Figures & data

Table 1 Genes and their SNPs that have been found to be associated with chronic mountain sickness

Figure 1 Pairwise LD for 18 SNPs in the non-CMS Tibetan Chinese group (A) compared with the CMS Tibetan Chinese group (B). The degree of genetic linkage between the 18 SNPs in each study group is estimated as Lewontin’s coefficient [D’] where no color ([D’] = 0) indicates that LD is weak or nonexistent and the dark red ([D’] = 1) indicates that there exists strong pairwise linkage disequilibrium between SNPs. Blue bar indicates tagging SNP (rs699947).

Abbreviations: LD, linkage disequilibrium; SNP, single-nucleotide polymorphism; CMS, chronic mountain sickness.

Table 2 Changes in pairwise LD from between 18 SNPs in the CMS Tibetan Chinese group compared with the non-CMS Tibetan Chinese group

Figure 2 Pairwise LD for 18 SNPs in the CMS Tibetan Chinese group compared with the non-CMS Tibetan Chinese groups from is graphed between the pathways. Figure (A) represents an increase in LD in the CMS group compared with the control group, whereas figure (B) represents a decrease in LD. The numbers are the pairwise associations.
