Figure 1. Linkage disequilibrium map of VEGFA single nucleotide polymorphisms. Two haplotype blocks (bolded) were identified for the nine single nucleotide polymorphisms (SNPs) in the vascular endothelial growth factor (VEGFA) gene. A linkage disequilibrium map of these haplotype blocks was generated using Haploview. Length of each block is provided in kilobases (kb), and pairwise linkage disequilibrium (D’) is given for each SNP combination. Dark red shading denotes D’ values greater than 0.80, and empty squares indicate D’ values of 1.0.
