Limb-girdle myasthenia, nonfamilial – http://id.who.int/icd/entity/697826513

Limb-girdle myasthenias are rare conditions in which impaired neuromuscular transmission leads to weakness of proximal limb muscles with little or no involvement of the ocular, bulbar or facial muscles, giving rise to a characteristic “waddling” gait. In most of these patients the onset of muscle weakness is first noticed in infancy or childhood, but a later onset is described. Nonfamilial limb-girdle myasthenia include autoimmune forms.
