  1. The hap-ASM data are from our published study [49], with confirmation by additional unpublished Methyl-seq data (CD and BT; unpublished data). Of these nine loci, six were also covered and found to have ASM or mQTLs in one or more cell types by Cheung et al. [53]. Regulome-DB scores for the hap-ASM index SNPs are from RegulomeDB (http://www.regulomedb.org/). The scores ranged from 1a to 6, with 1 assigned to putative regulatory SNPs with the highest level of confidence, supported by multiple data types, including eQTLs, TF binding, TF motifs, DNAse footprints, and DNAse hypersensitivity peaks [20]. Cis-eQTLs were downloaded from National Heart, Lung and Blood Institute (NHLBI)-GRASP Build 2.0 [46], only genes with eQTL p value <10−05 are listed. Haplotype blocks were defined using 1000 Genomes project (phase 3) [182] and PLINK (Gabriel’s approach) data [183, 184]. The S100A* cluster includes: S100A4; S100A3; S100A2; S100A16; S100A14; S100A13; and S100A1. The HIST1H* cluster includes: HIST1H1D; HIST1H4F; HIST1H4G; HIST1H3F; HIST1H2BH; HIST1H3G; HIST1H2BI; and HIST1H4H. The TRIM* cluster includes: TRIM10; TRIM15; and TRIM26. Multiple eQTLs have been identified in the haplotype blocks; in the eight first examples, at least one of the eQTLs was also an ASM index SNP, suggesting that these SNPs are regulatory SNPs
  2. aIndex eQTL reported in NHLBI-GRASP is rs6926079, in the same haplotype block as rs62396301 (R2 = 0.975, D′ = 1)
