Researchers at Karolinska Institutet, KI, and SciLifeLab have together with colleagues in USA identified mutations in blood, which considerably increases the risk of developing various types of blood cancer, like leukaemia. The discovery, made by Johan Lindberg and Henrik Grönberg at KI/SciLifeLab among others, opens up new perspectives for research in the field of early diagnosis and prevention of blood cancer. The results were published in New England Journal of Medicine.
