Summaries for Congenital Myasthenic Syndrome

NIH Rare Diseases : 50 congenital myasthenic syndrome (cms) is a group of genetic disorders that result in muscle weakness and fatigue. symptoms can range from mild weakness to progressive disabling weakness. there are three main subtypes of cms, which are defined by how they affect the connection between muscles and the nervous system: postsynaptic (75-80% of patients), synaptic (14-15% of patients), and presynaptic (7-8% of patients). identification of the specific subtype is important in patient care for determining the most effective treatment. mutations in many genes have been found to cause cms, and most forms of cms are inherited in an autosomal recessive pattern. one form of cms, a postsynaptic form known as slow-channel syndrome congenital myasthenic syndrome is inherited in an autosomal dominant manner. last updated: 7/10/2013

MalaCards based summary : Congenital Myasthenic Syndrome, also known as congenital myasthenia, is related to congenital myasthenic syndrome 20 and congenital myasthenic syndrome 21, and has symptoms including facial paresis An important gene associated with Congenital Myasthenic Syndrome is SCN4A (Sodium Voltage-Gated Channel Alpha Subunit 4), and among its related pathways/superpathways are Synthesis of substrates in N-glycan biosythesis and Activation of Nicotinic Acetylcholine Receptors. The drugs 4-Aminopyridine and Potassium Channel Blockers have been mentioned in the context of this disorder. Affiliated tissues include eye and skeletal muscle, and related phenotypes are mortality/aging and behavior/neurological

Disease Ontology : 12 A neuromuscular junction disease that is characterized by weakness and easy fatiguability resulting from a genetic defect at the junction where the nerve stimulates muscle activity that result in muscle weakness and may affect nerve cells (presynaptic), muscle cells (postsynaptic) or the space between nerve and muscle cells (synaptic).

Genetics Home Reference : 25 Congenital myasthenic syndrome is a group of conditions characterized by muscle weakness (myasthenia) that worsens with physical exertion. The muscle weakness typically begins in early childhood but can also appear in adolescence or adulthood. Facial muscles, including muscles that control the eyelids, muscles that move the eyes, and muscles used for chewing and swallowing, are most commonly affected. However, any of the muscles used for movement (skeletal muscles) can be affected in this condition. Due to muscle weakness, affected infants may have feeding difficulties. Development of motor skills such as crawling or walking may be delayed. The severity of the myasthenia varies greatly, with some people experiencing minor weakness and others having such severe weakness that they are unable to walk.

NINDS : 51 All forms of myasthenia are due to problems in the communication between nerve cells and muscles. Most involve the activities of neurotransmitters. Neurotransmitters are chemicals that allow neurons to relay information from one cell to the next. For neurotransmitters to be effective, the nerve cell must release the neurotransmitter properly, and the muscle cell must be able to detect the neurotransmitter and respond to its signal properly.
