Chrne congenital myasthenia
WebCongenital myasthenic syndromes (CMS) result from a variety of mutations affecting the neuromuscular junction and are characterized by fatigability and weakness of different muscle groups, commonly including the ocular muscles. CMS is diagnosed via a combination of clinical findings and genetic testing. WebChevessier et al. (2004) reported a 27-year-old French woman with congenital myasthenic syndrome. Her similarly affected brother died at 1.5 years of age. Muscle biopsy showed dramatic pre- and postsynaptic structural abnormalities of the NMJ and severe decreases in CHRNE and MUSK expression.Mihaylova et al. (2009) reported 5 sibs, born of …

The AChR protein is found in the membrane … WebAmong 5 Dutch patients with congenital myasthenic syndrome associated with AChR deficiency, Ealing et al. (2002) identified 4 mutations in the CHRNE gene. The mutations were located in the 18-amino acid epsilon subunit C terminus, which lies extracellular to the M4 transmembrane domain of the AChR.
WebMyotonia congenita is an inherited/familial disorder in goats and Shropshire lambs and is occasionally seen in horses. It causes muscle rigidity; marked dimpling on percussion of the muscle belly; and a stiff, stilted gait. Electromyography is a useful aid to diagnosis. This disease results from a mutation in a chloride channel (CLCN1). WebAbstract Background: Congenital myasthenic syndromes (CMSs) are a heterogeneous group of neuromuscular disorders. Mutations of the nicotinic acetylcholine receptor epsilon subunit gene (CHRNE) are the most common causes of these disorders. CMSs are gaining increasing recognition by clinicians.
