In chronic lymphocytic leukemia (CLL), certain recurrent genetic alterations are known to influence disease progression and survival. One important abnormality is the loss of part of chromosome 11, del(11q), which is associated with a more aggressive disease course. However, it has remained unclear whether mutations in the ATM gene, which is also located in this region, have a similar impact.
