POGLUT1-related limb-girdle muscular dystrophy R21

A rare autosomal recessive limb-girdle muscular dystrophy characterized by adult onset of progressive muscle weakness and atrophy in the proximal upper and lower limbs, leading to scapular winging and loss of independent ambulation. Respiratory function may become impaired in the course of the disease. Fatty degeneration of internal regions of thigh muscles sparing external areas has been reported, as well as a reduction of alpha-dystroglycan in muscle biopsies.
