Distribution of the PPA along the genome The PPAs for SNPs analyzed in ref. 7 are plotted along the genomic coordinates [National Center for Biotechnology Information (NCBI) build 36]. We omitted 767,877 SNPs with PPA < 0.0001 from a total of 831,532 SNPs. Fifteen regions analyzed in this article (i.e., those regions containing a SNP with 0.1 < PPA < 0.5 but no SNPs with PPA > 0.5) are shaded in gray.
