We conclude that a higher PRS of SNVs rs3807989 (CAV1), rs11047543 (SOX5), rs28631169 (MYH7), rs2106261 (ZFHX3), rs13376333 (KCNN3), rs75190942 (KCNJ5), rs2200733 (PITX2) and rs6838973 (PITX2) is likely associated with increased odds of AF recurrence after successful sinus rhythm restoration with DCC. The gene discussed is KCNN3; the disease is atrial fibrillation.
