41. Because myosin II are essential for muscle contraction, defects in muscular myosin predictably cause myopathies . 42. This condition is now known as dynamin 2 centronuclear myopathy ( abbreviated DNM2-CNM ). 43. Centronuclear myopathies involve pathology at the skeletal muscles, generally without brain involvement or cognitive deficits. 44. The foundation raises funds for medical research of myotubular myopathy , and other related congenital myopathies. 45. The foundation raises funds for medical research of myotubular myopathy, and other related congenital myopathies . 46. In moderate active disease, the signs and symptoms are persistent and increasing and include myopathy . 47. Serum creatine kinase is elevated in Bethlem myopathy , as there is ongoing muscle cell death. 48. He developed myopathy , nystagmus, ataxia, upper motor neuron signs, and absence seizures. 49. Further research led Natterson-Horowitz to equate capture myopathy with the human condition Takotsubo cardiomyopathy. 50. Because these forms do not show inflammation, they are classified as myopathies and not myositis types.
