Kajsa Paulsson and colleagues performed whole-genome and/or whole-exome sequencing of 51 cases of high hyperdiploid pediatric acute lymphoblastic leukemia, which is characterized by a massive nonrandom gain of chromosomes. They found that high hyperdiploidy arose early during leukemogenesis and was the main leukemogenic event.
