Brief Summary:
This study will follow participants who are screened and confirmed with a genetic diagnosis of Limb-girdle muscular dystrophy type 2E (LGMD2E/R4), Limb-girdle muscular dystrophy type 2D (LGMD2D/R3), or Limb-girdle muscular dystrophy type 2C (LGMD2C/R5). These enrolled participants will be followed to evaluate mobility and pulmonary function for up to 3 years after enrollment. Additional participant data will be collected from the time the individual began experiencing LGMD symptoms to the present.
