Presentation
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]
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]
Dilated cardiomyopathy was present in 11% of patients. [ojrd.biomedcentral.com]
Documentation: A patient with congenital nemaline myopathy may present at any age with clinical findings associated with the severity of muscle disease. [meducator3.net]

Workup
Look out for: scoliosis, kyphosis, cronic ear infections (tubes often needed) Recommended: annual sleep study, swallow study/study of aspiration, nutritionist workup, cranial/facial follow-up, endocrine work-up, baseline cardiologist work-up and follow-up [nemaline.org]
Thus, SYCP3 testing may be considered in the workup for women with recurrent pregnancy loss, and in males with non-obstructive azoospermia. Our laboratory offers DNA sequencing of all coding exons (2-9) of the SYCP3 gene. [chginc.org]
Treatment
Chest physical therapy, antibiotics, inhalation treatments, and enriched diets are few of many treatment options. Return to the top of this page. [kveller.com]
Stem cell therapy is being considered as a possible treatment option for adult-onset NM as some patients have responded well to this treatment. [primehealthchannel.com]
No proven effective therapy other than symptomatic treatment Symptomatic treatment has shown to be helpful in many patients ( Semin Pediatr Neurol 2011;18:230 ) Mechanical nighttime ventilation Orthoses Nasogastric feeding and nutritional support Aggressive [pathologyoutlines.com]
Management and treatment A multidisciplinary approach is needed to handle respiratory insufficiency (permanent or intermittent use of mechanical ventilation and treatment of lower respiratory tract infections) and feeding difficulties (feeding techniques [orpha.net]
Prognosis
Prognosis Prognosis depends on the NM type, and life expectancy ranges from few months to a near-normal lifespan. The documents contained in this web site are presented for information purposes only. [orpha.net]
Prognosis - Nemaline myopathy 6 Not supplied. Treatment - Nemaline myopathy 6 Not supplied. Resources - Nemaline myopathy 6 Not supplied. [checkorphan.org]
The prognosis depends on the severity of the disorder and the age of onset. [primehealthchannel.com]
Fetal NM is a severe form of NM that carries a poor prognosis. [frontiersin.org]
Etiology
Adult-onset NM is usually sporadic ( Etiology Seven genes involved in muscle thin filament structure and function, have been linked to NM: NEB (2q22), TPM2 (9p13), TPM3 (1q21.2), ACTA1 (1q42.13), TNNT1 (19q13.4), CFL2 (14q12) and KBTBD13 (15q22.31). [orpha.net]
Nemaline rods are seen as a minor feature of muscle biopsies in a variety of neuromuscular disorders 10 and rarely even in normal muscle. 8 Nemaline myopathy is diagnosed when nemaline rods are the predominant finding 8 and features of other etiologies [jamanetwork.com]

Nemaline Myopathy Causes The exact etiology of this condition is still not known. Researchers have shown certain genetic mutations to be responsible for its occurrence. [primehealthchannel.com]
Epidemiology
Epidemiological rarity and nosographic controversy of CM have contributed to this lack of molecular genetic progress in CM. View full text Copyright © 1996 Published by Elsevier Inc. [sciencedirect.com]
