Limb-Girdle Muscular Dystrophy Type 1E

LGMDD1


Presentation

  • […] and only minor CNS abnormalities Fukutin LGMD 2 N Usually presents in infancy as Muscle-Eye-Brain disease but can present in early adult life with proximal weakness and only minor CNS abnormalities POMGn T1 LGMD 2O Usually presents in infancy as Walker[jcdr.net]
  • They often present with both weakness and sensory loss in a “ glove and stocking” fashion.[lecturio.com]
  • Cardiac disease may be present in up to 33%.[emedicine.medscape.com]
  • A 35-year-old man presents to his primary care physician's office for difficulty chewing and walking and mild musclar pain. He notices himself dragging his feet while walking and pain in his legs. He experiences stiffness in his jaw and his hands.[medbullets.com]
  • Only the first and second heart sounds were present. The lung fields were clear and the liver was not palpable.[chs-journal.com]
Difficulty Climbing Stairs
  • LGMD1 patients may need to use walking aids, can have difficulties climbing stairs and lose the ability to walk. Creatine kinase (CK) levels can be normal to moderately elevated.[mdfgauteng.org]
  • Symptoms that might be noticed first include frequent falls and difficulty climbing stairs, running and rising from the floor.[mda.org.au]
Long Arm
  • A genomewide scan identified a region on the long arm of chromosome 6 that is significantly associated with the presence of myopathy (D6S262; maximum LOD score [Z(max)] 4.99 at maximum recombination fraction [theta(max)] .00), identifying FDC-CDM as a[ncbi.nlm.nih.gov]

Gowers Sign
  • Image : “Gower’s sign.” by William Richard Gowers (1845–1915) – Gowers WR. Clinical lecture on pseudohypertrophic muscular paralysis. Lancet 1879;ii,73-5.[lecturio.com]
  • Gower’s sign was positive. Winging of scapula was present. Power was 3/5 at both shoulders, 4/5 at both elbows, 5/5 at both wrists, 3/5 at both hip joints, 3/5 at both knees, 5/5 at both ankles.[jcdr.net]
  • In his adolescence, he developed proximal leg weakness with Gowerssign (i.e., with hip girdle weakness, the patient arises from a stooped or a squatting position by using his hands to “climb up the legs”).[bmcresnotes.biomedcentral.com]

Treatment

  • Part one discusses the approach to neuromuscular disorders, covering principles and basics, neuromuscular investigations, and assessment and treatment of neurological disorders.[books.google.com]
  • In acquired myopathies, treatment is targeted toward the underlying cause. Treatment of statin myopathies is dependent on creatine phosphokinase levels and degree of muscle symptoms. Consider lower doses when initiating statin therapy.[clevelandclinicmeded.com]
  • More detailed information about the symptoms, causes, and treatments of Limb-girdle muscular dystrophy type 2C is available below.[checkorphan.org]
  • Early and prompt treatment and early surveillance is much better than waiting for problems to occur and then trying to deal with them.[treat-nmd.eu]
  • You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.[rarediseases.info.nih.gov]

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]
  • […] autosomal dominant mutation in DMPK gene on chromosome 19 leads to a CTG trinucleotide expansion Pathogenesis unclear, but it is believed that the abnormal mRNA transcript of DMPK impairs RNA splicing, which leads to missplicing of other RNA transcripts Prognosis[medbullets.com]
  • 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]

Pathophysiology

  • Back to Top Pathophysiology Disruption of the structural integrity and metabolic processes of muscle cells can result from genetic abnormalities, toxins, inflammation, infection, and hormonal and electrolyte imbalances.[clevelandclinicmeded.com]
  • Multiple functions are described, but the pathophysiologic basis for LGMD1B is unknown.[emedicine.medscape.com]

  • Thus, although no current guidelines are available, oral anticoagulant is advisable in such cases with AF for stroke prevention.[bmcresnotes.biomedcentral.com]
  • 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]
  • 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]
