A C‐terminal skeletal muscle sodium channel mutation associated with myotonia disrupts fast inactivation

18 Mar 2005

Abstract excerpt

Missense mutations in the skeletal muscle sodium channel alpha-subunit gene (SCN4A) are associated with a group of clinically overlapping diseases caused by alterations in the excitability of the sarcolemma. Sodium channel defects may increase excitability and cause myotonic stiffness or may render fibres transiently inexcitable to produce periodic paralysis. A patient with cold-aggravated myotonia did not...
