Atrial fibrillation (AF) is a common cardiac disease and major risk factor for stroke, heart failure, and death. Tools for prediction of AF have been developed to identify individuals who might benefit from preventive therapies, incorporating conventional cardiovascular risk factors, and the effects of such risk factors have been evaluated across several cohorts.1- 2 Recently, a heritable component to AF has been reported, and polymorphisms in 3 genetic regions have been reproducibly associated with AF: chromosome 4q25, located 150 kb from the closest gene—a transcription factor (PITX2) involved in cardiac development; chromosome 16q22, intronic to another transcription factor of unknown function, expressed in cardiac tissue (ZFHX3); and an amino acid–altering variant in KCNH2, one of the major cardiac voltage-gated potassium channels.3- 5 Rare genetic variants segregating with AF are typically exclusive to individual families and unlikely to contribute to AF prediction at the population level, but genetic polymorphisms could provide important predictive information.
