Expression quantitative trait analyses to identify causal genetic variants for type 2 diabetes susceptibility

Figure 4 Population differences in expression of transcripts in adipose tissue is accounted for by the effect allele frequency difference of expression regulatory SNPs among racial groups. X axis: Fold change in average expression of 41 transcripts between African-American (AA, n = 37) and Caucasian (CA, n = 99) subjects. Y axis: Differences in strongest eSNP allele frequency of these transcripts between HapMap subjects of Caucasian (CEU) and African (YRI) ancestry for alleles associated with higher expression. eSNP: Expression regulatory SNP.
