Facioscapulohumeral muscular dystrophy (FSHD) typically presents with weakness of the facial muscles, the stabilizers of the scapula, or the dorsiflexors of the foot. Severity is highly variable. Weakness is slowly progressive and approximately 20% of affected individuals eventually require a wheelchair. Life expectancy is not shortened. [from GeneReviews]

Facioscapulohumeral muscular dystrophy (FSHD) is a skeletal muscle disorder characterized by adult onset of progressive muscle weakness of the face and upper extremity muscles. With disease progression, other muscles also may become affected. There is significant clinical variability and incomplete penetrance (summary by van den Boogaard et al., 2016). For a discussion of genetic heterogeneity of FSHD, see FSHD1 (158900). [from OMIM]

Facioscapulohumeral muscular dystrophy-3 (FSHD3) is a digenic muscle disorder characterized by adult onset of proximal muscle weakness affecting the face, neck, scapular muscles, and upper and lower limbs. Muscle involvement is usually asymmetric, and other muscle groups may become involved with progression of the disease (summary by Hamanaka et al., 2020). For a discussion of genetic heterogeneity of FSHD, see FSHD1 (158900). [from OMIM]
