What are the different types of congenital myopathy?

There are different types of congenital myopathies, some of which include:

  • Central core disease. This condition causes muscle weakness and developmental problems.
  • Centronuclear myopathies.
  • Congenital fiber type disproportion myopathy.
  • Nemaline myopathy.
  • Multiminicore disease.
  • Myotubular myopathy.
  • Other myopathies.

What is congenital myopathy?

Congenital myopathy refers to a group of muscle disorders that appear at birth or in infancy. Typically, an infant with a congenital myopathy will be “floppy,” have difficulty breathing or feeding, and will lag behind other babies in meeting normal developmental milestones such as turning over or sitting up.

Is congenital myopathy a form of muscular dystrophy?

Congenital myopathies are a broad range of disorders that result in hypotonia and weakness in the newborn period and early childhood. In contrast to congenital muscular dystrophy, weakness in patients with congenital myopathies is less progressive, the CK is usually normal, and no CNS involvement occurs.

What is fiber myopathy?

Collapse Section. Congenital fiber-type disproportion is a condition that primarily affects skeletal muscles, which are muscles used for movement. People with this condition typically experience muscle weakness (myopathy), particularly in the muscles of the shoulders, upper arms, hips, and thighs.

Is congenital myopathy progressive?

General symptoms of congenital myopathy in a newborn are the slow, progressive loss of muscle tone characterized by floppiness (hypotonia) and general weakness. Early motor skills and other critical developmental milestones may be delayed.

What is congenital muscular dystrophy?

Congenital muscular dystrophy (CMD) is a general term for a group of genetic muscle diseases that occur at birth (congenital) or early during infancy.

Is congenital myopathy a disability?

Adults with congenital myopathy should be encouraged to get adequate exercise and to avoid unhealthy dietary and sedentary habits that may lead to obesity. Affected adults may experience episodes of mild muscle weakness, but generally there are no major physical disabilities.

What is Nemaline myopathy?

Nemaline myopathy is defined by muscle weakness and the presence of fine, thread-like or rod-like structures called “nemaline bodies”, when muscle biopsies are viewed under the microscope.
