Summaries for Normokalemic Periodic Paralysis

NIH Rare Diseases : 53 Normokalemic periodic paralysis (NormoKPP) is an inherited muscle disorder characterized by episodic attacks of muscle weakness. It was initially considered a distinct condition, but most physicians now consider it to be a variant form of hyperkalemic periodic paralysis. People with hyperkalemic periodic paralysis have increased potassium levels during an attack; people with the normokalemic form do not experience any change in their potassium levels during weakness, but most grow weak when given potassium. Studies have shown that both forms of the condition are caused by mutations in the SCN4A gene and it is inherited in an autosomal dominant manner. The goals of treatment are to relieve acute symptoms and prevent further attacks.

MalaCards based summary : Normokalemic Periodic Paralysis, also known as normokalemic periodic paralysis, potassium-sensitive, is related to hyperkalemic periodic paralysis and lipoid congenital adrenal hyperplasia. An important gene associated with Normokalemic Periodic Paralysis is SCN4A (Sodium Voltage-Gated Channel Alpha Subunit 4), and among its related pathways/superpathways are Cardiac conduction and Neuropathic Pain-Signaling in Dorsal Horn Neurons. Affiliated tissues include tongue and skeletal muscle, and related phenotypes are abnormality of metabolism/homeostasis and abnormality of the tongue
