Brief Summary:
Prospective, longitudinal, interventional, single-group, multicenter natural history study to better know the LGMD2I disease physiopathology. The duration of participation for each patient will be up to 24 months.

Condition or disease

Detailed Description:

Study duration Duration from First visit of first patient (FPFV) to Last visit of last patient (LPLV) : 3 years

Study objectives Primary objective:

To characterize the disease course in Limb-Girdle Muscular Dystrophy 2I (LGMD2I) patients using standardized and disease appropriate evaluations.

Secondary objectives:

To identify clinical, imaging and/or laboratory parameters that are indicators of the disease course in LGMD2I To identify the best outcome measure for further therapeutics approaches
