Figure 1: State of linkage disequilibrium (LD) between the SNPs within the exon and intron regions and approximately within the 10 kbp 5′- and 3′-flanking regions of the AKT1 gene on chromosome 14, based on the genotype data of the 300 samples used in the initial exploratory association analysis. Numbers in squares in which two SNPs face represent the percentage of and values calculated from the genotype data of the SNPs in (a) and (b), respectively. Blank squares represent or .
