Figure 1From: Associations of a PTPN11 G/A polymorphism at intron 3 with Helicobactor pyloriseropositivity, gastric atrophy and gastric cancer in Japanese Linkage disequilibrium (LD) between the 9 single nucleotide polymorphisms (SNPs) with a minor allele frequency > 0.05 in the PTPN11 gene region among Caucasians (CEU: Utah residents with ancestry from northern and western Europe). LD maps are shown by two parameters, r 2 and D' for Caucasians (CEU: Utah residents with ancestry from northern and western Europe). SNP numbers in the LD maps correspond to the rs numbers described in the upper right of the maps.Back to article page
