Informations about the disease

Clinical Comment

Skeletal + cardiac muscle disorders with disintegration of sarcomeric Z disc + myofibrils; aggregation of degradation products into intracellular inclusions, typically clinically with slowly-progressive weakness of distal muscles, highly variable, can affect proximal muscles, cardiac + respiratory muscles

DD: Myotonic dystrophy 1 + 2 (repeat expansions in DMPK + CNBP genes), Inclusion body myopathy type 2 (GNE gene), Inclusion body myositis, Dysferlinopathy (DYSF gene), Motor and sensory neuropathies, other muscular dystrophies predominantly affecting distal muscles, tibial muscular dystrophy (Udd distal myopathy; TTN gene), telethoninopathy, Laing distal myopathy (MYH7 gene), Welander's distal dystrophy (TIA1 gene), facioscapulohumeral dystrophy (D4Z4 macrosatellite repeat contraction), anoctamin-5 related muscular dystrophy, and other sporadically occurring or dominantly inherited muscular dystrophies.
