Figure 1: Linkage disequilibrium structure of 17 SNPs in FADS gene cluster in Chinese Han Beijing (CHB) population.
From: FADS1-FADS2 gene cluster confers risk to polycystic ovary syndrome

Top portion of the Figure 1 shows the position of 17 SNPs (from UCSC Genome Browser http://genome.ucsc.edu/cgi-bin/hgGateway). Values in the box below show the LD value (D′) between the SNPs.
