Basal activity.
Left panel: Haplotype effects. Differential luciferase reporter activity in transfected pheochromocytoma (PC12) cells. Here only the 3 most common haplotypes (frequency ≥10%) are shown, based on the 4 common promoter variants: C-824T, G-801C, A-581G, and G-494A. ANOVA is shown for haplotype number as the independent variable. Results of ANOVA are shown for the haplotype as the independent variable, and luciferase activity as the dependent variable.Right panel: Individual SNP effects. Results of ANOVA are shown for the individual SNP as the independent variable, with luciferase activity as the dependent variable. A −log[10]p value plot is shown for significance of each of the 4 common variants.
