A Common SCN5A Variant Is Associated with PR Interval and Atrial Fibrillation Among African Americans
rs7629265 and AF Risk ObjectiveWe examined the association of rs7626962 (S1103Y) or rs7629265, a variant in high linkage disequilibrium with S1103Y (r(2) = 0.87 - 1), with sudden cardiac death (SCD) and atrial fibrillation (AF) among African Americans. BackgroundThe SCN5A missense variant S1103Y has been associated with SCD among African Americans in small case-control studies, but larger populati
