Gene Abnormality Found To Predict Childhood Leukemia Relapse

Scientists have identified mutations in a gene that predict a high likelihood of relapse in children with acute lymphoblastic leukemia (ALL). Although the researchers caution that further research is needed to determine how changes in the gene, called IKZF1 or IKAROS, lead to leukemia relapse, the findings are likely to provide the basis for future diagnostic tests to assess the risk of treatment failure. By identifying this genetic marker in ALL patients, physicians should be better able to assign patients to appropriate therapies.
