Andersen-Tawil Syndrome

Edit

This entry is adapted from the peer-reviewed paper https://medlineplus.gov/genetics/condition/andersen-tawil-syndrome

Andersen-Tawil syndrome is a disorder that causes episodes of muscle weakness (periodic paralysis), changes in heart rhythm (arrhythmia), and developmental abnormalities. Periodic paralysis begins early in life, and episodes last from hours to days. These episodes may occur after exercise or long periods of rest, but they often have no obvious trigger. Muscle strength usually returns to normal between episodes. However, mild muscle weakness may eventually become permanent.
