Autosomal Recessive Limb-Girdle Muscular Dystrophy Type 2A

LGMD2A


Presentation

  • We report a 33-year-old woman with initial presentations of exercise intolerance and running difficulty at age 15 years. At presentation, waddling gait, positive Gowers' sign, and marked muscle atrophy in pelvic and leg muscles were noted.[ncbi.nlm.nih.gov]
  • Abstract Limb-girdle muscular dystrophies (LGMDs) are a group of neuromuscular diseases presenting great clinical heterogeneity.[ncbi.nlm.nih.gov]
  • In the present study, whole exome sequencing was performed on six unrelated Iranian families who presented with progressive muscle weakness, with a strong suspicion of Calpainopathies.[uniprot.org]
  • . * 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]
Difficulty Walking
  • COMMON Features of the Disorder Difficulty walking Wheelchair assistance Scoliosis Joint contractures Muscle cramps Exercise intolerance Cardiomyopathy (weak heart muscles) Breathing problems PROGNOSIS Individuals can be affected to different degrees,[evolvegene.com]
  • Get Update Overview Autosomal recessive limb-girdle muscular dystrophy-1 affects primarily the proximal muscles, resulting in difficulty walking. The age at onset varies, but most patients show onset in childhood, and the disorder is progressive.[diseaseinfosearch.org]

Positive Gower's Sign
  • At presentation, waddling gait, positive Gowers' sign, and marked muscle atrophy in pelvic and leg muscles were noted.[ncbi.nlm.nih.gov]

Prognosis

  • However, the prognosis is highly variable even within family members. The age of onset also varies and can range from early childhood to adulthood.[cags.org.ae]
  • COMMON Features of the Disorder Difficulty walking Wheelchair assistance Scoliosis Joint contractures Muscle cramps Exercise intolerance Cardiomyopathy (weak heart muscles) Breathing problems PROGNOSIS Individuals can be affected to different degrees,[evolvegene.com]
  • 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]
  • 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]
