A Genome-Wide Gene Expression Signature of Environmental Geography in Leukocytes of Moroccan Amazighs

Figure 2

Volcano plots of statistical significance versus magnitude of differential expression between locations.

(A) For each transcript, significance is shown as the negative logarithm of the P value on the y-axis, and the log base 2 of magnitude of mean expression difference is on the x-axis. Dashed lines indicate the threshold for significance (green: P<0.05, blue: 1% FDR, and red: Bonferroni adjusted P<0.05). The Venn diagram (B) shows the numbers of differentially expressed genes at 1% FDR for each comparison and the overlaps between them.
