Presentation
This form of muscular dystrophy presents with weakness of the pelvic and shoulder girdle in infancy or childhood, with symptoms usually present by the age of 12 years. Progression is rapid, and patients are usually wheelchair-bound in adolescence. [sema4genomics.com]
Exercise-induced cramps may be present. Calf hypertrophy affects some patients. Adults usually remain ambulant. Causes - Limb-girdle muscular dystrophy- type 2C Muscular dystrophy is caused by various genetic mechanisms. [checkorphan.org]
In the present investigation, we combined microspectrofluorimetry and electron microscopy techniques to investigate the physiological function and the ultrastructure of control and LGMD2C myotubes. [ncbi.nlm.nih.gov]
They often present with both weakness and sensory loss in a “ glove and stocking” fashion. [lecturio.com]

Children walk with waddle and exhibit lordosis. Cardiac involvement is known but not as common or prominent as in dystrophinopathies. [annalsofian.org]

Neurologic
- Gowers Sign
Mild to moderate elevated serum creatine kinase levels and positive Gowers sign are reported. [orpha.net]

Monarch’s tools are designed to make it easier to compare the signs and symptoms (phenotypes) of different diseases and discover common features. [rarediseases.info.nih.gov]
Is there a finding (or history) of Gower's sign? This is seen in patients with proximal muscle weakness of the lower limb: when rising to stand, they use the hands as support, such that the hands 'climb up the legs'. [patient.info]

Workup
[…] molecular diagnosis is not worldwide available, and since a huge clinical variability can be observed in all forms of LGMDs, protein techniques with commercially available anti-telethonin antibodies should be introduced in a routine basis in the diagnostic workup [bmcclinpathol.biomedcentral.com]

A team of doctors or specialists is often needed to figure out the treatment options for each person. [1] Last updated: 8/9/2016 How might limb-girdle muscular dystrophy, type 2C (LGMD2C) be treated? There is no specific treatment for LGMD2C. [rarediseases.info.nih.gov]

The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment. [orpha.net]
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 - Limb-girdle muscular dystrophy- type 2C Patients may also present with elevated CK levels without weakness but with myalgia and cramps, distal weakness, hypertrophic cardiomyopathy, or rippling-muscle disease. [checkorphan.org]
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]

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]
We ascertained a family in which five siblings presented with distal muscle weakness of unknown etiology. [scinapse.io]

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]
Epidemiology
This prompted us to search the scientific literature since 1990 for the epidemiology of NMDs. Objectives: To study occurrence rates, gender and age distribution. [scinapse.io]

Classification and epidemiology All form of LGMD are inherited autosomally and the classification is alphanumeric with assignation of number ‘1’ or ‘2’ depending on whether they are inherited dominantly or recessively. [content.iospress.com]
Pathophysiology

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
Management of the condition is based on each person's symptoms and may include: [4] Weight control to avoid obesity Physical therapy and stretching exercises to promote mobility and prevent contractures Use of mechanical aids such as canes, walkers, orthotics [rarediseases.info.nih.gov]
Prevention - Limb-girdle muscular dystrophy- type 2C Not supplied. Diagnosis - Limb-girdle muscular dystrophy- type 2C Not supplied. [checkorphan.org]
Some of the complications can be prevented with appropriate treatment. For example, a cardiac pacemaker or defibrillator can greatly reduce the risk for sudden death due to an abnormal heart rhythm. [medlineplus.gov]
This would entail close surveillance to recognize symptoms and to prevent detrimental sequelae. 2. [pubs.sciepub.com]
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]
