Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder.The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles and rigidity. [1]
Myotonia is the defining symptom of many channelopathies (diseases of ion channel transport) such as myotonia congenita, paramyotonia congenita and myotonic dystrophy. [3] [4] Brody disease (a disease of ion pump transport) has symptoms similar to myotonia congenita, however, the delayed muscle relaxation is pseudo-myotonia as the EMG is normal ...
NMT is a diverse disorder. As a result of muscular hyperactivity, patients may present with muscle cramps, stiffness, myotonia-like symptoms (slow relaxation), associated walking difficulties, hyperhidrosis (excessive sweating), myokymia (quivering of a muscle), fasciculations (muscle twitching), fatigue, exercise intolerance, myoclonic jerks and other related symptoms.
Mutations in this gene cause two forms of inherited human muscle disorders: recessive generalized myotonia congenita (Becker) and dominant myotonia (Thomsen). [ 5 ] Chloride channel protein, skeletal muscle ( CLCN1 ) is a protein that in humans is encoded by the CLCN1 gene . [ 6 ]
Potassium-aggravated myotonia is a rare genetic disorder that affects skeletal muscle. [2] Beginning in childhood or adolescence, people with this condition experience bouts of sustained muscle tensing ( myotonia ) that prevent muscles from relaxing normally.
Isolated case reports of myotonia had been published previously, including reports by Frederick Eustace Batten and Hans Curschmann, and type 1 myotonic dystrophy is therefore sometimes known as Curschmann-Batten-Steinert syndrome. [35] The underlying cause of type 1 myotonic dystrophy was determined in 1992. [2]
Both universities are expected to increase the biomedical research.Recently, the school has taken ownership of three new research facilities over the past year for a total of over 80,000 square feet of dedicated biomedical engineering research and teaching space at both Virginia Tech and Wake Forest University.
Bethlem myopathy is predominantly an autosomal dominant myopathy, classified as a congenital form of limb-girdle muscular dystrophy. [2] There are two types of Bethlem myopathy, based on which type of collagen is affected.
