Black individuals with a genetic mutation found to have increased risk of developing atrial fibrillation, heart failure

Physician–scientists from the University of Alabama at Birmingham Marnix E. Heersink School of Medicine led a nationwide genetic study examining the role of genetic mutations in the Titin, TTN, gene in Black individuals. In their study, published in Nature Cardiovascular Research they found that Black individuals carrying these genetic variants were at a high risk of developing atrial fibrillation and heart failure.
