Cold-induced disruption of Na(+) channel slow inactivation underlies paralysis in highly thermosensitive paramyotonia

The Q270K mutation of the skeletal muscle Na(+) channel α subunit (Nav1.4) causes atypical paramyotonia with a striking sensitivity to cold. Attacks of paralysis and a drop in the compound muscle action potential (CMAP) are exclusively observed at cold. To understand the pathogenic process, we studi...
