The placement of significant SNPs within the EPAS1 gene. The –log(p-value) for individual SNPs in the region is indicted above the assembly of EPAS1 genes. The green line represents genome wide significance. D’ values are shown. The SNP shown, BIEC2–310909 (rs69041973) was highly significant (p = 9.27 × 10-8). This SNP is an intronic SNP with no known function.
