Mitochondrial Myopathies (MM) - Diseases - Muscular …
WebMitochondrial 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.
Mitochondrial myopathy - Wikipedia
WebMitochondrial myopathies are types of myopathies associated with mitochondrial disease. Adenosine triphosphate ( ATP ), the chemical used to provide energy for the cell, cannot be produced sufficiently by oxidative phosphorylation when the mitochondrion is either damaged or missing necessary enzymes or transport proteins.

WebNov 7, 2018 · Mitochondrial myopathies are progressive muscle conditions caused primarily by the impairment of oxidative phosphorylation (OXPHOS) in the mitochondria. This causes a deficit in energy production in the form of adenosine triphosphate (ATP), particularly in skeletal muscle.
Mitochondrial Myopathy | Children's Hospital of Philadelphia
WebMitochondrial myopathies are forms of mitochondrial disease that cause prominent muscle problems, a grouping based on both symptoms and non-genetic clinical tests. Three types of muscles can be affected by the myopathy: Skeletal — the muscles around the bones and eyes. Cardiac — the heart muscles.

Mitochondrial myopathies: Clinical features and diagnosis
WebJan 29, 2024 · INTRODUCTION. Mitochondrial diseases present with a wide range of clinical expression. Organ systems relying most on aerobic metabolism are preferentially affected and involvement of the nervous system is common. When skeletal muscle is affected, either alone or with central nervous system disease, the term mitochondrial myopathy is used.
Mitochondrial Myopathies (MM) - Muscular Dystrophy Association
WebThe main symptoms of mitochondrial myopathies are muscle weakness and atrophy (shrinking) and exercise intolerance. Furthermore, mitochondrial disorders can occasionally present only with these muscle symptoms and elevated or normal serum creatine kinase (CK), myalgia, or, less often, rhabdomyolysis (toxic muscle breakdown).
Diagnosis and treatment of mitochondrial myopathies - PMC
WebAug 25, 2011 · Mitochondrial disorders are a heterogeneous group of disorders resulting from primary dysfunction of the respiratory chain. Muscle tissue is highly metabolically active, and therefore myopathy is a common element of the clinical presentation of these disorders, although this may be overshadowed by central neurological features.
