Comparison of allelic expression in blood vs LCL vs breast tissue. (a) Heterozygote individuals are represented as dots and are coloured blue for blood, black for LCL and green for breast tissue. The mean value for each distribution is shown as a red dot, and whiskers represent the 95% confidence interval of the mean. Dotted lines delimit the cut-off of 1.2 preferential allelic expression ratio [log₂(1.2) = 0.263]. (b) Pairwise correlation analysis of the mean log₂ allelic expression ratios for the three sample sets. Genes are identically colour coded in all three graphs. Dotted lines represent the linear regression applied to each tissue pair, and the respective equations and R² values are indicated on each graph.
