Presentation
Advances in clinical and genetic characterization of minicore myopathy have revealed an expanded clinical spectrum, with a minority of affected children presenting in early infancy with severe muscle weakness. [medlink.com]
The most common type of nemaline rod myopathy presents in the infantile stage with 42% of patients presenting in the neonatal period. [6] While there has been an association with polyhydramnios, decreased fetal movements, and an abnormal fetal presentation [emedicine.medscape.com]
The condition has kept stable up to present [Fig 2 a-c]. DISCUSSION MmD usually presents as congenital myopathy2-7 rarely as adult-onset disease12. [scielo.br]
All were male and presented in early childhood (first decade of life) with generalized hypotonia and muscle weakness. All of them had dysmorphic facies and three had high arched palate. [neurologyindia.com]

Minicore myopathy, also called, multicore myopathy and multiminicore myopathy, falls under the umbrella of congenital myopathies. These are a group of conditions characterised by muscle weakness and wasting. [musculardystrophyuk.org]

- Muscle Weakness
In this form, the muscles of the ribcage and spine become stiff. In addition, the muscles needed for breathing are weak. This combination of muscle weakness and stiffness leads to severe or life-threatening respiratory problems. [medlineplus.gov]
Muscle weakness: Muscles in your child’s neck, shoulders and pelvis (proximal muscles) are most commonly affected. Difficulty breathing: Feeling short of breath or like you can’t fill your lungs with air because of the weakness of breathing muscles. [my.clevelandclinic.org]
Neurological examination failed to demonstrate muscle weakness in the son in whom only mild hypotonia was found. In the mother, mild weakness was detected in the neck flexors and proximal muscles of the lower limbs. [jnnp.bmj.com]
None of our patient had ptosis, bulbar weakness or hand muscle weakness. [neurologyindia.com]
Muscle weakness normally affects the proximal muscles, which are those muscles closest to the center of the body such as the muscles of the shoulder, pelvis and upper arms and legs. [rarediseases.org]
Neurologic
- Tremor
Early compensation at birth may be due to fetal transcription of TNNT2 and TNNT3. [21] Onset is during the first few months of life with hypotonia, proximal weakness as well as jaw and limb tremors that resolve over a few months. [emedicine.medscape.com]

Treatment
Is there a treatment? Currently there is no treatment for minicore myopathy although management of the condition is very important. [musculardystrophyuk.org]
Treatment for all types of congenital myopathy involves managing your child’s symptoms. These treatments should include: Orthopedic treatment, if needed. Physical therapy. Occupational therapy. Speech therapy. [my.clevelandclinic.org]
Standard Therapies Treatment The treatment of central core disease (CCD) is directed toward the specific symptoms that are apparent in each individual. [rarediseases.org]
Aggressive treatment of lower respiratory infections is critical. [ncbi.nlm.nih.gov]
Prognosis
Outlook / Prognosis What can I expect if my child has congenital myopathy? The prognosis for congenital myopathy varies greatly depending on the type and severity of your child’s condition. [my.clevelandclinic.org]
Nocturnal ventilation, when indicated, may significantly improve the prognosis. Assessment of cardiac status because of the risk of cardiac impairment secondary to respiratory involvement Growth should be assessed regularly. [ncbi.nlm.nih.gov]
Worse prognosis has also been associated with respiratory insufficiency due to weakness of diaphragm and accessory respiratory muscles and/or thoracic deformities6. [scielo.br]
Although the diagnosis of either affection may not necessarily lead to a specific treatment, the prevention of life threatening complications, the development of supportive and symptomatic therapies, and adequate information concerning prognosis can be [jnnp.bmj.com]
Most cases are inherited as autosomal dominant trait and associated with nonprogressive muscle disease and a favorable prognosis. Some cases are inherited as autosomal recessive traits and are more likely to be associated with severe complications. [rarediseases.org]

Pathophysiology
Determining the genetic defect in these patients will help to clarify the pathophysiological alterations that lead to fibre type disproportion. Myalgia was not a feature in previously described patients with multicore disease. [jnnp.bmj.com]

Prevention
A feeding tube prevents this from happening. There are a number of different types of feeding tube which are available, and these are fitted by a short surgical procedure. [musculardystrophyuk.org]
Prevention How can I reduce my risk of having a child with congenital myopathy? Because congenital myopathy is the result of a genetic change (mutation), the disorder can’t be prevented. [my.clevelandclinic.org]
A disruption in calcium ion transport prevents muscles from contracting normally, leading to the muscle weakness characteristic of multiminicore disease. RYR1 gene variants are also associated with an increased risk of malignant hyperthermia. [medlineplus.gov]
Any surgical procedure, including dental surgery, must be performed in a setting that is well monitored by anesthesiologists with necessary precautions to help prevent or appropriately manage a possible malignant hyperthermic event. [rarediseases.org]
Prevention of secondary complications: Yearly influenza and other respiratory infection-related immunizations. [ncbi.nlm.nih.gov]
