As with Duchenne, disease is almost always limited to males.** **Congenital** **birth** **Symptoms include general muscle weakness and possible joint deformities; disease progresses slowly; shortened life span.** **Duchenne** **2 to 6 years** **Symptoms include general muscle weakness and wasting; affects pelvis, upper arms, and upper legs; eventually involves all voluntary muscles; survival beyond 20s is rare. Seen in boys only. Very rarely can affect woman, who have much milder symptoms and a better prognosis.** **Distal** **40 to 60 years** **Symptoms include weakness and wasting of muscles of the hands, forearms, and lower legs; progression is slow; rarely leads to total incapacity.** **Emery-Dreifuss** **childhood to early teens** **Symptoms include weakness and wasting of shoulder, upper arm, and shin muscles; joint deformities are common; progression is slow; sudden death may occur from cardiac problems.** **Facioscapulohumeral** **childhood to early adults** **Symptoms include facial muscle weakness and weakness with some wasting of shoulders and upper arms; progression is slow with periods of rapid deterioration; life span may be many decades after onset.** **Limb-Girdle** **late childhood to middle age** **Symptoms include weakness and wasting, affecting shoulder girdle and pelvic girdle first; progression is slow; death is usually due to cardiopulmonary complications.** **Myotonic** **20 to 40 years** **Symptoms include weakness of all muscle groups accompanied by delayed relaxation of muscles after contraction; affects face, feet, hands, and neck first; progression is slow, sometimes spanning 50 to 60 years.** **Oculopharyngeal** **40 to 70 years** **Symptoms affect muscles of eyelids and throat causing weakening of throat muscles, which, in time, causes inability to swallow and emaciation from lack of food; progression is slow.** ---------------------------------- ------------------------------------ --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
