TF and B-cell chronic lymphocytic leukemia: In the absence of comprehensive TF chromatin immunoprecipitation sequencing (ChIP-Seq) data from CLL samples, we used regions of chromatin accessibility defined by ATAC-seq data19 as a surrogate marker for TF binding, identifying 47 SNPs in LD r2>0.2 with the sentinel SNPs that also overlapped ATAC-seq peaks.
