  Distal myopathy (generic term)   (Site not responding. Last check: 2007-10-30)
Distal myopathies are a heterogeneous group of genetic disorders characterized clinically by progressive muscular weakness of upper and lower limbs (hands or feet).
Nonaka myopathy and Miyoshi myopathy are transmitted in an autosomal dominant pattern, whereas Welander myopathy, Udd/Markesbery-Griggs myopathy, distal myopathy with vocal cord and pharyngeal weakness and Laing myopathy are inherited as autosomal recessive traits.
Miyoshi myopathy is associated with a striking elevated serum creatine kinase level and the typical findings of muscular dystrophy, whereas most of the distal myopathies have normal or mildly elevated creatine kinase levels and share the common pathologic feature of rimmed vacuoles.

 Distal myopathy, Nonaka type
This clinically distinct myopathy is a mid-life onset distal myopathy characterised by tibialis anterior weakness and progressive respiratory muscle involvement present from the onset of the disease.
It is a distal myopathy with late onset (after the age of 40) inherited as an autosomal dominant trait.
Although this region overlaps with that involved in Miyoshi myopathy and limb-girdle muscular dystrophy 2B, which are both due to mutations in the dysferlin gene, this gene is not responsible for Welander distal myopathy.

 eMedicine - Congenital Myopathies : Article by Glenn Lopate, MD
Rare congenital myopathies: In the most recent edition of the textbook Myology (2004), the remaining congenital myopathies are divided into “probable,” meaning several familial cases have been reported, and “possible or doubtful,” meaning fewer than 10 cases have been reported.
Myopathy with muscle spindle excess: Only 1 case has been described and was characterized by congenital onset, hypotonia, proximal weakness, and arthrogryposis.
Because the diagnosis of congenital myopathy is often difficult, a clinician experienced in the diagnosis and treatment of neuromuscular diseases should interpret the findings of laboratory tests (ie, CK level), electrodiagnostic studies, and muscle biopsies.

 More on Myopathy
In medicine, a myopathy is a neuromuscular disease in which the muscle fibers dysfunction for any one of many reasons, resulting in muscular weakness.
Because myopathy is such a general term, there are several classes of myopathy.
Because different types of myopathies are caused by many different pathways, there is no single treatment for myopathy.
