NCOR2 and atrial fibrillation: Interestingly, we found loci not previously described in AF or CES with four prioritized genes, namely, TMEM60, KIAA1755, NCOR2, and FILIP1. Functional annotation of the index SNVs revealed rs3746471 as a missense variant of the KIAA1755 gene coding for R1045W, and it was predicted to be deleterious with a SIFT score of 0.007.
