Association between genes with ASE and gene mutations or cytogenetic aberrations. Statistical association was computed with a 2-sided Fisher’s exact test and represented as −log₁₀ (P value) for odds ratios >1 or log₁₀ (P value) for odds ratios <1. Positive values, indicating positive association, are depicted in red, and negative values are depicted in blue. For clearer visualization, the limits of the scale were set at −4 and +4. Associations that achieved significance are highlighted with an empty (P < .05) or full (P < .01) circle.
