Gene rearrangements and fusion genes identified in T-ALL patients. (A) Data are presented for 27 patients with T-ALL on whom we performed RNA-seq. Each column represents a single patient. Patients who were classified into the WHO provisional subtype early T-cell precursor ALL (ETP-ALL) are classified as defined (n = 4), and the remaining patients were classified as undefined (n = 23). MRD at EOI and EOC, and outcome data, where event indicates death or relapse, are shown for each patient and colored according to the key. Rearrangements identified by standard clinical test (standard) include gene rearrangements identified by either karyotype or FISH
