A Missense Variant in PLEC Increases Risk of Atrial Fibrillation

Genome-wide association studies (GWAS) have yielded variants at >30 loci that associate with atrial fibrillation (AF), including rare coding mutations in the sarcomere genes MYH6 and MYL4. The aim of this study was to search for novel AF associations and in doing so gain insights into the mechanisms whereby variants affect AF risk, using electrocardiogram (ECG) measurements. The authors performed a GWAS of 14,255 AF cases and 374,939 controls,...
