| Muscle filaminopathy is a rare myofibrillar myopathy characterized by slowly progressive, proximal skeletal muscle weakness, which is initially more prominent in lower extremities and involves upper extremities with disease progression. Patients present with difficulty climbing stairs, a waddling gait, marked winging of scapula, lower back pain, paresis of limb girdle musculature, hypo-/areflexia and/or mild facial muscle weakness in rare cases. Respiratory muscle weakness is common and cardiac anomalies (conduction blocks, tachycardia, diastolic dysfunction, left ventricular hypertrophy) have been reported in some cases. |

|
| Spheroid body myopathy is a rare form of myofibrillar myopathy characterized by predominantly proximal muscle weakness (that could be either non- or slowly progressive), associated with spheroid body inclusions (composed of myofilament material within individual muscle fibers) in skeletal muscle biopsy. Presentation is varied and may range from asymptomatic to severe muscle weakness that manifests with absent Achilles reflexes, gait abnormality and/or other motor incapacitations. |

|
| A rare, genetic, non-dystrophic myofibrillar myopathy disorder characterized by late-adult onset of distal and/or proximal limb muscle weakness with initial involvement of posterior lower leg muscles, medial gastrocnemius and soleus. Patients present with ankle weakness followed by weakness of finger and wrist extensors and later on of proximal muscles. Ambulation is usually preserved. Late-onset associated cardiomyopathy and/or neuropathy has been reported in a minority of cases. |

|
| A rare genetic skeletal muscle disease characterized by abnormal chimeric aggregates of desmin and other cytoskeletal proteins and granulofilamentous material at the ultrastructural level in muscle biopsies and variable clinical myopathological features, age of disease onset and rate of disease progression. Patients present with bilateral skeletal muscle weakness that starts in distal leg muscles and spreads proximally, sometimes involving trunk, neck flexors and facial muscles and often cardiomyopathy manifested by conduction blocks, arrhythmias, chronic heart failure, and sometimes tachyarrhythmia. Weakness eventually leads to wheelchair dependence. Respiratory insufficiency can be a major cause of disability and death, beginning with nocturnal hypoventilation with oxygen desaturation and progressing to daytime respiratory failure. |

|
| A rare genetic skeletal muscle disease with characteristics of muscle stiffness and rigidity, hypertonia, weakness, respiratory distress and normal cognition. Patients have persistently elevated creatine kinase and histopathology is typical of myofibrillar myopathy. The manifestation onset follows the short period of normal infantile development and leads to progressive respiratory insufficiency and early death. There is the disease is caused by homozygous mutation in the CRYAB gene on chromosome 11q23. |

Some |
|
| A rare genetic disease with characteristics of adult-onset myofibrillar myopathy variably associated with cardiomyopathy and/or posterior pole cataracts. Patients typically present progressive proximal and distal muscle weakness and wasting of lower and upper limbs, often with velopharyngeal involvement including dysphagia, dysphonia and ventilatory insufficiency. Electromyography shows myopathic features and muscle biopsy reveals myofibrillar myopathy changes. Caused by heterozygous mutation in the alpha-B-crystallin gene (CRYAB) on chromosome 11q23. |

|
| A rare genetic skeletal muscle disease characterized by neonatal to childhood onset of slowly progressive muscle weakness and atrophy primarily affecting the lower limbs, joint contractures, kyphosis or lordosis of the spine, lateral tongue atrophy, and pes equinus. Progression to upper limb involvement, facial weakness, language impairment, intellectual disability, and behavioral abnormalities have been reported in addition. Muscle biopsy shows myopathic changes with increased fiber size variation, internalized nuclei, fiber atrophy, as well as rod structures and core targetoid defects. |

| A rare defect of tropomyosin characterized by decreased fetal movements and generalized muscle stiffness at birth. Additional features include joint contractures, short stature, kyphosis, dysmorphic features, temperature dysregulation, and variably severe respiratory involvement with hypoxemia. Muscle biopsy shows mild myopathic features. |

| A rare genetic neuromuscular disease characterized by length-dependent axonal motor neuropathy predominantly affecting the lower limbs, in combination with a myopathy with morphological features of myofibrillar myopathy with aggregates and rimmed vacuoles. Age of onset is typically in the second to third decade of life. Patients present with slowly progressive muscle weakness and atrophy initially affecting the distal lower limbs and later progressing to involve proximal limbs and also truncal muscles. There is no involvement of respiratory and cardiac muscles. |
