Figure 1. Linkage disequilibrium (LD) display in Haploview of (A) the three SLC2A1 single nucleotide polymorphisms (SNPs) rs3754219, rs4660687, and rs841853. Left: D’(D prime), Right: r2 (r square) (B) all the 22 SNPs in the SLC2A1 gene with minor allele frequency>10% screened in this study and illustrating the nine distinct haplotype blocks. LD scores: D' (D prime) displays the raw D' value, which is the normalized covariance for a given marker pair and the correlation coefficient r2 (r square). Darker shades represent stronger LD.
