Summaries for Thyrotoxic Periodic Paralysis 2

UniProtKB/Swiss-Prot : 75 Thyrotoxic periodic paralysis 2: A sporadic muscular disorder characterized by episodic weakness and hypokalemia during a thyrotoxic state. It is clinically similar to hereditary hypokalemic periodic paralysis, except for the fact that hyperthyroidism is an absolute requirement for disease manifestation. The disease presents with recurrent episodes of acute muscular weakness of the four extremities that vary in severity from paresis to complete paralysis. Attacks are triggered by ingestion of a high carbohydrate load or strenuous physical activity followed by a period of rest. Thyrotoxic periodic paralysis can occur in association with any cause of hyperthyroidism, but is most commonly associated with Graves disease.

MalaCards based summary : Thyrotoxic Periodic Paralysis 2, also known as thyrotoxic periodic paralysis, susceptibility to, 2, is related to thyrotoxic periodic paralysis and thyrotoxic periodic paralysis 1. An important gene associated with Thyrotoxic Periodic Paralysis 2 is KCNJ18 (Potassium Voltage-Gated Channel Subfamily J Member 18). Affiliated tissues include thyroid and colon, and related phenotypes are muscle weakness and hypokalemia
