What are the different types of myopathy?

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.

Can myopathy be inherited?

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 myopathies?

Myopathy is a disorder of the skeletal muscles. Muscle disorders arise from abnormalities that affect the muscle’s structure or metabolism, and have a variety of causes. Some are inherited while others are acquired.

What is genetic myopathy?

Introduction. Hereditary myopathies are a heterogeneous group of inherited diseases primarily affecting the skeletal muscle tissue. These are caused by mutations in genes encoding proteins critical for muscle structure and function, with X-linked, autosomal-recessive or -dominant inheritance pattern.

Is myopathy the same as muscular dystrophy?

Muscular dystrophy refers to a group of more than 30 inherited (genetic) diseases that cause muscle weakness. These conditions are a type of myopathy, a disease of the skeletal muscles. Over time, muscles shrink and become weaker, affecting your ability to walk and perform daily activities like brushing your teeth.

What are the signs of myopathy?

What are the symptoms of myopathy?

  • Muscle weakness, most commonly of your upper arms and shoulders and thighs (more common and more severe).
  • Muscle cramps, stiffness and spasms.
  • Fatigue with exertion.
  • Lack of energy.

What are congenital myopathies?

Congenital myopathy (CM) is an extremely rare, inherited disease that affects the muscles (myopathy) and is characterized by the lack of muscle tone or floppiness at birth. There are several different subtypes of congenital myopathy and many are caused by changes (mutations) in specific genes.

What causes myopathy disease?

The primary symptom of myopathy is muscle weakness. Myopathies can be caused by genetic defects or endocrine or metabolic disorders. Other causes are infection, muscle injury, medication, problems with electrolyte levels and thyroid disease.

What causes myopathy?

What are hereditary Inclusion body myopathies?

Hereditary inclusion body myopathies ( HIBM) are a group of rare genetic disorders which have different symptoms. Generally, they are neuromuscular disorders characterized by muscle weakness developing in young adults.

What is the classification of body myopathy?

Classification. Types of hereditary inclusion body myopathy: IBM2 is the most common form, and is an autosomal recessive form, caused by mutations in the GNE gene; this form mainly affects leg muscles, but with an unusual distribution that spares the quadriceps. The incidence of this form is about 10 per million per year.

What are hereditary myosin myopathies?

Hereditary myosin myopathies have emerged as a new group of muscle diseases with highly variable clinical features and onset during fetal development, childhood or adulthood. They are caused by mutations in skeletal muscle myosin heavy chain (MyHC) genes. Mutations have been reported in two of the t …

What is Desmin-related myofibrillar myopathy (IBM1)?

The condition now called Desmin-related myofibrillar myopathy (also called myofibrillar myopathy-1) was formerly known as inclusion body myopathy 1 (IBM1). More types of HIMBs, linked to other genes, may be identified in the future.
