Benign congenital myopathy with myasthenic features.
It has been increasingly apparent in recent years that in addition to cases which fall into recognizable categories of muscle disease, a number of less common disorders occur from time to time which do not correspond to the accepted descriptions. Some of these appear to be metabolic in origin and can be elucidated, at least in part, by modern methods of investigation (McArdle, 1951) while other...
متن کاملCongenital myasthenic syndromes.
Congenital myasthenic syndromes are a rare group of heterogeneous disorders affecting neuromuscular transmission. Recent identification and in-vitro functional analysis of some of the genetic mutations that cause these disorders correlates with previous electrophysiological, biochemical, pathological and therapeutic studies, and has advanced our understanding of neuromuscular transmission.
متن کاملCongenital myasthenic syndromes.
PURPOSE OF REVIEW Congenital myasthenic syndromes are a heterogeneous group of diseases caused by genetic defects affecting neuromuscular transmission. In this article, a strategy that leads to the diagnosis of congenital myasthenic syndromes is presented, and recent advances in the clinical, genetic and molecular aspects of congenital myasthenic syndrome are outlined. RECENT FINDINGS Besides...
متن کاملCongenital myopathy with cytoplasmic bodies.
Since early infancy, a 15-year-old girl had suffered from an apparently static neuromuscular disorder that chiefly afflicted her proximal muscles but did not spare her distal ones. Her CPK values had repeatedly been mildly elevated and her electromyogram had been considered "myopathic". There were no similar neuromuscular disorders in the family. Quadriceps muscle biopsy showed a type I myofibe...
متن کاملcongenital myasthenic syndromes
congenital myasthenic syndromes (cms) are a group of diseases caused by genetic defects affecting neuromuscular transmission and are heterogeneous in inheritance and pathophysiology. these are classified as: 1. presynaptic defects: including choline acetyl transferase deficiency, paucity of synaptic vesicles, lambert-eaton like cms 2. synaptic defect: endplate ach esterase deficiency 3. postsyn...
