Table 2. Breakdown of ASB SNVs in each ethnic population.

ACC, accessible; ASB, allele-specific binding; CEU, Utah residents in the United States with Northern and Western European ancestry; CHB, Han Chinese from Beijing, China; HET, heterozygous; JPT, Japanese from Tokyo, Japan; MAF, minor allele frequency; SNV, single nucleotide variant; TF, transcription factor; YRI, Yorubans from Ibadan, Nigeria.

HET, ACC and ASB SNVs with MAF are shown for 381 unrelated individuals (excluding NA12878). For each of the last 3 columns, each category of HET, ACC and allele-specific SNVs is further stratified by the population MAFs: common (MAF>0.05), rare (MAF≤0.01) and very rare (MAF≤0.005). The number of allele-specific SNVs is given as a percentage of the ACC SNVs.

This table also provides the number of individuals from each ethnic population with ChIP-seq data available for the ASB analyses.
