Abstract:
Andersen-Tawil syndrome (ATS) is one of the periodic paralyses, a set of skeletal muscle disorders that cause transient weakness of the arms and legs lasting minutes to many hours. Distinguishing features of ATS include facial and limb dysmorphisms, cardiac arrhythmia, difficulties with executive function, and association with dominant mutations in the potassium channel, KCNJ2. In this review, we discuss the key features of ATS, diagnostic testing, pathophysiology and treatment of ATS, and compare them with other periodic paralyses.

These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Pleiotropy
Smooth Endoplasmic Reticulum
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
