Familial Periodic Paralysis (C0030443)

Definition (NCI) A group of genetic neurological disorders caused by mutations in genes involved in the sodium and calcium channels in nerve cells. It is characterized by episodes of muscle paralysis in which the affected muscles become flaccid and the deep tendon reflexes disappear. Between the episodes the affected muscles usually work normally.
Definition (MSH) A heterogenous group of inherited disorders characterized by recurring attacks of rapidly progressive flaccid paralysis or myotonia. These conditions have in common a mutation of the gene encoding the alpha subunit of the sodium channel in skeletal muscle. They are frequently associated with fluctuations in serum potassium levels. Periodic paralysis may also occur as a non-familial process secondary to THYROTOXICOSIS and other conditions. (From Adams et al., Principles of Neurology, 6th ed, p1481)

Hypokalemic periodic paralysis (C0238358)

Definition (NCI) An autosomal dominant inherited or genetic disorder characterized by irregular episodes of muscle weakness or paralysis which are always accompanied by low levels of potassium in the blood.
Definition (MSH) An autosomal dominant familial disorder characterized by recurrent episodes of skeletal muscle weakness associated with falls in serum potassium levels. The condition usually presents in the first or second decade of life with attacks of trunk and leg paresis during sleep or shortly after awakening. Symptoms may persist for hours to days and generally are precipitated by exercise or a meal high in carbohydrates. (Adams et al., Principles of Neurology, 6th ed, p1483)
