Presentation
With the present work, it is proposed a new approach for the LGMD2A diagnostic analysis, combining molecular genetics and protein analysis methodologies in order to contribute to a differential diagnostic essential for global characterization of patients [repositorio.insa.pt]

LGMD2J (titinopathy) This form of LGMD occurs when two titin gene mutations are present and has a variable age of onset ranging from 10-30 years. Affected individuals have severe progressive proximal muscle weakness. [rarediseases.org]

Muscle weakness may be associated with soreness in the muscles and joint pain. [rarediseases.org]
Some patients may need assisted ventilation to treat respiratory muscle weakness and a pacemaker for cardiac abnormalities. [ninds.nih.gov]
Muscular dystrophies are a group of inherited muscle disorders in which one or more genes needed for normal muscle structure and function are defective, leading to muscle weakness of varying severity. [msdmanuals.com]
They all cause muscle weakness and muscle loss. Some forms of MD appear in infancy or childhood. Others may not appear until middle age or later. The different types can vary in whom they affect, which muscles they affect, and what the symptoms are. [icdlist.com]

Workup
Lack of dystrophin leads to cellular instability at these links, with progressive leakage of intracellular components; this results in the high levels of creatine phosphokinase (CPK) noted on routine blood workup of patients with Duchenne MD. [emedicine.medscape.com]
Treatment
Treatment There is no specific treatment to stop or reverse any form of MD. Treatment may include physical therapy, respiratory therapy, speech therapy, orthopedic appliances used for support, and corrective orthopedic surgery. [ninds.nih.gov]
The only treatment for muscle weakness is supportive measures, such as ankle braces (for footdrop) and other devices. [msdmanuals.com]

Etiology
Conclusion: Muscular dystrophies are a heterogeneous group of diseases that share a common etiology due to direct injury of the muscle fiber with a progressive and systemic compromise. [journals.lww.com]

Prevention
Prevention - Muscular dystrophy limb girdle type 2A- Erb type Physical therapy and stretching exercises can prevent contractures and muscle atrophy and thus help to slow disease progression. [checkorphan.org]
Allow for frequent rest periods; cluster care activities to prevent overtiring the patient. [quizlet.com]
Maintenance of function and prevention of contractures Treatment of limb-girdle dystrophy is focused on maintaining muscle function and preventing the muscles from freezing in permanent, flexed positions called contractures. [msdmanuals.com]
Treatments can help with the symptoms and prevent complications. They include physical and speech therapy, orthopedic devices, surgery, and medications. Some people with MD have mild cases that worsen slowly. Others cases are disabling and severe. [icdlist.com]
