People with early onset facioscapulohumeral muscular dystrophy have more severe disease

Takeaway

  • People with early-onset facioscapulohumeral muscular dystrophy (FSHD) have disease severity that is greater than in people with classic-onset FSHD.

Why this matters

  • The finding of early disease onset as a prognostic factor for severity would facilitate patient counselling and clinical management.
