Summaries for Periodic Paralyses

NINDS : 50 Familial periodic paralyses are a group of inherited neurological disorders caused by mutations in genes that regulate sodium and calcium channels in nerve cells. They are characterized by episodes in which the affected muscles become slack, weak, and unable to contract. Between attacks, the affected muscles usually work as normal. The two most common types of periodic paralyses are:Hypokalemic periodic paralysis is characterized by a fall in potassium levels in the blood. In individuals with this mutation attacks often begin in adolescence and are triggered by strenuous exercise, high carbohydrate meals, or by injection of insulin, glucose, or epinephrine. Weakness may be mild and limited to certain muscle groups, or more severe and affect the arms and legs. Attacks may last for a few hours or persist for several days. Some patients may develop chronic muscle weakness later in life.Hyperkalemic periodic paralysis is characterized by a rise in potassium levels in the blood. Attacks often begin in infancy or early childhood and are precipitated by rest after exercise or by fasting. Attacks are usually shorter, more frequent, and less severe than the hypokalemic form. Muscle spasms are common.

MalaCards based summary : Periodic Paralyses is related to malignant hyperthermia and familial periodic paralyses. An important gene associated with Periodic Paralyses is SCN4A (Sodium Voltage-Gated Channel Alpha Subunit 4), and among its related pathways/superpathways are Cardiac conduction and Dopamine-DARPP32 Feedback onto cAMP Pathway. The drugs Lamotrigine and Dichlorphenamide have been mentioned in the context of this disorder. Affiliated tissues include skeletal muscle, and related phenotypes are shRNA abundance <= 50% and digestive/alimentary
