Other inherited muscular disorders include congenital myopathies (congenital myopathy) and familial periodic paralysis (familial periodic paralysis).
Muscular dystrophies are inherited progressive muscle disease, the result of a defect in one or more genes which are necessary for normal muscle structure and function. Duchenne muscular dystrophy is the most common and severe form of muscular dystrophy. The Becker muscular dystrophy begins, although it is very similar, later, showing a milder symptoms (Duchenne muscular dystrophy and Becker muscular dystrophy). Other forms are the Emery-Dreifuss Muscular Dystrophy, myotonic muscular dystrophy, the members-girdle muscular dystrophy, facioscapulohumeral muscular dystrophy which, oculopharyngeale muscular dystrophy and congenital muscular dystrophy (Other types of muscular dystrophy). Muscular dystrophies are distinguished by the selective distribution of muscle weakness and the specific cause of the genetic disorder. Other inherited muscular disorders include congenital myopathies (congenital myopathy) and familial periodic paralysis (familial periodic paralysis). Congenital metabolic diseases that affect the muscles, such as disorders of mitochondrial oxidative phosphorylation and glycogen storage diseases are discussed elsewhere (congenital metabolic disorders). In this chapter only those diseases are discussed, which mainly concern alone or muscles.
