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]
Dilated cardiomyopathy was present in 11% of patients. [ojrd.biomedcentral.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]
Nemaline myopathy has been described in various forms, the most severe of which presents at birth with marked weakness and hypotonia of the systemic musculature. [healio.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]

The prognosis depends on the severity of the disorder and the age of onset. [primehealthchannel.com]
Three of these patients displayed rapid clinical progression and acute respiratory insufficiency, while their prognosis was poor. [spandidos-publications.com]
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]
As such, consideration for the specific etiology is needed. Additionally, many infants/neonates with congenital myopathy can make improvements in the first few years of life. [emedicine.medscape.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]
Summary Epidemiology Annual incidence has been estimated at 1/50,000 live births in a Finnish study but the disease is more common in the Amish community. Clinical description The age of onset varies from birth to adulthood. [orpha.net]
In China, only a few NM cases were reported, and related epidemiological data have not yet become available. [spandidos-publications.com]
Epidemiology Frequency The true incidence of congenital myopathies is unknown as no large population-based studies have been conducted. However, there are a varied number of stuidies that demonstrate a relative incidence of the diseases. [emedicine.medscape.com]
Pathophysiology
This is expected to increase insight in the role of the KBTBD13 gene in the pathophysiology of this myopathy. [healthacademy.radboudumc.nl]
