Presentation
They often present with both weakness and sensory loss in a “ glove and stocking” fashion. [lecturio.com]
* About two thirds of patients present at 8-15 years of age, with a range of 2-40 years. * The most typical presentation is of weakness due to scapular-humeral-pelvic weakness that may be similar to the presentation of facioscapulohumeral dystrophy. [checkorphan.org]
Cardiac disease may be present in up to 33%. [emedicine.medscape.com]
This form of muscular dystrophy presents with weakness of the pelvic and shoulder girdle in childhood, with symptoms usually present by the age of 10 years. [sema4genomics.com]
Only the first and second heart sounds were present. The lung fields were clear and the liver was not palpable. [chs-journal.com]

Musculoskeletal
- Proximal Muscle Weakness
In addition to proximal muscle weakness, there may or may not be: Distal muscle weakness. Muscle hypertrophy. Contractures. Involvement of the heart, respiratory muscles or tongue. (Facial weakness is not usual.) [patient.info]
Proximal muscles are the muscles that are closest to the center of the body such as the muscles of the shoulder, pelvis, and upper arms and legs. Muscle weakness may spread from the proximal muscles to affect distal muscles. [rarediseases.org]
Hypothyroid myopathy Patients can present with a proximal weakness. They may complain of fatigue or muscle pain and cramping. They have relaxation of the reflexes at an advanced stage of the disease. [lecturio.com]
In this study, we applied the IDP on a PGM to diagnose a Vietnamese female who presented with proximal muscle weakness. Using this strategy, we identified a nonsense mutation in CAPN3 responsible for LGDM2A. [omicsonline.org]

Workup
See Workup for more detail. Management No specific treatment is available for any of the LGMD syndromes, though aggressive supportive care is essential to preserve muscle function, maximize functional ability, and prolong life expectancy. [emedicine.medscape.com]
Treatment
Treatment: No treatment other than physical therapy is available. Prognosis: Most patients live into adulthood but progression is inevitable and all individuals eventually become totally disabled. [wohproject.org]
There is no specific treatment for LGMD2C. [rarediseases.info.nih.gov]
Treatment and management So far there are no specific treatments for LGMD2I, however managing the symptoms of the condition improves a person’s quality of life. Keeping mobile is important for all people affected with muscular dystrophy. [lgmd2i.com]
Prognosis
The symptoms are similar to DMD but often milder, and patients are less likely to have mental retardation and have a better prognosis (30-40 years instead of teens). [lecturio.com]
Prognosis and management, therefore, are not uniform across the subtypes of LGMD2. Nonetheless, early identification of complications and risk factors is crucial. [mdfgauteng.org]
Prognosis: Most patients live into adulthood but progression is inevitable and all individuals eventually become totally disabled. Ancillary treatments and support: Respiratory therapy is important when diaphragmatic weakness becomes prominent. [wohproject.org]
Contractures are common, in which case the disease needs to be differentiated from Emery-Dreifuss muscular dystrophy, Bethlem myopathy, and laminin-alpha2 deficiency Prognosis - Limb-girdle muscular dystrophy type 2A This depends upon the type. [checkorphan.org]
Prognosis The prognosis of LGMD varies tremendously. Most people with LGMD, however do not have severe symptoms and most experience a normal lifespan. Cardiac and respiratory difficulties can, however, decrease the lifespan. [encyclopedia.com]
Etiology
During the visit, the participant will be asked to fill out a couple of questionnaires asking questions about quality of life and activity limitations, as well as his/her understanding of their diagnosis with regards to etiology (or cause of their muscle [clinicaltrials.gov]
Etiology Currently, there are more than 30 different known LGMDs including the eight dominant (LGMD1A-H) and 23 recessive (LGMD2A-Y) types. [now.aapmr.org]

Pathophysiology
Pathophysiology Limb-girdle muscular dystrophy (LGMD) protein defects occur in several pathways involved in the biologic function of muscle and can be divided into groups based on cellular localization. [emedicine.medscape.com]
The pathophysiological role of calpain-3 is not exactly known. Immunohistochemical (IHC) analysis of calpainopathy is still not possible as there is no anti-calpain-3 antibody available that is compatible for IHC on muscle biopsy cryosections. [neurologyindia.com]
Prevention
This would entail close surveillance to recognize symptoms and to prevent detrimental sequelae. 2. [pubs.sciepub.com]
Prevention - Limb-girdle muscular dystrophy type 2A Not supplied. [checkorphan.org]
A physiotherapist can recommend stretches to keep joints supple and if necessary special splints (orthoses) to prevent muscle shortening (contractures) which are common in some types of LGMD. [mda.org.au]
Carriers do not have any symptoms since they have one unchanged gene, which produces enough normal protein to prevent the symptoms of LGMD. [encyclopedia.com]
Pneumovax vaccination and annual flu immunization should be performed in people affected by LGMD2I in order to prevent serious chest infections. [lgmd2i.com]
