Distribution of driver mutations in 3 independent SB models of T-ALL. Each gene identified as a driver mutation in one or more models is represented as a circle. The connecting lines indicate each gene's association with one or more T-ALL models (represented by gray boxes). The frequency of transposon-induced mutation in each gene is indicated by its color (white, 10%-20%; blue, 20%-40%; red, > 40%). In cases where a gene was identified in multiple models, the highest mutation frequency is indicated.
