Descriptor síndrome de Andersen
Scope note: Forma de síndrome de QT largo hereditario (o LQT7) que se caracteriza por una tríada de parálisis periódica sensible al potasio, LATIDOS VENTRICULARES ECTÓPICOS y rasgos anormales como estatura corta, pabellones auriculares de implantación baja y ESCOLIOSIS. Es consecuencia de mutaciones del gen KCNJ2 que codifica una proteína del canal (CANALES DEL POTASIO RECTIFICADORES DE ENTRADA) que regula el potencial de membrana en reposo.

Scope note: A form of inherited long QT syndrome (or LQT7) that is characterized by a triad of potassium-sensitive periodic paralysis, VENTRICULAR ECTOPIC BEATS, and abnormal features such as short stature, low-set ears, and SCOLIOSIS. It results from mutations of KCNJ2 gene which encodes a channel protein (INWARD RECTIFIER POTASSIUM CHANNELS) that regulates resting membrane potential.
