Extended Data Figure 4: Derived allele frequency of the SNPs with the largest frequency difference between Tibetans and the 1000 Genomes Project populations.
From: Altitude adaptation in Tibetans caused by introgression of Denisovan-like DNA
At these SNPs, the frequency difference between Tibetans and the 1000 Genomes project populations is 0.65 or larger. Positions 46571435, 46579689, 46584859 and 46600358 were not called as SNPs in the 1000 Genomes data, so we assume these positions were fixed for the human reference allele. Note that even though position 46577251, 46588331, 46594122 and 46598025 appear to have a frequency of 0.0 for the populations in the 1000 Genomes data, the derived allele in these SNPs are observed at very low frequency in at least one population (for example, CHB).
