Mitochondrial myopathies are types of myopathies associated with mitochondrial disease. [1] 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.
Inclusion body myositis (IBM) (/ m aɪ oʊ ˈ s aɪ t ɪ s /) (sometimes called sporadic inclusion body myositis, sIBM) is the most common inflammatory muscle disease in older adults. [2] The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso) and distal muscles (close ...
CPEO is the most common manifestation of mitochondrial myopathy, occurring in an estimated two-thirds of all cases of mitochondrial myopathy. Patients typically present with ptosis (drooping eyelids). Other diseases like Graves' disease, myasthenia gravis and glioma that may cause an external ophthalmoplegia must be ruled out.

Some GSDs and a mitochondrial myopathy are known to have a pseudoathletic appearance. McArdle disease (GSD-V) and late-onset Pompe disease (GSD-II) are known to have hypertrophy, particularly of the calf muscles. [14] [15] Cori/Forbes disease (GSD-III) is known to have hypertrophy of the sternocleidomastoid, trapezius, quadriceps, and thigh ...
Mitochondrial disease can manifest in many different ways [1] whether in children [2] or adults. [3] Examples of mitochondrial diseases include: Mitochondrial myopathy [2] [3] Maternally inherited diabetes mellitus and deafness (MIDD) [4] While diabetes mellitus and deafness can be found together for other reasons, at an early age this ...
Mitochondrial trifunctional protein deficiency; Other names: TFP deficiency [1] Mitochondrial trifunctional protein deficiency has an autosomal recessive pattern of inheritance: Symptoms: Cardiomyopathy, skeletal myopathy [2] Types: Mutations in the HADHA and HADHB gene [2] Diagnostic method: CBC, Urine test [3] Treatment: Low fat diet, Limited ...
In medicine, myopathy is a disease of the muscle [1] in which the muscle fibers do not function properly. Myopathy means muscle disease (Greek : myo- muscle + patheia -pathy : suffering). This meaning implies that the primary defect is within the muscle, as opposed to the nerves ("neuropathies" or "neurogenic" disorders) or elsewhere (e.g., the ...
Distal muscular dystrophy, also called distal myopathy, is essentially any muscle disease that preferentially affects the hands and/or feet, a much less common pattern than proximal muscle weakness. Late adult-onset type 1; Late adult-onset type 2a; Late adult-onset type 2b; Early adult-onset type 1; Early adult-onset type 2; Early adult-onset ...
