Figure 1. Linkage disequilibrium between the single nucleotide polymorphisms identified by resequencing in the CFH gene in Mexicans. The LD for SNPs is displayed in white for r²=0; shades of gray for 0<r²<1; and black for r²=1. The r² values between any two SNPs is listed in the cross cells. At the top, a schematic representation of CFH shows exons and introns where are located each SNP.
