Weight Loss
  • AFFECTED (those having 2 copies of the mutation and will likely begin to show weight loss, muscle weakness and exercise intolerance after a few months of age.[vetdnacenter.com]
  • Other early symptoms indicating poor muscle tone and muscular weakness are a lack of spontaneous movement, inability to balance the head and a weak cry. The child often feels “floppy” and slack when lifted or carried.[socialstyrelsen.se]

  • Prognosis is often determined by respiratory, orthopedic, and bulbar involvement. Over the past decade, a number of causative genes have been identified for congenital myopathies.[neurologyindia.com]
  • In recent years, MDA-supported scientists have learned that centronuclear myopathies encompass a larger group of diseases than just X-linked myotubular myopathy, and that these types often have a better prognosis than the X-linked type.[mda.org]

  • Dystrophin prevents the membrane that lines the muscle fiber (plasmalemma) from tearing when the muscle contracts. In DMD patients, very little dystrophin or dystrophin-like proteins exist.[healthcommunities.com]
  • Medical management generally involves efforts to prevent pulmonary complications, since lung infections can be fatal in patients lacking the muscle strength necessary to clear secretions via coughing.[en.wikipedia.org]
  • A physiotherapist can give advice and instructions on different exercises to prevent stiffness recurring. A spinal brace can stabilise the trunk and counteract scoliosis (curvature of the spine).[socialstyrelsen.se]
