Presentation
Creatine kinase will be elevated. [2] Congenital Myopathies They may present at birth with marked weakness, hypotonia, external ophthalmoplegia and respiratory failure. [explainmedicine.com]
The disorder presents as progressive foot drop and hence has many differential diagnoses. [neurologyindia.com]
Early weakness of neck flexion is present in all patients. Mild involvement of the facial musculature (particularly of the orbicularis oculi and oris muscles) is often present. [orpha.net]
However, there are several uncommon presentations and findings noticed. [karger.com]

Extensive brain abnormalities are usually accompanied by severe mental retardation, epilepsy, visual loss and reduced life expectancy (about 11 to 16 years of age). [web.archive.org]
- Difficulty Climbing Stairs
Eventually, affected individuals may have difficulty climbing stairs or walking for an extended period of time. Some people with Miyoshi myopathy may eventually need wheelchair assistance. [ghr.nlm.nih.gov]
climbing stairs Difficulty walking up stairs 0003551 Difficulty running 0009046 Distal amyotrophy Distal muscle wasting 0003693 Distal muscle weakness Weakness of outermost muscles 0002460 Elevated serum creatine kinase Elevated blood creatine phosphokinase [rarediseases.info.nih.gov]
Later signs of weakness include difficulty in rising from a chair, difficulty climbing stairs and a wide gait with difficulty in balance. Q6. How is muscular dystrophy transmitted? A. [mda.org.au]
Proximal limb muscles are the earliest and most affected Difficulty climbing stairs, lifting arms overhead, and arising from chairs. [sites.google.com]
Respiratoric
- Respiratory Insufficiency
In some cases muscle weakness rapidly deteriorates, finally causing respiratory insufficiency or making the patient wheelchair bound (patient 3). [jnnp.bmj.com]
Respiratory insufficiency Advanced or severe weakness of the respiratory muscles (the diaphragm and rib cage muscles) may interfere with breathing. [web.archive.org]
Respiratory insufficiency is the most frequent cause of mortality from AMD. [neuroweb.us]
Hypotonia, floppy infant syndrome, respiratory insufficiency and reduced or absent deep tendon reflexes are common in early onset forms of MPP (i.e. the myopathic form of mitochondrial depletion syndrome typically due to TK2 mutations). [rarediseases.org]
The reason why different mutations cause different muscle pathologies is not clear, but clinical syndromes overlap with most patients having a rigid spine and respiratory insufficiency. [32] CFTD 4 The most common cause is due to autosomal dominant or [emedicine.medscape.com]

Since most of them manifest in infancy or early childhood they are less likely to be confused with GNE Myopathy. For details see: http://www.ninds.nih.gov/disorders/myopathy_congenital/myopathy_congenital.htm [gne-myopathy.org]

Learning that you or your child has a rare form of MD can be frightening and confusing. My parents wondered why I had this disease; we had no history of it in our family. [web.archive.org]
- Seizure
Medications used include steroids to slow muscle degeneration, anticonvulsants to control seizures and some muscle activity, and immunosuppressants to delay damage to dying muscle cells. [en.wikipedia.org]
Fukuyama congenital muscular dystrophy causes abnormalities in the brain and often seizures. Oculopharyngeal. Oculopharyngeal means eye and throat. This form of muscular dystrophy appears in men and women in their 40s, 50s, and 60s. [webmd.com]
People with this disorder have hypotonia and seizures. Severe mental retardation and multiple vision problems are encountered. The disorder is usually lethal in infancy. [web.archive.org]
In these cases, the muscle weakness is more severe and the child may have other problems such as fits (seizures), learning difficulties, breathing problems and a poorer outlook. [patient.info]

In contrast to HypoKPP, generalized flaccid paralysis is uncommon. People may get paresthesiae and achiness in the muscles prior to development of weakness. [sites.google.com]
Workup
To identify and minimize risk, a thorough preoperative workup is indispensable. [2], [3] If regional anesthesia is planned, a preoperative assessment of peripheral sensory nerve dysfunction should be considered. [ijaweb.org]
A neurologic examination that shows deficits in a single nerve or radicular distribution indicates a possible mononeuritis, entrapment neuropathy, or radiculopathy, and calls for a different workup than that required for a limb paresis in a patient with [aafp.org]

Treatment
Treatment of any specific problems, such as joint stiffness (contractures), heart or breathing problems. There is a lot of research into MD at present and new treatments may be available in the future. [patient.info]
Treatment - Distal myopathy Markesbery-Griggs type Specific treatment options may include physical and occupational therapy to improve muscle strength and, when necessary, the use of various devices including braces (e.g., ankle-foot orthosis) or wheelchairs [checkorphan.org]
Management and treatment No definitive treatments for MM exist and management is mainly supportive. [orpha.net]
In acquired myopathies, treatment is targeted toward the underlying cause. Treatment of statin myopathies is dependent on creatine phosphokinase levels and degree of muscle symptoms. Consider lower doses when initiating statin therapy. [clevelandclinicmeded.com]
Gene therapy, as a treatment, is in the early stages of study in humans. [en.wikipedia.org]

Etiology
Rhabdomyolysis may also be seen with infectious etiologies, alcohol, and toxic exposures. [clevelandclinicmeded.com]
Etiology It is caused by mutation of the MYH7 gene (14q11) that encodes the myosin heavy chain of type 1 fibers of skeletal muscle and cardiac ventricles (mutations have been identified in approximately 50% of individuals with MPD1). [orpha.net]
Epidemiology
