- Genome-wide association studies of cardiac electrical phenotypes
Final published version, 855 KB, PDF document
The genetic basis of cardiac electrical phenotypes has in the last twenty-five years been the subject of intense investigation. While in the first years, such efforts were dominated by the study of familial arrhythmia syndromes, in recent years large consortia of investigators have successfully pursued genome-wide association studies (GWAS) for the identification of single nucleotide polymorphisms that govern interindividual variability in electrocardiographic parameters in the general population. We here provide a review of GWAS conducted on cardiac electrical phenotypes in the last 14 years and discuss the implications of these discoveries for our understanding of the genetic basis of disease susceptibility and variability in disease severity. Furthermore, we review functional follow-up studies that have been conducted on GWAS loci associated with cardiac electrical phenotypes and highlight the challenges and opportunities offered by such studies.
