Whole-genome sequencing identifies recurrent mutations in chronic lymphocytic leukaemia

Analysis of the genomes of four patients with chronic lymphocytic leukaemia, and validation in more than 300 patients, has identified four genes — NOTCH1, MYD88, XPO1 and KLHL6 — that are recurrently mutated in the condition. Mutations in NOTCH1, MYD88 and XPO1 are thought to contribute to the clinical evolution of the disease. Evidence that NOTCH1 and MYD88 mutations are activating events highlights them as potential therapeutic targets. Chronic lymphocytic leukaemia (CLL), the most frequent leukaemia in adults in Western countries, is a heterogeneous disease with variable clinical presentation and evolution1,2. Two major molecular subtypes can be distinguished, characterized respectively by a high or low…
