192:, with attacks often beginning in childhood. Depending on the type and severity of the HyperKPP, it can increase or stabilize until the fourth or fifth decade where attacks may cease, decline, or, depending on the type, continue on into old age. Factors that can trigger attacks include rest after exercise, potassium-rich foods, stress, fatigue, weather changes, certain pollutants (e.g., cigarette smoke) and fasting. Muscle strength often improves between attacks, although many affected people may have increasing bouts of muscle weakness as the disorder progresses (abortive attacks). Sometimes with HyperKPP those affected may experience degrees of muscle stiffness and spasms ( 270:
in a sodium leak and failure to return to the original resting membrane potential. In the presence of hyperkalemia, which causes an additional chronic depolarization of the membrane potential, this sodium leak raises the membrane potential to the point that all sodium channels, including channels produced from the wild-type allele and mutant channels that did inactivate, fail to be release from inactivation (enter depolarization block). Since the motor end plate is depolarised, further signals to contract have no effect (paralysis).

The pathological mechanism of SCN4A mutations in hyperkalemic periodic paralysis is complex, but explains the autosomal dominant and hyperkalemia-related aspects of the disease. In patients with mutations in SCN4A, not all copies of the channel inactivate following the action potential. This results

to cause contraction (tensing) of the muscle. To prevent the muscle from being perpetually contracted, the channel contains a fast inactivation gate that plugs the sodium pore very quickly after it opens. This prevents further entry of sodium. In time, potassium ions will leave the muscle cells,

Mutations altering the usual structure and function of this sodium channel therefore disrupt regulation of muscle contraction, leading to episodes of severe muscle weakness or paralysis. Mutations have been identified in residues between transmembrane domains III and IV which make up the fast
