NINDS:45 Lambert-Eaton myasthenic syndrome (LEMS) is a disorder of the neuromuscular junction-the site where nerve cells meet muscle cells and help activate the muscles. It is caused by a disruption of electrical impulses between these nerve and muscle cells. LEMS is an autoimmune condition; in such disorders the immune system, which normally protects the body from foreign organisms, mistakenly attacks the body's own tissues. The disruption of electrical impulses is associated with antibodies produced as a consequence of this autoimmunity. Symptoms include muscle weakness, a tingling sensation in the affected areas, fatigue, and dry mouth. LEMS is closely associated with cancer, in particular small cell lung cancer. More than half the individuals diagnosed with LEMS also develop small cell lung cancer. LEMS may appear up to 3 years before cancer is diagnosed.

MalaCards: Lambert-Eaton Myasthenic Syndrome, also known as myasthenic-myopathic syndrome of lambert-eaton, is related to lambert syndrome and lung cancer. An important gene associated with Lambert-Eaton Myasthenic Syndrome is CACNB2 (calcium channel, voltage-dependent, beta 2 subunit), and among its related pathways are ADP signalling through P2Y purinoceptor 12 and Integration of energy metabolism. The compounds nimodipine and nitrendipine have been mentioned in the context of this disorder. Affiliated tissues include lung, cerebellum and skeletal muscle, and related mouse phenotypes are respiratory system and craniofacial.

Disease Ontology:9 A neuromuscular junction disease that results from an abnormality of acetylcholine (ach) release at the neuromuscular junction. it results from an autoimmune attack against voltage-gated calcium channels (vgcc) on the presynaptic motor nerve terminal.

NIH Rare Diseases:44 Lambert eaton myasthenic syndrome (lems) is a disorder of the neuromuscular junction. the neuromuscular junction is the site where nerve cells meet muscle cells and help activate the muscles. this syndrome occurs when antibodies interfere with electrical impulses between the nerve and muscle cells. it may be associated with other autoimmune diseases, or more commonly coincide with or precede a diagnosis of cancer such as small cell lung cancer. symptoms may include muscle weakness, a tingling sensation in the affected areas, fatigue, and dry mouth. treatment of a underlying disorder or cancer is the first priority of treatment. last updated: 4/22/2011
