Description

Principal Investigator: Dan Roden, MD, Vanderbilt University Medical Center, Nashville, TN, USA MeSH: Long QT Syndrome,Torsades de Pointes https://www.ncbi.nlm.nih.gov/projects/gap/cgi-bin/study.cgi?study_id=phs000331 The goal of this study was to identify genetic risk factors for drug-induced prolongation of the QT interval (diLQT) and the ventricular arrhythmia torsades de pointes (TdP). We conducted a genome-wide association study (GWAS) focusing on subjects with a history of long QT and/or TdP after taking medication. Controls for this study were individuals with a history of cardiac arrhythmias who had begun treatment with potentially QT-prolonging antiarrhythmics. An additional control group of normal volunteers were given ibutilide, a drug with documented proarrhythmic properties. All study participants were recruited and treated/evaluated at Vanderbilt University Medical Center. This study was conducted by the Pharmacogenomics of Arrhythmia Therapy subgroup of the Pharmacogenetics Research Network, a nationwide collaboration of scientists studying the genetic contributions to drug response variability. Genotyping was performed by the RIKEN research institute in Japan using the Illumina 610 Quad Beadchip platform.
