Are mitochondrial myopathies curable?
There are no cures for mitochondrial diseases, but treatment can help reduce symptoms or slow the decline in health. Treatment varies from patient to patient and depends on the specific mitochondrial disease diagnosed and its severity.
What is mitochondrial myopathy caused by?
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.
Is mitochondrial myopathy a rare disease?
A rare, genetic, mitochondrial DNA -related mitochondrial myopathy disorder characterized by slowly progressive muscular weakness (proximal greater than distal), predominantly involving the facial muscles and scapular girdle, associated with insulin-dependent diabetes mellitus .
Can mitochondrial myopathy be prevented?
In a possible first, the heritable transmission of a fatal mitochondrial DNA disease (Leigh syndrome) may have been prevented by replacing the mutation-bearing mitochondria of oocytes with donated mutation-free counterparts.
How long do you live with mitochondrial disease?
A small study in children with mitochondrial disease examined the patient records of 221 children with mitochondrial disease. Of these, 14% died three to nine years after diagnosis. Five patients lived less than three years, and three patients lived longer than nine years.
Is mitochondrial myopathy a terminal?
If a lot of Mitochondria in the body are affected, especially in important body organs, mitochondrial disease can be very serious and often fatal.
How is mitochondrial myopathy treated?
Although there is no specific treatment for any of the mitochondrial myopathies, physical therapy may extend the range of movement of muscles and improve dexterity.
How long can you live with mitochondrial myopathy?
What is the prognosis of mitochondrial myopathy?
The prognosis for these disorders ranges in severity from progressive weakness to death. Most mitochondrial myopathies occur before the age of 20, and often begin with exercise intolerance or muscle weakness. During physical activity, muscles may become easily fatigued or weak. Muscle cramping is rare, but may occur.
