Herg mutation
Witryna23 mar 2024 · Drug-induced cardiotoxicity represents one of the most critical safety concerns in the early stages of drug development. The blockade of the human ether-à-go-go-related potassium channel (hERG) is the most frequent cause of cardiotoxicity, as it is associated to long QT syndrome which can lead to fatal arrhythmias. Therefore, … Witryna2 lip 2024 · Congenital long QT syndrome (LQTS) is a heart channel disease associated with fatal ventricular arrhythmias or cardiac arrest. Human ether-a-go-go-related gene …

Mutations in the human ether-a-go-go-related gene (HERG)1 cause LQT, an inherited disorder of cardiac repolarization (1– 10). HERG encodes a potassium channel with properties nearly identical to I Kr of cardiac myocytes (11, 12). Mutations in HERG can reduce I Kr by loss of function, altered function, or a
WitrynaBiochemical and detailed structural information of human ether-a-go-go-related gene (hERG) potassium channels are scarce but a prerequisite to understand the unwanted interactions of hERG with drugs and the effect of mutations that lead to the long QT syndrome. Despite the huge interest in hERG, to our knowledge, procedures that … hERG (the human Ether-à-go-go-Related Gene) is a gene that codes for a protein known as K v 11.1, the alpha subunit of a potassium ion channel. ... either by application of drugs or by rare mutations in some families, it can result in a potentially fatal disorder called long QT syndrome. Zobacz więcej hERG (the human Ether-à-go-go-Related Gene) is a gene (KCNH2) that codes for a protein known as Kv11.1, the alpha subunit of a potassium ion channel.
