Nemaline myopathy is a disorder that primarily affects skeletal muscles, which are muscles that the body uses for movement. People with nemaline myopathy have muscle weakness (myopathy) throughout the body, but it is typically most severe in the muscles of the face; neck; trunk; and other muscles close to the center of the body (proximal muscles), such as those of the upper arms and legs. This weakness can worsen over time. Affected individuals may have feeding and swallowing difficulties, foot deformities, abnormal curvature of the spine (scoliosis), and joint deformities (contractures). Most people with nemaline myopathy are able to walk, although some affected children may begin walking later than usual. As the condition progresses, some people may require wheelchair assistance. In severe cases, the muscles used for breathing are affected and life-threatening breathing difficulties can occur.
Nemaline myopathy is divided into six types. In order of decreasing severity, the types are: severe congenital, Amish, intermediate congenital, typical congenital, childhood-onset, and adult-onset. The types are distinguished by the age when symptoms first appear and the severity of symptoms; however, there is overlap among the various types. The severe congenital type is the most life-threatening. Most individuals with this type do not survive past early childhood due to respiratory failure. The Amish type solely affects the Old Order Amish population of Pennsylvania and is typically fatal in early childhood. The most common type of nemaline myopathy is the typical congenital type, which is characterized by muscle weakness and feeding problems beginning in infancy. Most of these individuals do not have severe breathing problems and can walk unassisted. People with the childhood-onset type usually develop muscle weakness in adolescence. The adult-onset type is the mildest of all the various types. People with this type usually develop muscle weakness between ages 20 and 50.
MalaCards based summary : Nemaline Myopathy, also known as rod myopathy, is related to nemaline myopathy 3 and nemaline myopathy 2. An important gene associated with Nemaline Myopathy is NEB (Nebulin), and among its related pathways/superpathways are Cardiac muscle contraction and Axon guidance. The drug Tyrosine has been mentioned in the context of this disorder. Affiliated tissues include skeletal muscle, heart and testes. Disease Ontology : 12 A congenital structural myopathy characterized by generally non-progressive muscle weakness of varying severity; certain muscle fibers show the presence of rod-like structures called nemaline bodies. NIH Rare Diseases : 52 Nemaline myopathy is a disorder that primarily affects skeletal muscles, which are muscles that the body uses for movement. People with nemaline myopathy have muscle weakness (myopathy) throughout the body, but it is typically most severe in the muscles of the face, neck, and limbs. This weakness can worsen over time. Affected individuals may have feeding and swallowing difficulties, foot deformities, abnormal curvature of the spine (scoliosis ), and joint deformities (contractures ). Mutations in at least six genes can cause nemaline myopathy. Some individuals with nemaline myopathy do not have an identified mutation. The genetic cause of the disorder is unknown in these individuals. Nemaline myopathy is usually inherited in an autosomal recessive pattern. Less often, this condition is inherited in an autosomal dominant pattern. Nemaline myopathy is divided into six types. You can search for information about a particular type of nemaline myopathy from the GARD Home page . Enter the name of the condition in the GARD search box and then select the type from the drop down menu. KEGG : 36 Nemaline myopathy (NM) is the most common congenital myopathy inherited in an autosomal dominant or autosomal recessive manner. It is characterized by the presence of rods or nemaline bodies, which are red-purple inclusions in myofibers detected by modified Gomori trichrome technique. The hallmark symptoms are generalized muscle weakness with facial involvement or predominant involvement of proximal limb and respiratory muscles. Currently, NM is classified into six different forms: severe congenital (neonatal) form; Amish NM, intermediate congenital form; typical congenital form; childhood-onset form; and adult-onset (late-onset) form. Mutations in several genes, encoding components of the sarcomeric thin filaments, have been identified. Mutations in ACTA1 and NEB nebulin are the most common.
