Genetic profiling included cytogenetic analyses and sequencing of 111 genes (Table S2 in the Supplementary Appendix). Sequencing data have been deposited in the European Genome-Phenome Archive (www.ebi.ac.uk/ega) under accession number EGAS00001000275. We based our analysis on variants that we classified as driver mutations, using widely accepted genetic criteria.12 (link) Recurrent fusion genes, aneuploidies, and leukemia gene mutations, including base substitutions and small (<200-bp) insertions or deletions (indels), were all included as drivers.
