Definition of AS-SNPs at a population level. ChIP-seq reads were aligned to personalized genomes for each cell line and summed across cell lines at heterozygous positions. The resulting allele specific read count was tested for statistical significance to identify AS-SNPs defined at a population level. Case1: common AS-SNPs already observed in individual cell line maintain the statistically significant difference in reads count between the alleles also at a population level. Case2: common SNPs that are not showing statistically significant difference in read counts between the two alleles in a single cell line might surface as AS-SNPs when looking for AS binding in the population.
