What are congenital myopathies?
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.
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 are myopathies?
Myopathy is a general term referring to any disease that affects the muscles that control voluntary movement in the body. Patients experience muscle weakness due to a dysfunction of the muscle fibers. Some myopathies are genetic and can be passed from parent to child.
What are Myopathic symptoms?
The common symptoms of myopathy are muscle weakness, impaired function in activities of daily life, and, rarely, muscle pain and tenderness. Significant muscle pain and tenderness without weakness should prompt consideration of other causes.
What are structural myopathies?
A heterogeneous group of diseases characterized by the early onset of hypotonia, developmental delay of motor skills, non-progressive weakness. Each of these disorders is associated with a specific histologic muscle fiber abnormality.
What is the difference between myopathy and myositis?
Myopathies cause problems with the muscles you use for voluntary movements such as walking or trying to grab something. Patients often have muscle stiffness or weakness. Myositis: This is a type of myopathy that causes inflammation of your muscles, leading to weakness, swelling and pain.
What are the causes of myopathy?
Myopathy develops as the result of either inherited (congenital or genetic) disorders or acquired conditions of the muscles. Most commonly, people develop acquired myopathy from muscle fatigue, electrolyte imbalance, or dehydration, resulting in stiffness or cramping.
What types of myopathies are there?
Different Types of Myopathies
- Muscular Dystrophies. Muscular dystrophies are characterized by a lack of protein called dystrophin.
- Congenital Myopathy.
- Metabolic Myopathy.
- Mitochondrial Myopathy.
- Channelopathies.
- Myotonia Congenita.
- Inflammatory Myopathy.
- Endocrine Myopathy.
What causes mitochondrial myopathies?
Mitochondrial myopathies are caused by mutations, or changes, in genes — the cells’ blueprint for making proteins. They are inheritable, although they can occur with no family history, and they often affect members of the same family in different ways. For more, see Causes/Inheritance.

A heterogeneous group of diseases characterized by the early onset of hypotonia, developmental delay of motor skills, non-progressive weakness. Each of these disorders is associated with a specific histologic muscle fiber abnormality.
What is the life expectancy of congenital muscular dystrophy?
DMD affects about one in 5,000 males at birth. It is the most common type of muscular dystrophy. The average life expectancy is 26; however, with excellent care, some may live into their 30s or 40s.
What are rare types of congenital muscular dystrophy?
CMD with brain-eye , also called muscle-eye-brain disease, is a rare form of congenital muscular dystrophy (autosomal recessive disorder) causing a lack of normal muscle tone which can delay walking due to being weak, also paralysis of eye muscles and intellectual disability which affects an individuals way of processing information It is caused by a mutation in the POMGNT1 gene.
