Summaries for Hyperkalemic Periodic Paralysis

NIH Rare Diseases : 54 Hyperkalemic periodic paralysis is a genetic disease that causes episodes of extreme muscle weakness and an increase of the potassium levels in the blood. Muscle weakness during an attack usually affects the arms and legs and muscles of the eyes, throat, and trunk. Most often, these episodes involve a temporary inability to move muscles in the arms and legs. Episodes usually begin before age 20, usually between infancy and age 10. Normally an episode lasts for 15 minutes to an hour, but in some people the episodes may last a few days to a week. Episodes tend to increase in frequency until about age 50, after which they may occur less frequently. Factors that can trigger attacks include rest after strenuous exercise, potassium-rich foods, stress, fatigue, and exposure to cold. Depolarizing anesthetics should also be avoided. Muscle strength usually returns to normal between episodes, although many people continue to experience mild stiffness, particularly in muscles of the face and hands. Studies suggest more than 80% of people with hyperkalemic periodic paralysis over age 40 have permanent muscle weakness, most often affecting the leg muscles. About one third may develop a chronic progressive myopathy.  Hyperkalemic periodic paralysis is caused by mutations in the SCN4A gene and is inherited in an autosomal dominant manner. Diagnosis is based on clinical symptoms including the increase of blood potassium level during an episode, but normal levels of blood potassium level in between episodes. Genetic testing can confirm the diagnosis. Treatment is focused on avoiding triggers and decreasing the severity of an episode. At the first sign of muscle weakness, episodes in many people may be prevented or stopped by mild exercise and/or eating carbohydrates, inhalation of salbutamol, or intravenous calcium gluconate.

MalaCards based summary : Hyperkalemic Periodic Paralysis, also known as familial hyperkalemic periodic paralysis, is related to hypokalemic periodic paralysis, type 1 and myotonia, and has symptoms including myalgia, stridor and muscular stiffness. An important gene associated with Hyperkalemic Periodic Paralysis is SCN4A (Sodium Voltage-Gated Channel Alpha Subunit 4), and among its related pathways/superpathways are Activation of cAMP-Dependent PKA and Cardiac conduction. The drugs Hops and Dichlorphenamide have been mentioned in the context of this disorder. Affiliated tissues include testes, eye and skeletal muscle, and related phenotypes are emg abnormality and reduced tendon reflexes

Genetics Home Reference : 26 Hyperkalemic periodic paralysis is a condition that causes episodes of extreme muscle weakness or paralysis, usually beginning in infancy or early childhood. Most often, these episodes involve a temporary inability to move muscles in the arms and legs. Episodes tend to increase in frequency until mid-adulthood, after which they occur less frequently in many people with the condition. Factors that can trigger attacks include rest after exercise, potassium-rich foods such as bananas and potatoes, stress, fatigue, alcohol, pregnancy, exposure to hot or cold temperatures, certain medications, and periods without food (fasting). Muscle strength usually returns to normal between attacks, although many affected people continue to experience mild stiffness (myotonia), particularly in muscles of the face and hands.

OMIM : 58 The 2 dominantly inherited, clinically similar types of episodic flaccid generalized weakness, HOKPP and HYPP, are distinguished by the changes in serum potassium levels during paralytic attacks. An important clinical difference between the 2 entities is represented by the triggers of attacks of weakness, e.g., HYPP can be provoked by oral potassium administration, whereas this is a remedy for HOKPP. Concurrence of myotonia is found in HYPP but usually not in HOKPP patients (Jurkat-Rott et al., 2000). Jurkatt-Rott and Lehmann-Horn (2007) provided a review of the clinical features, pathogenesis, and therapeutic options for HYPP. (170500)

UniProtKB/Swiss-Prot : 76 Periodic paralysis hyperkalemic: An autosomal dominant channelopathy characterized by episodic flaccid generalized muscle weakness associated with high levels of serum potassium. Concurrence of myotonia is found in HYPP patients. Periodic paralysis normokalemic: A disorder closely related to hyperkalemic periodic paralysis, but marked by a lack of alterations in potassium levels during attacks of muscle weakness.
