Haploview LD plot. The plot uses the hapmapPhase3 data on the CEU and the TSI Caucasian populations and encompasses an 800 kbp segment containing the associated SNP on chromosome 6 and <i>HTR1E</i>.

<p>The LD blocks were defined by confidence intervals according to Gabriel and colleagues <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0035041#pone.0035041-Gabriel1" target="_blank">[45]</a>. The x-axis corresponds to the genomic position in kb and the red triangles defined by black lines represent LD blocks. The yellow arrow and the red box indicate the location of three GWAS associated SNP and the position of <i>HTR1E</i>, respectively.
