Dear Editor, Loss-of-function and gain-of-function mutations in the KCNH2 gene cause long and short-QT syndromes (LQTS or SQTS), respectively, predisposing to life-threatening F I G U R E 1 Repolarization power of wild-type (WT) hERG as a function of temperature. A simplified and optimized action potential was applied (AP-clamp) by an automated...

Background and aims: Mutations in KCNH2 cause long or short QT syndromes (LQTS or SQTS) predisposing to life-threatening arrhythmias. Over 1000 hERG variants have been described by clinicians, but most remain to be characterised. The objective is to standardise and accelerate the phenotyping process to contribute to clinician diagnosis and...
