NKX2-5 and atrial fibrillation: NKX2-5 (TF), H3K27ac, and ATAC peaks are associated with enrichment for EKG characteristics such as heart rate, QT interval, QRS duration, and atrial fibrillation. Histone acetylation and TF info from ChIP-seq can be cross-referenced with ATAC-seq peaks and GWAS to illuminate mechanisms of phenotypic effects. dbGaP: phs000924; NCBI: PRJNA285375; GEO: GSE125540, GSE133833 [155].
