Nemaline Myopathy Type 2

NM2

Neuromuscular syndromes are presented clinically either as a case study or as an overview from the literature, accompanied by text presenting molecular defects, and differential diagnosis. [books.google.com]

Although some patients did not reach adult age, we present here a case who had several episodes of respiratory insufficiency but reached age 50 with very thin body bulk and, at difference with other cases, presented extraocular muscle involvement. [link.springer.com]

Most episodes presented after feeding and were aborted by stimulation. Upon admission to ICU, hypotension and respiratory acidosis were detected and orotracheal intubation and mechanical ventilation initiated. [jnnp.bmj.com]

  • Difficulty Running

    The severity and pattern of muscle weakness varies, but most affected individuals show mildly delayed motor development, hypotonia, generalized muscle weakness, and weakness of the proximal limb muscles and neck muscles, resulting in difficulty running [diseaseinfosearch.org]

    You’re spelling words, “cat, dog, fish, Ethan…” and trying to mimic us when we speak. You’re learning to speak through an AAC app and learning more sign language words than I can count. (We suspect you’re creeping up to 100 words!) [themighty.com]

  • Chest Deformity

    Most patients were characterized by similar clinical features, such as high-arched palate, long fingers, elongated myopathic face, chest deformity, dysphagia, respiratory insufficiency, and bulbar muscle weakness. [link.springer.com]

    Patients may also exhibit dysphagia, respiratory insufficiency, foot deformities, arch palate, scoliosis, chest deformities and superior and inferior limbs contractures 1-7. [scielo.br]

  • Muscle Contracture

    contractures, most probably because of the hypercontractility caused by the mutant protein in nemaline myopathy and/or core-rod myopathy patients. 21 TNNT1 : a recessive nonsense founder variant is present in the Old Order Amish population. [nature.com]

  • Lordosis

    Scoliosis and lordosis pose technical difficulties with regard to regional anesthesia. Post delivery, women with nemaline myopathy need social support systems for mobilization and care of newborn. [neurologyindia.com]

  • Hyporeflexia

    Diagnosis is made based upon clinical signs such as muscle weakness, absent or low deep tendon reflexes (hyporeflexia), and a high-arched palate, along with electron-dense aggregates, called nemaline rods, being observed at the microscopic level within [en.wikipedia.org]

    People with X-linked myotubular myopathy may also have weakness in the muscles that control eye movement (ophthalmoplegia), weakness in other muscles of the face, and absent reflexes (areflexia).In X-linked myotubular myopathy, muscle weakness often disrupts [icdlist.com]

  • Dysphasia

    After treatment with pyridostigmine, prednisome, and azathioprine, dysphasia, dysarthria, and ptosis were mildly alleviated. Recently, the patient presented exacerbating weakness in proximal muscles of the limbs with obvious muscle fasciculation. [journals.lww.com]

  • Forgetful

    I’ll never forget the moment your doctor and team brought us into this little, windowless room off the PICU. The picture they painted of your future felt bleak. [themighty.com]

We conclude from this study that MFMs ultrastructural findings can direct diagnostic efforts towards the causal gene mutated, and that EM should be included in the diagnostic workup of MFMs. [institut-myologie.org]
