	Myopathy - Wikipedia, the free encyclopedia
		In medicine, a myopathy is a neuromuscular disease in which the muscle fibers dysfunction for any one of many reasons, resulting in muscular weakness.
		A less severe form of centronuclear myopathy that may present itself at birth or in early childhood progresses slowly and is inherited as an autosomal recessive genetic trait.
		The least severe of the three forms of centronuclear myopathy first appears during the second and third decades of life and is slowly progressive; it is inherited as an autosomal dominant genetic trait.

	Nemaline myopathy - Wikipedia, the free encyclopedia
		Nemaline myopathy (also called rod myopathy or nemaline rod myopathy) is a group of congenital, hereditary neuromuscular disorders that cause muscle weakness, generally nonprogressive, of varying severity.
		"Myopathy" means "muscle disease," and a biopsy of muscle from a person with nemaline myopathy shows abnormal thread-like rods, called nemaline bodies, in the muscle cells.
		Genetic mutations found to be responsible for the disorder include the alpha-actin gene, the nebulin gene, tropomyosin 2 gene, tropomyosin 3 gene, and troponin T. The physical capabilities of a given person with NM do not correlate well either with genotype or with muscle pathology as observed in the biopsy.

	Myopathy - Pharmpedia
		The myopathies are neuromuscular disorders in which the primary symptom is muscle weakness due to dysfunction of muscle fiber.
		Myopathies can be inherited (such as the muscular dystrophies) or acquired (such as common muscle cramps).

	Myotubular Myopathy- Health Encyclopedia and Reference
		Myotubular myopathy is a congenital polymyopathy - a disease some people are born with that affects multiple muscles in the body.
		The disease is also called centronuclear myopathy because the nuclei of affected muscle cells are found in the center of the cell instead of at the periphery as is true with healthy muscle cells.
		Common symptoms of myotubular myopathy are drooping of the upper eyelids, facial weakness and foot drop, flout spells, as well as some weakness of the limbs and trunk.

		Nemaline rod myopathy is a dominantly or recessively inherited, genetic disease characterized by infantile muscle weakness and loss of muscle tone, accompanied by problems in suckling or feeding, delay in walking, and occasionally respiratory problems.
		Centronuclear (myotubular) myopathy is an inherited genetic disorder characterized by muscle weakness and loss of tone present at birth or by development of muscle weakness later in infancy.
		Patients with nemaline rod myopathy may have a normal life expectancy with progressive weakness, or may die early in infancy from respiratory distress depending upon the severity of the disorder.

	Hollow Visceral Myopathy in a 5-year old Boy: a Case Report (Site not responding. Last check: 2007-11-01)
		Hollow visceral myopathy is a rare clinical entity characterized by impaired intestinal function in the absence of mechanical occlusion.
		Hollow visceral myopathy is a rare clinical entity characterized by impaired intestinal function and motility in the absence of mechanical occlusion.1 It is considered a form of chronic intestinal psuedo-obstruction.2 Intestinal psuedo-obstruction encompasses a broad range of disorders and is classified as primary (idiopathic) or secondary when it is due to an underlying disorder.
		Prognosis for hollow visceral myopathy is poorer in the neonatal period than in childhood or adulthood.7 Gastrointestinal involvement seems to be the limiting factor in prognosis of such children as parentral nutrition with its associated complications may be required from early neonatal period.

		Nemaline myopathy (NM) is a rare neuromuscular disease that is associated with a broad range of special medical needs, such as weakness of the respiratory muscles and those in the face, arms, legs and the trunk as well as low muscle tone.
		Nemaline myopathy may be passed on from parents to children in some families, while in others, it may arise for the first time, with no previous family history of the disorder.
		If you are the parent of a child with nemaline myopathy, if you yourself are affected, or if you are the healthcare provider of a patient with nemaline myopathy, you may be able to help us find new genes and proteins associated with nemaline myopathy.

		Myopathy with substantial increase in centrally located nuclei as their salient features was first recognized in 1966 in a 12-year-old boy with weakness, including involvement of facial and extraocular muscles, and delayed motor development
		The term “centronuclear myopathy” was introduced to describe the disease in two teenage sisters who had weakness, including involvement of the extraocular muscles, and impaired motor development
		Although X-linked myotubular myopathy shares the feature of centrally located nuclei with centronuclear myopathy, X-linked myotubular myopathy is related to the MTM1 gene on chromosome Xq28 which codes for the myotubularin protein.

		When myotubular myopathy is inherited in an autosomal recessive fashion, onset is not neonatal, but usually earlier than that of the autosomal dominant form.
		Since there are patients with myotubular myopathy with no detectable gene change, it is the purpose of our study to determine what other genes are responsible for the cause of myotubular myopathy, how they can arise and how they are inherited.
		If you are the parent of a child with myotubular myopathy, if you yourself are affected, or if you are a healthcare provider of a patient with myotubular myopathy, you may be able to help us to develop better therapies and treatments for this disorder.

		At the end of investigations, diagnosis of a metabolic myopathy was made in 33 patients: glycogenolysis or glycolysis deficiency in 8 cases, mitochondrial myopathy in 24 cases and CPT II deficiency in one case.
		However, its sensitivity was lower for the detection of mitochondrial myopathies, as is also known for the other in vivo metabolic investigations, reflecting the heterogeneity of expression of mitochondrial abnormalities in a given muscle.
		Other muscle diseases, muscular dystrophies or myopathies, were detected in 18% of these patients, emphasizing the value of clinical and histopathological examination of patients with previous rhabdomyolysis.

	MYOTUBULAR MYOPATHY: Contact a Family - for families with disabled children: information on rare syndromes and disorders
		Myotubular Myopathy is a congenital myopathy, one of a group of conditions causing weakness and wasting of the muscles with symptoms usually present at birth.
		Myotubular Myopathy is so called because the affected muscle fibres look like myotubes (muscle cells found only during fetal development when the fetus is between twelve to twenty weeks old).
		The condition is also known as 'centronuclear myopathy' because the nuclei of affected muscle cells are found in the centre of each cell instead of the periphery (as occurs in healthy muscle cells).
