Neighbor-net network (a) and neighbor-joining tree (b) of the estimated haplotypes of five EGLN1 SNPs. The observed number of haplotypes is indicated in parentheses. The neighbor-joining tree was constructed after removing haplotypes with a sample size of < 5, and the number of internal nodes represents bootstrap values (1000 replications). Red characters represent highlander alleles of each SNP. CT, GT, GC, and CC haplotypes were defined by rs12097901 and rs2790859 alleles. CTA and TCG clades were defined by rs480902, rs479200, and rs2808611 alleles
