change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
    Motor Function Measure scale. The total test score can range from 0 if the subject cannot perform any of the items to 100 if all the items are fully achieved.

  2. CHOP-INTEND score change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
    Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders

  3. Modified Hammersmith score change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
    Modified Hammersmith Functional Motor Scale. The total test score can range from 0 if the subject cannot perform any of the items to 40 if all the items are fully achieved

  4. Moviplate score change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
    Moviplate score

  5. 6MWD change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
    6 Minute Walking Distance

  6. Grip strength change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
    MyoGrip

  7. Pinch strength change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
    MyoPinch

  8. Forced Vital Capacity change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
  9. Peak Cough Flow change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
  10. Maximum Inspiratory Pressure change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
  11. Maximum Expiratory Pressure change from baseline [ Time Frame: Baseline, 6 months, 12 months and every year up to 60 months ]
