  Some cases of LGMD may have onset during adulthood, mild symptoms, and slow progression; others may have onset during childhood and early severe disability such as difficulty climbing stairs and walking. [rarediseases.org]

• Severe Clinical Course

  Patients with LGMD 2C–F predominantly have a severe clinical course 4, 5, 6, 7, 8, 13, 14, 15, 18, 19, 20. The LGMD 2G locus maps to a 3-cM interval in 17q11–12 in two Brazilian families with a relatively mild form of AR LGMD (ref. 9 ). [nature.com]

  Early childhood onset of LGMD2I usually indicates a severe clinical course with affected individuals needing a wheelchair by the second decade. There is overlap with a congenital form of muscular dystrophy, MDC1C. [rarediseases.org]

• Calf Hypertrophy

  Mild scapular winging, calf hypertrophy, and lack of respiratory and cardiac involvement are also observed.Visit the Orphanet disease page for more resources. [malacards.org]

  Asymmetric calf hypertrophy is a common sign. Heart involvement is not rare. Serum CK is 3-fold to 30-fold increased. Muscle biopsy shows a dystrophic pattern, including rimmed vacuoles. [link.springer.com]

  Mild scapular winging, calf hypertrophy, and lack of respiratory and cardiac involvement are also observed. Last updated: 4/1/2017 This table lists symptoms that people with this disease may have. [rarediseases.info.nih.gov]

  The predominant involvement of pelvic girdle muscles with calf hypertrophy observed in LGMD2G resembles the phenotype of some LGMD-2I. [journals.plos.org]

  Other symptoms may include the following: Asymmetric or distal weakness (rare) Respiratory failure Cardiomyopathy, cardiac arrhythmias Scapular winging Calf hypertrophy Contractures/rigid spine See Clinical Presentation for more detail. [emedicine.medscape.com]

• Tremor

  Differently from other LGMD2G patients, however, he presented tremor on the hands at his first examination, which significance in the myopathic context of his disease is still not clear. [bmcclinpathol.biomedcentral.com]

• Spastic Paraplegia

  Six new chapters cover congenital myasthenic syndromes, hereditary spastic paraplegia, ion channel disorders, the phakomatoses, beta-galactosidase deficiency, and prion diseases. [books.google.com]

• Hyperactivity

  Perhaps fiber necrosis may be secondary to a defect in sarcomeric regulation with accumulation of fiber degradation products and possible lysosomal hyperactivity. [bmcclinpathol.biomedcentral.com]

• Excitement

  Pascual is interested in the molecular mechanisms that cause inherited metabolic and excitability disorders using electrophysiology and nuclear magnetic resonance both in human subjects and in models of human diseases. [books.google.de]

[…] 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]

Appropriate diagnosis in these cases is important for genetic counseling and prognosis. [bmcclinpathol.biomedcentral.com]

Chronic pain can occur, and pain management should be part of care. [ 19 ] Prognosis This depends on the type of LGMD and whether there is cardiac or respiratory involvement. In general, all types of LGMD progress with time. [patient.info]
